What the heck is a video mixer?

[@mikkowilson2]

TD here. I use the manual T-bar mostly during artistic programs where the feel of the timing or pacing of the program and transitions is highly subjective. For example I'll use it during concerts to "feel" out the speed of dissolves/fades live on the fly in sync with the musicians. E.g. The camera zooms in slowly as the violinist draws out that last slow sensual note and we fade in time to the wide shot where everything "lands" in harmony and it just "feels" "right". My favorite moments of TV magic are when the all the parts, including time (which is what the T-Bar is for) come together to make something special.

[@ki85squared]

Spot on! Consistent, evenly timed transitions aren't always desired, and the T-bar is the perfect intuitive interface for the task.

[@NonCompete]

Re: "who uses the cheezy transitions?" I used to do technical direction for live events, rock concerts, churches, etc., and the answer is churches. Churches can't get enough cheezy transitions! And I would imagine the vast majority of switchers ever purchased were for churches. They are also used a lot for "image magnification" aka "imag" at live events. Probably the funnest work I ever did in live video was calling shots on those things, it's like playing a video game and you get to wear a big headset and play with the jet fighter controller t-bar!

When the community TV station I work at started in 1993, our first switcher was home-made. It was just a button that mechanically switched between the two consumer VHS camcorders that served as our first studio cameras. It was dubbed the Bang Box, and when you look at our earliest shows, the picture would roll every time you switched to the other camera because of the lack of sync.

[@themaritimegirl]

​@@CathodeRayDude Other things I'll add: I've never heard the term hot-punching before, and I find it funny that it's considered taboo sometimes. We use both methods depending on what we're doing. If we're taping a talking head show with three cameras, we'll hot-punch because you can just keep three fingers on the Program row and it's easy. If we're doing something like Bingo that uses the Key inputs on the switcher to overlay cameras on top of the bingo graphics, you can't hot-punch because it will change the bingo graphics to a camera that has other cameras keyed on top of it, and it's chaos. Ask how I know 🙃 As far as transitions go, the only thing we've ever used besides a dissolve or a wipe is during our live Christmas telethon, we'll use a media wipe with pretty snowflakes to transition between the studio and the pre-recorded clips of kids singing. The only thing I've used the T-bar for was to do really slow dissolves when we had a musician in the studio giving a performance. That's how you also do that thing where you partially dissolve between a wide shot of the musician and a close-up side view of their face. On a good switcher, the T-bar is dampened with what I can only assume is really thick grease, so it's very easy to get smooth transitions using it.

oh man the room was VERY crowded. I didn't take a picture once it was all set up, but you're absolutely on point that it was hard to squeeze it all in. I had two Blackmagic pocket cinema 6Ks running, one on a big tripod with a teleprompter, one on a little manfrotto video tripod, but both trailing cables across the room; then I had another big tripod with a Sony shoulder-mount ENG camera, and a second Panasonic ENG camera sitting on a pile of boxes on top of a rolling cart on the other side. A huge cable snake down the center of the floor to get video in and out of the mixer rack module in the other room, plus the boom mic stand and cabling, and three LED floods with softboxes. Me and my gf (camera op) had to climb over cables and squeeze around the back of the presentation desk every single time we had to move anything.

I'm a Technical Director for a news station. you got the basics! DVE can be super useful. You can place multiple cameras in PiP (picture in picture), then make another scene with those PiP windows in different places. Store them as memories and when recalling them, the mixer will interpolate/animate the movement of the PiP windows. I use that for taking either the outdoor studio camera or weather map, gives the PiP windows a neat zoom in transition. Our lower 3rd and full screen gfx inputs are still called CG, but they're fed by a PC playing back transparent pro res files. What in gods name was that audacity skin? I like it!

Glad to see the mixer I saved from e-waste and sent to you will live on forever in this video! I did a bunch of shows on this unit and you found features on it that I didn't know existed (the dip wipe!) but you're right - we never used the fancy DVEs, it was mostly cuts / dissolves, downstream keys and chromakey. I'll point out that the grass valley switches have the program bus at the bottom, and echolab had the preview at the bottom - for someone that would do weekly shows at 2-3 different studios I had to always remember to switch - or else you might cut live at the wrong moment! (and that did happen!). Great video!

[@adamgrunseth]

I really enjoyed this video. Having worked in broadcast TV news for 10 years, and now running my own production company that specializes in on-location, live, multi-camera production, I use video switchers on a regular basis. So, seeing the collection of video mixers you had gathered here was a lot of fun for me. There are a few things I think I might be able to clear up. First, on the topic of A/B style switchers (SFX generators) versus Program/Preview bus switchers- A/B switchers, like your Panasonic switcher in this video, were mainly used in video editing applications, where program/preview style switchers were/are for use in live multi-camera production. Before computer based video editing was really a thing, video was edited tape-to-tape. The simplest form of this was having a playback deck and ar record deck. You would have an edit controller, or controls on the tape decks themselves, to mark in and out points and record just those selected sections to your program tape. However, if you wanted to edit something that was more complicated, and had more than cuts only editing (an entire TV show for example) you would have multiple playback decks and your record or program deck. A special effects generator, also known as an A/B style video switcher, would connect all the source decks to your program deck. You would use this along with an edit controller, that selected your various in and out points and controlled tape transport, to actually edit the program, with your video mixer performing the various dissolves, or keying in things like titles. This is why the Panasonic video mixer has built in audio capabilities, for four audio tracks, the standard number of tracks that were supported on professional Betacam tape. This is also why you have the program select button, you could select to send the program output to a third playback deck, in case you needed to dub scenes from one playback tape onto another, to allow you to perform an edit where you dissolve between them. Typically, the edit controller would also have a preview button, allowing you to preview an edit and rehearse a dissolve or affect before you hit the edit key and committed it to tape. So a preview bus output on the mixer wasn't needed. The reason why you had an A/B bus, instead of a program/preview bus, is that this kind of editing came from film editing, where you would have an A-roll and a B-roll. These kind of video mixers were also known as special effects generators because that was their intended purpose, to insert special effects in editing, not to be used for live television production. In an online edit suite, where you would edit a full and complete TV program, you would have multiple playback decks, a master record or program deck, an edit controller, a character generator, a special effects generator (or A/B switcher), and a basic audio mixer if the switcher didn't already contain one. The second thing I think I could shed some light on is why a TD would use a T-bar for a transition instead of the auto button- There are two answers to this- First, sometimes you just want to. There isn't a reason to use the T-bar instead of pushing the auto button, but when you've been doing a 4 hour long broadcast morning show, using the T-bar every now and then helps mix up the job a bit so you don't fall asleep. However, the bigger reason is something I do frequently in my work, which is during live coverage of musical performances. Sometimes during a slower song it is appropriate to do an extra slow dissolve, while other times a dissolve is appropriate, but you want it to be a lot faster. Next, I'd like to address how and when all those DVE transitions and wipes are actually used and what they are there for. It is true, on a basic 1 M/E switcher they don't have much use. However, when you are switching a program with multiple M/Es you can use those DVEs to build various scenes, combined with keyed in graphics on the M/E you could build things like boxes, where you have multiple reporters on location and your anchors in the studio for example. In these cases, the T-bar on these M/Es might be left in a partial position. But you can get these elements setup on the M/Es before the show, or save them as a macro, depending on the switcher you are using, and then during the program bring up that scene you built in the M/E as a source. The DVE's aren't really for doing transitions, but for building these kind of scenes or elements.

