I would say do one of these in 70mm but I don't want you to get a big head.

[@bcwbcw3741]

Am I correct that the grain of 35mm film is about 1Mpixel at full width? Somewhere in that range, maybe 4MPixel. Having lived through the transition from film, I remember the big todo when digital suddenly outdid film. It was a while before the light sensitivity caught up but eventually digital also way outdid film. Kodak invented digital but suppressed it because they weren't really a photography company, they were a chemical film company. Pissing into the wind, they were.

[@circuitgamer7759]

I have an extension that helps with that. It forces the quality to be what I set in the extension, but it does mean that I have to change the value in the extension when I want a video in a different resolution. It was initially glitchy, but only for the first few days, and I have no idea why it changed.

[@VascovanZeller]

This is probably the reason for 24 fps - literally the fewest frames we could get away and not have the movie look like a slideshow.

[@JunkerDC]

yep that's why

[@scythelord]

Yep. 24 fps and the extreme cinema widescreen aspect ratios were never originally meant as artistic choices as much as cost savings. They just later became such distinctions due to a weird sort of stockholm syndrome. People just became used to that being the standard. There is no real reason to limit to them today beyond institutional inertia.

[@johnziniewicz6860]

Actually, 24fps was the minimum speed at which the 35mm optical sound track could reproduce an acceptable frequency range, and was not standardized until the release of sound films. For this reason, 24 is often referred to as "sound speed." But the speed varied from 16 to 30 (or other) during the silent era until this standardization took place.

[@JohnHarrisonForever]

It's not just movies shot on film! Lots and lots of television was shot on 16mm (because the lower resolution was impossible to notice on an analog TV) With certain prestige shots being shot in 35mm. Some shows even make the jump between formats as they become more popular. IIRC the first season on Breaking Bad is shot on 16, while later seasons are shot on 35. For a more recent examples, Succession and Euphoria where both shot on 35mm with Succession using traditional color negative film stock (same type as used in this video) and Euphoria using Slide film (Ektachrome) which has much more vivid colors. Some movies also mix formats. Christopher Nolan does this a lot in his films with certain sequences being shot in IMAX while the rest is 35mm to save cost. Danny Boyle's Steve Jobs shot different eras on different formats, with the first part on 16, the second part on 35, and the third part shot digitally. Now if, filled with enthusiasm from reading this comment, you immediately rewatch The Dark Knight, don't come crying to me if you have trouble spotting which sections are shot in IMAX! While the exact digital equivalent resolution of film is pretty debated, it's generally accepted that 16mm = 2k (or 1080p), 35mm = 4k (or 2160p), 65mm = 8k (~3600p) and IMAX is at least 12k (7680p). This means in practice it will may difficult to tell the difference between formats if you're watching on anything other than a top of the line TV connected to a 4K bluray player. However if you stream it, the difference might be easier to spot, as the more visible grain of 35mm would put more strain on the compression algorithm of your streaming platform resulting in a mushier image. Back to the subject of resolution, if you accept that 35mm = 4k don't go to see a 35mm projection in a theater expecting it to look the same as a 4K laser projector. Film like any analog format is subject to generation loss, and while the original camera negative might have a 4k resolution, the copy of a copy of a copy that you see in theaters will retain much less detail. And to add another wrinkle, in the early digital era many movies were shot on 35 but scanned, edited, and composited at 2k because storing terabytes of data was a lot harder to do in 2001. Because of this films like the Lord of the Rings trilogy will never truly have a 4k re-release because all of the post production was done in 2k, which would mean they would have to rescan hundreds (potentially thousands) of hours of footage, open their 2 decade old edit project and reconnect all their offline media, all the while hoping that the timing of the new scans is exactly the same as their original scans (so that they don't have to manually re sync) and then they would have to redo over 3,000 vfx shots in higher resolution, possibly starting from scratch because the software they used in the early 2000s (Shake) isn't compatible with modern operating systems. The end result of all of this would probably look incredible, but come at a cost of at least 50-100 million dollars (for all three movies). The irony of this is that today you can watch the original Star Wars (1977) at higher resolution than The Phantom Menace (1999). And as a reward for reading all the way through this impossibly nerdy comment, I will give you one more fun fact about shooting on film: In the days before digital editing, if you wanted your footage to play backwards you had to shoot with the camera upside down.

[@BenMagargee]

[@robtapp6400]

I will have to check out Euphoria, I loved shooting Kodachrome 64 (another glorious colour slide film similar to Ektachrome) back in my film camera days. It did produce some of the best photos I ever shot. When not on Kodachrome 64 I would use Kodak Gold 200, and B&W usually Ilford PAN F 100 or even 50 if I found it in stock. As for Lord of the Rings in 4K, sorry fans, but I could barely sit through the trilogy once and sure as hell not doing a second time to be bored by it in 4k.

Then you’d take the take up reel out and flip it around to run the other half of the film through the camera. Then after developing, they’d cut the film in half lengthwise, and splice the two pieces together.