[@CathodeRayDude]

Thank you so much for all of the info, I will integrate this in future presentations!

[@micaelsilva]

I was going to say that, that was lot of sense to use a T bar in a musical due the variable timing in it

[@scorinth]

"film editing, where you would have an A-roll and a B-roll" Wait, is this where the term "B-roll" referring to some unrelated shot you'd cut to when you want to hide an edit came from?

[@micaelsilva]

@@scorinth Yes

[@adamgrunseth]

@@scorinth Basically, yes. Before video tape, TV news stories were shot and edited on actual film. Back in the day it would be normal to have a news anchor give a quick brief of a story, the promise, "Film at 11:00." For quickly editing these news stories, you would have your A roll and B roll. Your A roll would have your package's sound track. You would edit your A roll first for sound. Then, you would splice in your B roll material. When the movie was made to videotape, these terms remained. Even though the tech was now different, you would still edit a news package for audio first, then go in and insert your "b-roll" material, even though your B roll was now a tape instead of an actual film roll.

[@UpLateGeek]

Fun fact: If you were downloading TV shows from the Internet back in the day, they would occasionally come out _before_ the show's airtime. These almost never had the station logo in the bottom corner because that's only inserted, as mentioned in the video, when the program gets played out. Not to get too deep into the weeds, but the station logo is typically inserted as the program is played out to the transmitter. If the logo isn't present on the program, that's called a "clean feed", which is how programs are typically transferred. The fact that the logo isn't seen on the downloaded program means it was captured from a clean feed at some point before the program was played out for broadcast.

Finally, someone else who remembers pirating pre-release shows! I'd get episodes of The Simpsons almost 24 hours before airing, it was great. My friends didn't believe me at first.

One other major massive difference between hardware and software based mixers is latency; how long it takes for a signal going into the mixer to come out the other end. A software based mixer needs to capture each frame into memory, transfer that frame over into the software, let the software process that image, and then render it back out to a frame buffer where hardware can turn it back into a video signal or an encoder can compress it into a stream. Couple that with most software mixers working with compressed video sources that also take time to compress, move, and uncompress for processing, and the time adds up more. The latency for a camera through a software mixer can be from a considerable fraction of a second to many seconds long. Thankfully most software mixers handle the audio too, so they also have some chance of keeping it in sync with the video. The delay in most professional hardware mixers is less than a single line of video end to end when working with synchronized source signals, and typically one frame of working with DVEs. If you need to buffer your incoming signals to synchronize them, that adds up to 1 frame, on average half a frame. Having a minimal delay of course is important to keeping things lined up with the audio that's being processed elsewhere, where a short consistent delay can be compensated for. But while a TV or streaming audience won't notice or care about latency, anyone watching on a screen in the same space as the action; like a large video screen at a concert, sports arena, church, or conference hall; is going to notice that delay really quickly. When feeding cameras to screens, we want the light that went into the camera's lens being shoved back out to the projector as quick as possible. We'll run sync/genlock cables out to our cameras and turn off all the extra frame buffers along the way to try and keep that delay at under a frame (one 30th of a second [~33ms]) all the way through. Which is how long it takes for the sound from the speakers to move about 37 feet, which is a reasonable distance to many of your closest audience members for things to still line up in our brains.

[@fordesponja]

Having in count that streaming services have a quite big delay by default, in the order of 20-30 seconds at least and usually streamers force an artificial delay of minutes to avoid game ghosting or manage chats, it's understandable that software mixers are good enough for that while that latency is bad for live TV.

[@miawgogo]

@@fordesponja that sounds quite bad, and im not sure what service your referring too, twitch often has sub 10s latency(measured in a not very accurate way of chat messages and when they show up on stream, ive seen the latency debug output get as low as 1.5 secs, but im not sure what that’s measuring) and there where some attempts to get it quicker with the likes of mixer

[@thewhitefalcon8539]

This is a side effect of high level abstracted and modular thinking of modern software dev. Instead of having specific wiring for a specific effect, you put together this input card, general purpose processor, and output card, and now you can do *anything* to any part of the frame, which is really awesome - except it adds some frames of latency. Open your phone camera app wave your hand in front of the phone - you can see the screen is delayed. Your phone is capturing a whole camera frame, then the whole frame gets passed through some specialized processor (to save power) that does brightness and colour balance stuff into the main system RAM, then the camera app notices the new frame is ready in RAM and queues it up for the next time the screen refreshes. When the screen refreshes the graphics system puts together all these pending sub-frames (status bar, app, soft button overlay) and now that's ready for the *next* screen refresh. It's basically put together by the creator of each part thinking about what to do with entire frames and not individual pixels as they come in, so each part of the system adds 1 frame of latency. To be clear, it's totally fine for a lot of applications. --- There's no theoretical reason a software couldn't process pixel-by-pixel, but it would probably still add a few pixels of latency so genlocking the output with anything else would be tricky, but if it's the final output maybe you don't care about that.

41:50 One application for using two _program_ versions is during a concert. You can have one output going to be tapes, or broadcasted. While another output is for sending a signal to on-stage screens. This way you can have a wide shot aired, with a close-up of the singer on the screens that are located on the stage. Having the same image would result in the Droste effect, where the on-stage screens would display the same shot as the wide angle shot. So, the shot repeats itself in the screen... over and over again.

JD the TD here. Loved your video and great job in explaining a very complicated subject in layman's terms. I am a broadcast TD and use the big giant Sony and Grass Valley Keyenne switchers shown in your video, on a daily basis, but have also used many of the older examples too. My first switcher in church, was the Panasonic WJ-50. The Preview output that you mentioned not being able to find was not to preview a bus, but to preview an effect like a chroma key or downstream key(dsk), etc before taking it. I also remember using a larger echolab switcher in a remote truck in the late 90's. It had a Pgm/Pvw bus, but the two additional M/E's were A/B buses. It was very confusing to have both on the same panel and "bagged" me several times each time I would get called to use it. It's like Echolab was too cheap to make all three M/E's flip flop like Pgm/Pst, but by having it on one, they could be competitive with other brands that had it on their switchers. I hated that switcher! The most challenging part of running the big broadcast switchers is remembering where things are located in the menus to do what you're trying to accomplish. Most productions that I have been a part of have a separate video director calling the cameras but there have been the occasional shows where I have done both or "called and punched" my own show. What the general public has to know is that television production is a field where there is very little tolerance for errors. It requires a great amount of focus and mental stamina. It's more that just hot punching two or three cameras, like in your video. It can be more like punching 5-7 cameras on a talk show or game show, and then being expected to record multiple shows, flawlessly, in the same day. Or being on a LIVE to air show like the news for four hours straight or cutting a music show or sporting event with more cameras than you have fingers and being expected to hot cut on the beat. By the end of the show, you walk away and your mind feels like a bowl of jelly. It is not an easy job in the least bit, but if you are good at managing a lot of signals and multitasking, can be very rewarding.

[@volltesdalTV]

A few comments from someone who worked as a vision mixer (which is "european" for TD) around ten years ago: - At least in my area, the only type of production I worked in where one would use preview for cuts was in news, because of the rapid, scripted cuts you would have to make. Your right hand would be ready on the cut button for the next cut, while the left hand was ready to preview what came after that, so you always had the next two cuts ready. Anything else we were taught to cut like the BBC vision mixer is demonstrating at 23:48, left hand for cuts and right hand for dissolves. Using the pvw row for cuts just adds an extra step that you shouldn't need; a big part of the job is always staying one step ahead so you know which cameras you can cut to before you need them. - About the wipe patterns and the other "fun" effects, you're right in that they hardly ever get used. Mostly they're used to hide the transition that happens behind a stinger (if it never goes full screen so you can just cut behind it), and even that usually just needs a regular linear wipe. But you never know when someone will have an idea or request for an effect or transition that needs it, so why remove them? There are other things in the mixer that depend on pattern generators anyway, so adding/keeping a few "extra" generators in order to keep the wipe functionality is probably no extra cost at this point. - ME steps are commonly used. Mainly, as you say, for "submixing" of effects. In most cases, you could in theory do everything on the program row, but it is much simpler and safer to prepare an effect on an ME so you can just cut to the finished effect, especially when you need to load different snapshots or effects during a show. If you build the effect on an ME, you can just quickly store a snapshot of the entire ME and know that it won't affect anything on your PP (program) step when you recall it. Another benefit of the ME's is that you can have more than one panel/control surface controlling different ME's on the same mixer. For example, on mid-size sports productions, we sometimes use the main control room in the OB truck for the "host" production and the "second production" room for the "national" production. Since they're technically just different ME steps on the same mixer, the national production have access to all the same sources in addition to the host output.

[@robmusial]

TD here (Blackmagic ATEM Production Studio 4K), a lot modern video mixers have audio. One of the main uses is automation in AFV/VFA (audio follows video/video follows audio). But as you speculated the internal media players use it as well. It also is a great way to set limits, etc.

[@ahmetrefikeryilmaz4432]

I worked as an interpreter for a news network for about six months and I have never more than maybe ten keys on what was a gargantuan mixer. Audio was strictly a separate affair. The t-bar was frequently used though. They would use it to perform cuts from different sources. Sources would be news agencies. Here's an overview of what went down, or whatever I deduced from observation: The network I worked at didn't have any news broadcaster or any sort of live feed that is shot within the premises, i.e. the modus operandi of Euronews. Agencies have constant video and audio feeds that the network had subscribed to. There are monitors in the production room that exclusively display one particular agency. The director seems to have notifications come to them from a RSS feed or something like that about the contents of each agency feed. The director gives the general direction but I actually did that in their stead from time to time if you can even believe that. Anyway, the TD would pick a source, preview it with its audio using either a headset or a little loudspeaker but that was just to check whether or not there was proper workable audio. The CG operator prepares the text, something like "man marries his sister in Alabama", wraps the text in whatever graphics and adjusts the graphics as necessary, then feeds it to the mixer. The channel logo, the date, or time seems to be added by the mixer but they are a rather standard affair since they were constant and I imagine they just press a key to display a whole bunch of them at the same time. The TD picks the feed, applies the logos and shit, applies the output of the CG generator which was typically referred to as "KJ" (abbreviation for karakter jeneratörü" in Turkish), then the audio engineer, who happens to be the best AE I have ever seen in my ten years as a simultaneous interpreter and I have worked with so many, listens to the audio feed, does necessary adjustments as he sees fit, then adds my voice on top of it. The t-bar was almost always used in transitions of any kind and I imagine it is to give the TD complete control of how things go down, something I observed to be essential if you want things to go smoothly. All these were what I could deduce on my own since TDs were not so eager to teach me anything as if I was gunning for their job or something. I am probably mistaken in quite a lot I have said so please correct me if you know better I really wanna know. Stellar content btw.

[@UpLateGeek]

What the wipe and other transitions were used for was mostly wiping graphics onto the screen. Back in the day, your lower third super generator just output a static image, so to get a nice effect of it sliding or wiping onto the screen, the vision mixer was the thing doing the transition between the normal shot and the same shot with the lower third graphics _superimposed_ on it - hence the term "super". EDIT: Ok, you kinda got there yourself. But yeah, by the time this box was on the market, it was doing the keying of the graphics all by itself. Before that, it would've come out of the character generator (CG)/Chyron/graphics generator, into a keyed the graphics over the shot of the talking head or whatever, and fed that as a separate input into the vision mixer, which would usually be called the "graphics" or "Chyron" input, depending on how American your facility was. Often the graphics operator would have their own mini vision mixer, so they could overlay the graphics onto inputs separately to the main vision mixer.

DB-25 parallel cables, around a max length of 25 to 50 metres!

[@oomredoo]

To add to what @dan b said: Each ADO unit he described was a *single* DVE channel! These were a separate piece of equipment to the switcher whereas modern switchers offer DVE on every upstream key. Each ADO channel was about 10-12U (?) high of rack space at least, about the size of a bar fridge. You’d get two in a full height rack. The 4ME GVE Kalypso I used later on was smaller than 1 ADO. They worked just like a Character Generator would with a mixer. The ADO provides both a video output and a key output. The key output is a black and white video channel that the mixer used to dictate the shape of the key. This is known as External Key, you can even do it "manually" with two cameras. Mixers would either have specific key inputs, or inputs programmed to be tied into video and key pairs. The ADO terminal you showed a picture of at 27:58 @Cathode Ray Dude [CRD], is the Z80 based microcomputer controller as described in the manual. This did the math part of the effect geometry, key framing and file storage. The ADO terminal fed the geometry to the ADO via a serial data connection. The data was real time - move the picture and you could see the numbers change. You can edit your effect by text input and even had copy and paste functions so you weren't doing everything by eye. Because these things were so expensive, the terminals had a resource sharing system. You could “acquire” and “release” control of a DVE channel depending on how many you need. That way multiple studios or edit suites in a facility could use the ADOs as needed, using centralised video routing or just a patch bay. A TV station I worked at had 3 ADOs, shared between a studio and an edit suite. They normally sat at a 2:1 assignment, but the studio could borrow the third ADO when doing a bigger show. I helped one of our engineers replace a PSU one day. I remember us joking “200 amps would kill you, but the 5 volts would do it real slow”. They're the size of a small car battery. All linear PSU technology. The internals were amazing electronic design too. The “motherboard” was a backplane built with wire wrapping. Every connection is an individual hand placed wire. All the same colour too. While the quality of the video the ADO produced was quite dated by the time I used it. The unit as a whole was a joy to use. The terminal had a purpose built key layout and a full screen to display geometry data on. DVEs built into mixers all had to shoe-horn the data display into what's available in the mixer. Large scale units like the Kayene and MVS have a PC running their menu systems, but the DVE data still has to work with the overall layout. Like @Cathode Ray Dude [CRD] says: these things are a conglomerate of user interface and a great study in the possibilities to achieve the same outcomes.

The reason that old gear was built as a "rackmount" unit was because the workstations in the control rooms were (and to some extent still are) 19" racks. Instead of having a unit that sits on a horizontal desk, the desk itself is sloped and has 19" rack rails built into it, then the gear is mounted directly into the desk. If there's no gear in a section of desk (e.g. the director's workstation), they instead mount a blank panel into the desk.

One common use for multiple program outputs is also live screens on set or for events with a live in-person audience. For example the big screens for the live audience at a concert are there for close-ups of the musicians, and maybe some graphics or clips playback as part of the "set" and/or lighting design, but they wouldn't ever get the wide-shot cameras that are used to show the TV (/stream) audience the scale of the event. Skilled Directors or TDs will even synchronize content across outputs to build virtual "layers" through the real world: the wide shot of the concert stage where the crowd is going wild reacting to the guitar solo they and TV are seeing in a close-up shot on the screens that flank the stage... Then as the solo ends, both the TV program and the venue screens cut back to the lead singer together for the next lyric. Thankfully modern mixers/switchers also have a lot of automation features to assist the operator/s in managing all those outputs.

[@EdwinvandenAkker]

55:37 SD is still suitable for those screens at concerts. It is not needed for a LED screen that far away to be HD. As a matter of fact, tomorrow I work at a huge concert "Musicshowscotland" in Rotterdam _(The Netherlands)_ with SD LDK cameras on huge LED screens. Works like a charm.

[@kFY514]

In my TV viewing experience, the stingers are most often used when switching between a live feed and a replay in sports content. Like, regular cuts are for changing angles on the same action, and stingers are for... ehm, time travel. Likewise, in news they seem to be used most often when switching to a remote location or a prerecorded segment. So, even when not done particularly well or seamless, they still serve the purpose of marking the particular cut as a "bigger event" than just a regular one, as a visual cue for the viewers.

[@xanfsnark]

I think it's also relevant that you expect people to only half pay attention to the news (and sports, to a lesser degree), and only direct their attention to the parts of the broadcast they care about. A stinger usually gets animated in otherwise unusual, full screen ways, which is good for alerting peripheral vision that something is happening

[@bluein_]

I work at broadcast events for eSports across the globe, especially for CSGO and fighting games. We still use a traditional video mixer, generally a large blackmagic one just because we have one, but every passing day we are automating our broadcasting, whether it's hooking to an API to get game information and switching automatically or synchronising AR with cameras, lights, pyrotechnics and the like. We most generally use vMix nowadays. A LOT of vMix. Like, ~5 instances of it at a time interconnected at different parts of the venue, to create one cohesive broadcast experience. It feels like the general trend in gaming broadcasting is going towards having one "prod table" that takes care of EVERYTHING and connects directly to vmix to switch things around. Especially in smaller, one game one stage broadcasts we are completely skipping over the video mixing at times and connecting all cameras directly to a Decklink and using the XL streamdecks with Bitfocus Companion to use as a glorified mixing board.

I used to have an MX50 in a university video studio I worked in. You can get a straight cut between A&B busses by hitting the auto take button on the right of the T-bar, when the transition knob is set to minimum (all the way to the left). I do remember using this mixer with a programme / preview workflow - if I recall correctly, the preview output displays whichever bus isn't currently being sent to the programme output. I can't remember whether the auto take swapped the busses, or just simulated the T-bar switching over - I think the latter, as I have a recollection of the T-Bar's physical position being out of sync with the current programme output - hence the little red LEDs on the left of the T-bar to indicate which bus is live. Thanks for the trip down memory lane!

I think the grand-daddy of all video effects units came from a British company called Quantel. They had products with names like “Paintbox” and “Harry” (?) with six-figure prices, that could play around with video, in real time, in quite mind-boggling ways. If you look at old Kenny Everett TV shows, I think a lot of the mad stuff he did there was done with a Quantel machine. Then there was an earlier product called “Scanimate”. This did all its amazing video warping and shattering and stuff with entirely analog circuits. For a brief time, they were apparently renting this thing out to customers (mainly producers of TV adverts) for $10,000 a day. I think there is one unit left still functioning, in the garage of a former engineer of the company, who has a KZbin channel where he shows it in action.

We use DVEs mainly to set two seperate video feeds in a PiP-style setting, mainly controlled by the T-Bar for coarse positioning and then leave it there as we take the shot. Works great with artsy shots for jazz solos with a wide and a close up or even fancy music related live content mixed with the actual musicians, e.g. a circle of weird colors from a seperate feed off the LED wall and a wide shot of the same LED wall but with the band infront of it. But I mean... that were 2 out of 150 productions of last season, so DVEs are mostly just for kicks and to please creative enjoyment of our directors :D

[@tristangates2797]

If you are talking about analog composite video. If the two signals are synced, you can actually mix them with simple summing. That is how that old rack mount mixer you have there works. It's not doing any frame buffering or anything, it just switches video and will do summing if you do a fade.

[@KeyJ_trbl]

But that requires not just Genlock, but also synchronized phases of the color carriers? And, of course, it only works for NTSC and PAL ... which is why even in France, most studios used to work with PAL or component video internally and only converted to SECAM at the very, very end of the pipeline.

[@Curt_Sampson]

Short answer: no, you can't do simple summing. The longer answer is, if you have two perfectly synchronised monochrome video signals (which requires your sources to support genlock) and you sum only the video portion of those signals (not the sync within those signals) and divide the output by two, that would work. As soon as you want colour your signals must be RGB with each channel summed separately. But for composite colour video such as NTSC the colour is encoded in the phase of the luminance signal at certain frequencies. You could try synchronising the 3.57954 colour burst, and good luck with that when a quarter nanosecond difference will produce a major colour shift, but even if you could do that when you mix you'll see huge colour shifts anyway.

[@chouseification]

Since people seem to find this interesting I'll call out some of the gear we had in each of the studios (two large ones and two small ones). We also have several mobile truck studios which had similar but more condensed sets of more or less the same. Almost all of this stuff was rack mounted in a series of panels behind the switch board area (but within reach) and along the side wall. - the main video switcher - much larger than the ones shown in this video - ours had at least a dozen wipes/fades/etc and several modes to insert an inset (used way back in the day to show a scoreboard of a sports event in the corner of a live shot). Pretty nifty for the era, although far from top notch for the era (we were a public access station with decent stuff, not a major network affiliate). To run this, you needed to demonstrate mastery - this person has the greatest ability to make a goof, especially if you're doing live (for sports events, we often did). - VTR units - i.e. VCRs but of the U-matic 3/4" tape format - you'd have one unit set as master record, and several others where you could queue up various B-roll clips or the on-site shot you pre-edited; have your host introduce the video then cut to that tape, back to host once it's done. repeat, etc. - sound loop players - little short loops of audio in nice little tape modules - insert a pre-recorded audio advertisement, etc. Push the button and it immediately began playback - once done it would stop and be queued at the right spot for the next time - pretty neat for back then. - SFX/audio mixer board - same idea as the video switcher except lots of channel sliders; similar to a band's touring mix board but only a dozen channels or so. Nothing fancy like recording studio board (those have dozens/hundreds of channels). - master signal generator / genlock - a rack mounted master clock - it sent a signal to all the video gear and cameras to keep them in sync. A requirement for the old NTSC standard to avoid any flicker. - light mixer board - control the various lights in the studios - this was pretty fancy as we had a variety of plain roof lights, smoky gels, indirect, etc. Sadly not configured to use that protocol where you can send signals in real time, so somebody had to run this when you were doing a host intro and fade out at end of episode for the studio stuff. - studio cameras - generally three huge tripod mounted monsters - they did have a limited ability to move so we would set them up for a show then leave them in place. Wonderful setup - preview display on top with red light if master was using your feed (so you'd be careful not to do anything dumb), connection for headset so you could whisper to control room and hear their instructions - "camera 2 get a close up of guest", "camera 1 get wide shot" etc. while cam3's feed was being used. They had the nice hand grips and were very well balanced, so it was easy to aim it; zoom was a thumb control on one hand and focus (haha you expected auto-focus?) was a twist on the other hand. If you aimed at the lights for more than a split second you would ruin the tube, which cost at least a few hundred bucks to replace, so just don't do it. :D - a whole row full of preview TVs - one for each of the VTR units, one for "master out" and several others. - shoulder cameras - we had a few smaller ones more along the size of news gathering gear - but that took U-matic tapes, so were bigger than a VHS camcorder. Once again, don't point at the lights - although these were a bit more tolerant than the studio cams. - giant room full of audio cables and reels of video cables - audio was normally done via same stuff professional audio people use, nice rigid cables with XLR connectors that actually clicked and stayed connected :P Video was done via these at least 1/2" across cables containing 40+ conductors - the end connectors plugged in and you twisted to lock it in place. - Going out with a truck to do a sports event was similar but often with less gear - 2 or 3 cameras for volleyball - maybe up to 5 for homecoming football. The "fun" part about those events was needing to do setup and teardown - and making sure to place your precious cable bundles somewhere they won't be constantly walked on by people who just can't seem to be bothered to step OVER the obviously very expensive cable. I wish I was kidding - those video cables were like a magnet for "moms with high heels walking out of bounds because they think they can" and we'd have to shoo them away. :D This was the point in my life when I learned about rigger's/gaffer's tape - like duct tape but much much better (even if more expensive).

The camera down on the floor was doing a variety of crowd shots and band closeups (we knew when specific folks would have solos coming up, etc) but that was just a pimp daddy camcorder securely strapped to whoever's turn it was to do that rig. :P

@@chouseification yeah wasn't that fancy for the rubber cable guards at that time as I was literally 5 to 10 feet away from the band. Although I did do the music tent for our small local county fair (minus the animals so we call it an expo). we had a fiddle contest where all three judges decided that they were going to move into my tent and act like they own the place. And then they complained about being behind everybody and not really able to see the players, shockers it's almost like they were sitting behind the stage. Oh wait they were to the left. I do an international water tasting for 3 years now and I love offering up press feeds. And occasionally will have other groups come in and film like TV, documentary etc. I've only had one person who understood what that meant where I didn't have to explain and they took me up on it. I've also edited videos where having a direct feed from the board is so much better than having the room audio from a gymnotorum. Oh yes the fun situations that we find ourselves in. I got into a concert at a nearby local theater free for helping them tear down. Not only did half if not all of the people coming in have earmuffs on and hearing protection which made the entire thing a horrible experience for me the whole thing sounded better in the lobby over the fallback system. Oh yeah where was I going with this the old theater balcony needless to say started shaking with the spectators even made one person nauseous. It's nice that you got them kicked off and it's also nice to keep the responsible ones. Rickety structures ekkk. I was asked to film today or yesterday now at my local Art's Place, they had a kids art thing they did in their black box theater which has four posts and guess where I was I just barely managed to get angles and on top of that they had a band set up and a completely other weird angle that I had to jump back and forth between with one camera. I did it free as a favor so didn't necessarily feel like nor have the time to grab the second camera. Although I did get a compliment from the new Director, on how unobtrusive and how I got a decent angle and wanting to work with me again. The funny thing is under the previous Director I used to volunteer at the digital media center that fell apart consisting of a 3 cameras Community TV studio. There's a really small town near where I live and every so often they lose phone+911 service because the line somehow breaks between here and there. Lucky you still had service from what I understand a lot of lines get consolidated down to the point where they might've been redundant on either side of the street but after consolidation from some penny pincher are now running through the same cable.

[@playmaka2007]

Director/ TD here, great video! You got everything basically right! You're correct that the millions of wipes are hardly ever used. Manual T-Bar would be used when you want a slower fade/ transition done on the fly without reprogramming your preset transition duration. Also, in some circumstances, I will leave one source half faded over the other for a duration. You're also correct that you could do a rudimentary split screen in a pinch if you wanted to, but I haven't been in a production that has done so. For modern live broadcasts, say live basketball on ESPN, the real magic happens in the graphics computers that feed the switcher all the fancy graphics to your DSKs or MEs. The actual switching of many live shows is pretty formulaic, but the graphics are where it gets complicated.

[@brycejprince]

Okay, so yeah, the T Bar tends to be for when you want to do a variable fade on the fly. The auto trans tends to be your best friend as a TD. With regards to DVE transitions... as a local news TD, I typically only use 2, all the others tend to be "cheesy" imo. The two I do use pretty regularly are a lens flare effect (almost like 2 stars flying across the screen with a lens flare in the middle) and a page turn. I use the lens flare for lighter stroies, or for certain fullscreen graphics (like "If you or a loved one is in need of help, call this number"). I use the page turn to transition between multiple graphics in the same story. I guess I also commonly use a white flash, but I don't think that technically comes from a DVE since it's just a color being generated by the switcher. Anywho, like I said in my other comment... these things tend to go through automation in local TV news. So we have some central servers that feed commands to the switcher to get it to behave a certain way. It's really interesting how many machines work together to get a production going. For example, that loud thing you had, we refer to it as the frame. It holds ALL the technology for the switching, as well as several other things (oftentimes it has a multiviewer that allows you to view all your sources that are plugged into the switcher). The actual board with all the faders and buttons is mostly just something that allows you to manually interface with the frame, and isn't even required on many modern switcher setups (due to the automation aspect of things). These switchers also have the ability to send commands to your video server, graphics server, etc. (usually referred to as custom controls or macros). This allows you to pre-save some of the effects or transitions without having to manually recreate it every time. There's a lot I haven't even touched on, but the technical nitty gritty is what has kept me in the industry because the technology that goes into it is fascinating to learn and become more of an expert in. Thanks for the video! Even from my knowledge and perspective, it was really insightful to see from a more general technological pov. Your videos are truly fun to watch.

[@CathodeRayDude]

Thank you so much for enjoying the video and for the info. I've heard a lot about how modern productions, news in particular, have almost no human beings involved during the show other than the talent, and it sounds really depressing compared to the chaos of yesteryear. I would really love to have been involved 15-20 years ago.

[@brycejprince]

@@CathodeRayDude yeah, they've whittled it down in most newsrooms, taking out the TD (with a Director only), graphics op, etc. Some have even gone as far as getting rid of the camera op, audio op, and teleprompter. Luckily, the newsroom I work in is led by a guy who wants just the right amount of automation because he'd rather have human errors than technology breaking constantly.

[@imark7777777]

Interesting I have not heard of the term frame being used. It is fully understandable and I suspect it is some thing out of the telephone industry since a telephone switch is usually put together in frames which is also where we get the standard 19 inch rack spacing. It's interesting how the technology is overlapped and the terminologies drifted into other use cases.

[@lawrencedoliveiro9104]

I was thinking, those transition effects look useful for livening up changes between static graphics, rather than separate moving video sequences.

[@Aquatarkus96]

@@brycejprince As a TD working in a (mostly) fully staffed non automated studio, I hope they never change. Troubleshooting a sleepy cameraman is easy "Why did you have camera 1 and 2 switched at the start of the show" "Sorry I read the shots on my rundown backwards" "Understandable, our show airs very early in the morning and waking up takes time, just try to pay closer attention tomorrow, ok?" Versus potentially hours of fiddling with stuff and trying to reproduce an issue. We had one of our ME busses go 180 degrees out of phase on the colors yesterday (red became blue and blue became red) and engineering is still string to troubleshoot the issue over 24 hours later.....

[@leozdyck6226]

Professional TD here, mainly on Grass and Ross switchers. WIPES are kind of a misnomer anymore. We don't use them to transition between sources much. We use them all the time to create effects during preproduction. Not to actually wipe between sources during a shot, but you can create a circle wipe to wipe between a slightly darker version of an image to create a spotlight effect or I used it one time during an ESPN football show to put a circle around our location on a radar to show that there was a big storm cell about to pass over us. When you combine a wipe with an effects dissolve on an E-MEM, you can even have all of this animate. I have a couple of moves in my show just in case I need to pull out an animated vignette really quick or something.

[@tgheretford]

I've seen fast wipes used by NHK for news and emergency broadcasts. But that's the only place I have seen them. In Europe, news broadcasts use hard cuts and it might be because we see stingers as the exclusive effect of sports broadcasts.

[@brianblack4469]

I love this video! I've worked in video production for 10 years and its neat to see someone so interested in the most mundane part of my job. Some little notes I have about my personal experiences and what you talk about in the video.( Disclaimer I did not go to school for any of this, I learned as I went. I got a job on a video crew and 10 years later its now my career, so I might just be some yokel and I’ve been doing everything wrong this whole time) 1. Its funny that you mention running a broadcast with a dinky mechanical switcher but I have actually done that once. I had a baseball game where a foul ball struck my tricaster 400 and it would not turn back on. We used a 4 way SDI switcher to run the rest of the game and cut back to a camera pointed at the scoreboard every play so the viewers could keep up. 2. When it comes to transitions we also only use cuts or fades (or whatever branded stinger ESPN gives us(also we don’t call stingers transitions we call them “video cuts” not sure if that is normal or not)). My understanding is that the goofy transitions are largely used by churches, who have lots of money for the expensive switches but are not really run by artistically minded professionals. I have done lots of “live editing” using a mixer and never once used a transition besides a cut or fade. 3. We do the same preview/program switching for sports but usually leave one teams coach on the preview so I can grab the reaction to a bad play. 4. On the topic of sound mixing, it is by far the best job in the industry because you get a room all to yourself and nobody bothers you as long as everything works. You also get to hear all the gossip reporters chat about during the commercial break. I miss my sound booth days. 5. The T-bar is good for emotional interviews when you want to really “feel” the transition. I don’t use it often but many people I know use it exclusively, it might just be when you got into the business. I love the cut button. 6.When you mention big sporting events and how complicated they can be. Usually there is one or more co-piloting producers there to watch the feeds and help pick shots. Along with multiple replay operators it helps to not overwhelm the director with each individual camera feed. Sorry that was so long.

[@AndrewMackoul]

This video brought back memories from HS TV Production. We had the NewTek Tricaster.

[@RadioTheDrolf]

On an early video switcher I used at a public access TV station, you HAD to use the take button. The switcher only had two frame synchronisers and the cameras we had didn't support genlock. So if you did a hot take to another input on the program bus there would be a huge tear in the image.

[@kellingc]

The SFX generator you showed at 53:41, or rather the big brother of it; a scond T-bar with a third bus in addition to your preview bus, chroma key, mat, and joystick. It was a PAnasonic withthe same color scheme as the one you were showing. The studio I learned in had two rows, split level. The upper row had the lighting panel, the special effects generator, teleprompter, and a space for the producer to make notes and oversee everything. Bottom row had your audio mixer, VTR 1, VTR2, with the timebase corrector above them, the Chyron (character generator) then your program deck, and engineering station that had you vectorscope, waveform monitor, and camera control units. Above the rack was the window o the studio, and above that were you camera VTR monitors, Program and Preview monitors, and the on-air monitor, and the speakers for audio monitoring. All this was in the late 80;s and analog, 30 frames per second, 525 scan lines. To set up a box over our news anchor's shoulder, you'd have C bus on program. You can then use the A and B bus and route it tot he preview monitor. On A bus, have the same camera selected as what's on your program. On B bus, you select the source you want in the box. Wipes were done on the A/B bus, and the disolves or fades were don between your A/B bus and your C bus. Select a square wipe. Split the T-BAR on the A/B section to size your x and y boarders (how big is the box), and use the joystic to move the box to reveal the information and mask off everything else. Use your second T-Bar to mix up from the C bus to the A/B bus. Seeing as how the the A bus is showing the same camera as your C bus, it looks like there isn't a change, but the box created with your B bus would fade in. Not only did we do live, but taped shows, and used the VTRs in the control for A/B roll editing. We didn't have non-linear editing. We would have to set our edit points, roll the tape back 4 seconds, start all three decks, and then either have a second person on the switcher to do the cut or dissolve between A and B deck, or reach over the counter from the bottom row and perform it yourself, We also had a mobile studio in the a box truck that we would use a lot, mostly shooting local high school sports. but it could be used as an A/B roll edit suite, too. I learned video engineering at that place - there's a totally unique aspect no one ever seems to talk about now days. As the engineer, I had to know every job on the crew, why an announcer's mic went out in mid sentence, fix it while live, set the white balance on the cameras in the middle of a shoot because the afternoon turned to evening on the Enfield;s baseball against Windsor Locks game is going past 7:30 and the color temperature has changed, why the sync generator quit right when news anchor was interviewing the state senator (the intern unplugged it so they could plug in a fan). You ever lose your black signal while live? It's bad. Man, I miss those days.

Gravis, on modern video switchers the automation systems such as overdrive are fed from the newsroom automation system, for example, Avid iNEWS, and all of the customs, video frame buffers and video playback, CGs, teleprompters, audio boards, routers, under monitor displays, etc are all sent in real-time to the switcher and everything is under automation. the TD basically then just hits enter, next, next, next, next, for the entire show. This is my main job at work now; the care and feeding of the automation systems.

I can see some interesting parallels like the large main lever on the right side of most units, which gets an equivalent analog lever on almost every recommended input system today going into a PC

[@Godzilla_Jesus]

Mixing console chassis were custom made furniture for these rack mounted devices. These racks were set up at angles to allow usability as the button farm grew. This was also when you'd build your own component setup. "I want Panasonic switching, Crown Amps, Sony Effects", that kind of thing. It's akin to guitarists building their own rack effects/amp combos back in the day, even pedal board combinations have now given way to amplifier sims. I was a pro guitarist back when all you needed was great hair, we used to call them spice racks. But back to the video side of the world, the days of custom builds like that are over. Modern products have everything built in, even the slope up/stacking in the chassis for the button farm. :)

Your Panasonic there is missing its ears (mounting brackets)

[@TeslabladePlaysMC]

55:10 I know the Stream Deck and other painfully expensive switchers exist, but if I were a high profile streamer using lots of cameras, I would love to use traditional mixers. Maybe it's for the blinkenlights and big buttons with positive feedback, but also because it just makes sense and looks cool in the process. Even if the mixer was just an interface device for software on a computer, it just makes sense. You just punch a button in a bus and you're previewing or streaming that camera, no need for a mouse or digging through menus. Sadly, from what I've seen, that's not a thing that exists, at least on a decent scale and price point for consumers.

[@UNSCPILOT]

Agreed, I'd try to find suitable little set of crt monitors to go with it, make the setup part of the show, so to speak. I might not currently have space for such a rig but I love the idea

Someone may have already mentioned this and I just missed it, but regarding all the rackmount stuff: bear in mind it's not just vertical enclosures; there were also desks designed to hold rackmount gear horizontally or at a slight angle.

[@tabbertmj]

On the Panasonic switcher, you should be able to set the time for the transition to the minimum, then use the button to cut. That was preferred on the one at our local public access station. We had one for portable setup's with two cameras. The reason to use it as a cut button is it has a built in TBC (Time Base Corrector) for each buss. Your inputs do not need to be genlocked. A test you can do, set up two inputs that have action. If you switch between them on one buss, there will be a delay of about one or two frames as it sync's the video. That didn't happen when going between the two busses. Hopefully they fixed it on later versions, but I doubt it. A quick edit. The built in TBC only synced the signal, no other adjustments that you could get with a good external TBC.

This is clearly the best introduction on YT into live mixing for people with computer experience but no AV knowledge so far.

[@MathiasTheGiant]

It is surreal to watch this video less than 2 hours before I go to work in a media studio.

[@AlRoderick]

Those special effects generators were rack-mounted because they weren't intended to be used "live" by the TD. There'd be one or more of those mounted in a rack along with the VT decks and other equipment and it would be set up before it was needed to generate a specific effects shot like the titles, credits, or the key for the weather report. The main switcher, which might have been an analog unit that was already in the studio for years without special functions, would cut to its generated output when it was wanted. The big Sony panel that was multiple switchers in one, that was collapsing the functionality of several of those into the main board in easy reach of the TD. If what you needed was effectively extra mini-mixers to feed the main mixer, the obvious form factor was a rack mount because you might need to cascade them or make them share inputs, but then main board doing the bulk of the work would be a console-style mixer.

[@DesertPunks]

[@yesthisisdonut]

i did an apprenticeship in media production (in germany that means you work for an actual company and get paid while also going to school every couple weeks) and i was (un)lucky enough to be put in a school where all the live production equipment was from the late 90s (i graduated in 2021). you'd have a BLAST looking at all the ancient shit we had to use. there was a room with 6 19' racks all the way to the ceiling that was the backend of the control room. video switchers really do come in all sizes and shapes, nice collection. i learned operating a larger switcher with all the bells and whistles, and LEMME TELL YA doing that stuff in a live environment was one of the most stressful experiences in my life. it was fun looking back, but jeez man. im pretty sure every second hand switcher you buy had a decent sweat patina at some point in its lifetime.

Very cool stuff. I'm primarily used to tools like OBS Studio but it's cool to learn more about the tools that came before. It is funny how many awful looking transitions there are in these mixers.

[@FatheredPuma81]

My favorite part is watching the news with all their expensive equipment get defeated by some random guy using OBS.

[@BenFranske]

OBS is not reliable enough or low latency enough for pro use

[@xWood4000]

OBS actually has studio mode which is based on the preview, broadcast thinking. I've understood that a big reason why people still use physical mixers instead of PCs is because chromakeying is much higher quality on dedicated hardware. I've wondered if OBS could use a full control mixer as a keyboard

[@EvilCoffeeInc]

I'm well aware of OBS's weaknesses, and while I'd like to get a hardware mixer someday, a) latency doesn't matter much for my projects and b) I'm not a professional. It's a pretty remarkable tool though, and the fact that an open source and free tool can do so much of what a studio mixer does is pretty amazing.

@51:04 now i know why this all looked waay familiar when you showed the panel i happened to build a control surface for one of the early blackmagic mixers (for the panel was way more expensive than the switcher itself) and ended up puttint those shift layes in verry similar spots, aka mix/dip and so on, as well as (of course) i kind of took some inspiration from the BMD control surface to map that to the panel i did (which was an ampex thing with no idea where it came from and to what it belonged originally)

[@JessicaFEREM]

This might be a hot take or completely true, but I have the feeling that OBS could be modified to be an entire production movie mixer. All it needs is a way to get a lot of sources in and a control deck. I think that's incredible considering it's free software. I could see entire productions being done on OBS in the near future, and to and extent I could argue that's already happening.

[@JessicaFEREM]

I will say however that reliability is nowhere near as good as production mixers, but it's certainly a lot better than any other option out there for low cost productions , at least at the moment

[@CathodeRayDude]

The problem with OBS in my experience is that it's too stupid to understand how to switch sources reliably. In a mixer, there's an abstraction layer. All the sources are constantly being ingested into framebuffers, so you can pick whichever one you like. In OBS, if you switch inputs on a source, it takes 2-4 seconds to initialize a new video device; and if you try to use the same source in two places, you can wedge the whole app. It's just not designed for it, and while you could _sort of, kind of_ hammer it into submission, it really just isn't built for this.

[@JessicaFEREM]

@@CathodeRayDude there's nothing saying it couldn't be redesigned to do things like that(open source software invites that), there are also dedicated PCIe capture cards, but it seems like the way it is now is not ready to be used for something that important. Although I could recon the "computer bs" could be fixed if you modified the OS to be dedicated for streaming and nothing else, but at that point it may be better to use something else, not entirely sure. I know Linux was used a lot for computer aided DJing and the first ones used a custom Linux distro designed to be dual-booted with windows xp. I could assume at some point someone has locked down their windows stream box or used Ubuntu studio to get more reliability, but OBS is OBS.

[@xWood4000]

@@JessicaFEREM It could probably be possible, but would mean a redesign from the ground up. Big OBS updates are enough work already, you would need to have a paid dozen of programmers to realistically make such a big change in a reasonable amount of time. And you're probably right about the OS too. Windows has a lot of overhead, but Linux has also a lot of overhead in comparison to dedicated FPGAs. That's why there's a market for hardware mixers. You can strip down Linux to its bare parts, but you can build something else better anyway in that case. But I'm not a software engineer (yet) and I have no experience in OS development. I was a TD in high school, and because the productions were so small there were a bunch of things that weren't industry standard.

The wipes are still there and mostly used (German TD [here we are called BiMi, Bild Mischer meaning picture mixer]) to transition thru a stinger that does not completely occlud the frame. So if we have a stinger that is max ocluding 30% of the image the desk transitions (automated) thru it

[@oomredoo]

There’s so many different discussion topics that come from this video. Technique, creative style rules, deeper history and even user interface. There’s so many points in my careers (plural) where having a control surface made for purpose would be an invaluable addition next to a mouse and keyboard. @Doug Johnson Productions made a great video about custom controls for video work last year.

[@therealdrawingpathos]

Great video! I learned a few things and I'm something of a TD myself, at least until the billion dollar corporation I work for changed my title so they can add new responsibilities without adding any pay. It's funny you point out the seat of the pants capabilities of a video mixer. The switcher I use costs half a million dollars and I never even touch it. I'm told that with the fancy system we have, I can do all kinds of things on the fly, but I feel like it's all on rails now. I do my job with a mouse and keyboard using software that automates everything. There was something romantic about having a full crew in Production Control, punching shots as the Director calls them out. Working as a team with the camera and audio operators. Yelling at the prompter to keep up. But those days are over for a lot of us. Now the cameras are all robotic and it's my responsibility to program them and keep them from crashing into each other, the more complicated the show, the more disastrous it can be to make changes once on the air. Nowadays I compose the shots, set the focus, put them on the air, run the audio, punch the graphics, cue the talent, roll the breaks, coordinate with the Hub during live network events (since they shut down our master control), sometimes I even have to time the show. Even the talent scroll their own copy with a foot pedal now. There's no one in the control room anymore but me and a producer. So I don't feel like the huge switcher we have really gives us half a million dollars of flexibility. On the other hand maybe I'm just not using it correctly, often we'll get new equipment (like robotic cameras) and literally only two days of training for it. Don't get me wrong, I love my job but it's changed a lot in the last 10 years. I feel like the last man standing. I have friends at other Stations who still run a full crew, but I'm sure their days are numbered.

[@famitory]

the switcher isn't quite the heart of the broadcast studio anymore, that'd be the video router, which is basically just the world's largest video matrix, since so much of what gets broadcast is controlled by automation servers rather than ops, even live tv has a solid chunk of automated sections. usually you have every single imaginable video source and destination connected to the router (the biggest baseband one ive ever seen took up two entire 42U racks and had something like 2048I/O, and the smpte 2110 ones can get even denser) and then the switcher gets only a subset of those, maybe 12 or 24i/o as relevant to the program.

[@tekvax01]

we have a (small) 512 squared SDI router, and a couple of 64 and 128 squared routers for QC monitoring. I worked for a network broadcaster that had a 2k square video router!

[@BenFranske]

Routers can be huge, but I would argue the switcher is still the hearts. Routers are one-trick ponys and can only do cuts (and not always clean cuts) so you actually want to transition between sources through a switcher. Most of the cool things you want to do (USK, DSK, fades, clean cuts) are coordinated by the switcher.

[@dj1NM3]

That Panasonic WJ-MX50 seems weird, because it seems to be treating video like a simple audio mixer deck treats sound (at least how a FoH/sound-tech would), just with the cross-fader moving vertically rather horizontally, like a typical DJ audio mixer would: two selectable (from 5 possible) inputs going to either end of the fader. One major difference to an audio mixer is that all of the inputs must be gen-locked (ie: the frame refresh and line-scanning are synchronised), otherwise trying to "simply" fade across with just a variable resistor (from one channel input to another) results in just video noise/static or no picture at all, except for either extreme end of the fade. It's also intended for live event VJing, rather than studio use, so it incorporates audio mixing, to create an "all in one" AV mixer. That simple AV switch box at 08:56 won't "cleanly" switch between video sources: the image will tear and/or go to static for a brief instant, because it doesn't lock (ie: genlock) the signals together.

[@AvinZarlez]

Software engineer here, and I super relate to the phenomenon you're describing. About things seemingly so complicated you can't comprehend them, and yet once you understand the pieces, it's actually relatively simple. I feel like that's how all of software engineering is. If all you ever written code wise is programming exercises like a bubble sort, writing a full software program seems impossible. But once you understand how to take everything, literally everything, and compartmentalize it... So much of my day-to-day work is about as complicated as that TD board. Metaphorically speaking

The BBC clearly spent thousands on Quantels when they first came out in the 80's and many programmes went mad with the DVEs they had, look at Top of The Pops from the time or things like the Kenny Everett TV show. It was a novelty at first but got so annoying they seemed to cut it back after a few years, perhaps real Vision Mixers could comment on whether that was a conscious decision from the BBC.

engagement!

The mixer you used in your demo looks so nice. I love it!

[@mhoppy6639]

Someone should tell George Lucas about wipes😂😂

31:00 I believe the reason why cuts are by far the dominant way to switch an input is just because it's the least distracting! We don't really think about it, but changing scenes is something your brain notes subconsciously and adjusts accordingly. Effects just draw attention to that process, which is why they feel so awkward.

Your little rant on Vmix reminded me about one my favourite lines at work which also is similar to something else you slipped in earlier but uh “all my homies hate WIDEORBIT!”

This is the most comprehensive video mixer video on KZbin. I just got a Sony MCS-8M you explained everything I needed to know about this subject. This mixer actually has an 8 track audio mixer.

FYI rack extrusion, nuts and rack wings is used to build out physical work surfaces (desk flat or at an angle or horizontally) in either the 19" or 500 series format.

Absolutely love the videos about the different cameras and what makes them unique. Not necessarily interested in that stuff as a collector or whatever... But I've enjoyed them thoroughly and rewatched your videos several times. The camera and gear videos are probably my favorite

[@morsikpl]

WOW! That's a really, really, really good video! Both in terms of knowledge and entertainment! Examples of transitions and layers directly on this video are great! This looks so much easier now for me, altough I do mix music live so I do have some mixing knowledge.

I used one of these back in the day for live editing weddings, theater productions, and my girlfriends' figure skating videos and then offer DVDs made before the event is over, or for live-editing skateboarders that goes right to a big screen at a competition. What a throwback, you're gonna get me to buy one of these for no reason now.

"Nobody's needed one of these for almost 25 years." EMOTIONAL DAMAGE

(had to finish this later) This was such an unbelievably nice treat and trip back in time. TYVM.

TD here too! In my past life I used to TD for live horse racing, and the wipe was totally utilized a lot. We used the horizontal wipe for races about halfway. Cam 1 up top would show a wide view of the field along the top half of the frame. Cam 2 would be tight on the first few horses on the bottom half of the frame. Stick a horizontal wipe transition halfway between the 2,with a nice feather and what you have is the entire field of horses tight, and wide. I would also use star wipes and the other wipes when I was bored.

Great video man, I can tell you and your friends are having a good time producing these, this was funnier than I was expecting and loved it. Also really appreciate the references to older videos about "how things work", like the Nimoy one. Keep hoping you're teasing the HVX for a video coming up on it. It is truly an amazing camera. Thanks again

57:14 our digital team uses vMIX for some streaming, but we also have a smaller hardware switcher that is compatible with it.

[@ravewulf]

We had one of those Videonics switchers at 28:04 and I don't know if it was just old or cheaply made but it sucked. If it got too hot in the control room during the summer, it would get stuck on one camera and wouldn't let you switch off of it until you UNPLUGGED IT AND PLUGGED IT BACK IN!!!! I was only doing local town board and commission meetings but it was still a nightmare for a live production. Night and day difference when we upgraded to a Tricaster Studio somewhere around 2007 or 2008

[@GxAce]

We had a home-made switcher at the City Council job I used to have. That thing was wood and quite a beast haha. Great video as usual.