Half frame. A few still cameras used a similar trick like the Olympus Pen series. Then you had Advanced Photo System cameras that let the user vary the length the image was captured to either save money or max quality on each shot. It morphed in APS-C digital sensors.

Film and digital act differently, for example it is safer to overexpose a film to retain detail, and safer to underexpose a digital camera to retain detail. There can be no direct comparison.

It does show how much a serious production can elevate film, and how old movies still hold up because of that, and not the technology.

[@sentinelav]

Eh, it's not accuracy. As someone who's worked with digital cameras their whole lives, it's less about accuracy and much more about the 'feel'. The fact that this organic medium is 4K, with over 13 stops of dynamic range, is insane to me. It's too easy to push digital beyond the scope of familiarity, and give an almost CG look to real footage. Some directors are much better at managing this than others. But in a low light scene, we expect to see some noise, because we don't get a clear image from our eyes either. When things are very bright, they don't clip, they roll off softly.

I worked for 30 years in the film industry, shooting films al over the world starting in the early 90's to today, and i have witnessed the full transition from film to digital starting with Lucas who shot the prequel trilogy on digital in the late 90s. there are positives to both, but what i have noticed and to the utter annoyance of us crews in the industry is the "over grading" of those digital "log" images, colours pushed to the limits of what could exist, to my eyes todays digitally graded streaming shows and films look surreal. a choice is being made by a DP and the grader and im not usually glad of it. you watch Raider of the lost ark was shot on Eastman Colour Negative II 100T 5247 in mostly Tunisian sunlight, it look beautiful and its what we would expect those environments to look like, now if it were filmed today, it wouldn't have the same magical feel. personally i love 2:35:1, i still have a roll of 100T 5247 and one day ill dig out my oldd Eyemo 35mm and shoot some practical effects for old times sake.

It was intended for low budget productions because of its economical use of film in the camera and because it allowed a very wide aspect ratio without the need for expensive anamorphic lenses. Director Sergio Leone used the format to great effect in his "spaghetti western" productions, many of which became classics, such as _A Fistful of Dollars_ and _The Good, The Bad and The Ugly._

As someone who does quite a bit of photography this was super interesting! Just regarding the way the colour changed when you changed film as that wasn't explained, those names "tungsten" and "daylight" determine the colour temperature that the film will be shot in. "Tungsten" refers to an old fashioned light but in modern use is warm indoor lighting, whilst daylight is obviously for outdoors. The reason the colour got warmer (which we actually refer to as colder but that's another story) after the switch to daylight film is that the sun is a much cooler light so that film in a way compensates to try and keep the colours natural. With modern digital editing this is very easy to fix in post but was more important in the days of film.

[@Spuzzmacher]

Yeah i did all my grandfathers films from 1936 through 1979. I was surprised to find the original aspect ratio of his camera was 2:1, shot edge to edge right over the sprocket perfs. Sometimes there were people & action taking place between the perfs so I realized I definitely wanted the entire image & wasn’t going to crop anything off. But zooming out wide enough to fit it in the 1080p scan meant lowering the digital resolution per film size ratio, so instead I went the other way and zoomed in to fill the frame vertically, making one scan of the left 2/3 of each frame and then a second scan for the right 2/3, then comping them together in FCP, aligning and gradient fading across the overlap. Inconsistencies in light and film speed ultimately meant going frame by frame blending each together. But then, bracketed a second set of scans for of each film one stop apart, to pull more image out of over & underexposed scenes, and blended that in. I have 34 reels and it’s takin me 4 years of spare time, but I have the highest resolution roughly 2k widescreen 2:1 scans I could get out of 8mm films. While at first I wasn’t sure it’d be worth the trouble just to view film grain, the difference in sharpness was visible, and the massive number of splices in those films (which each requires a reset of the machine, yay!) and edits in sequence made me realize my grandfather wasn’t just passively shooting footage, he was actually making films with a narrative in mind. His films switch to color in 1937 and take place all across the country, with pretty amazing historic things going on throughout. So it seemed worth the effort & turned out to be meditative & fun.

@@DanFre40 Ah. Well, there have been several projects published over the last few years to use an SLR-style camera to capture each frame. In most cases people scrounge a film-advance mechanism from a broken camera or projector and then 3-D print whatever pieces are needed to connect that to a motor. Some people overcomplicate it by having a microcontroller fire the camera, but all you really need is a cheap wired remote control and a leaf switch that you can place on the mechanical film-advance mechanism. Anyway, I wonder if the mechanism and backlight from the Kodak thing could be adapted. But that may be fussier and more ambitious than you want. But, if you capture each frame with a camera and don't want to save the thousands of files, I would suggest using a video editor (like Resolve, which is free) to render the frames out to a high-quality codec like Apple ProRes or one of the Avid codecs on Windows.

[@obansrinathan]

35mm movie film was a part of what made 35mm stills cameras affordable, as it meant people could take pictures on the most mass produced film there was, instead of the much more expensive medium or large format films made for photography that people used to have to use.

[@liselottepulver2819]

They did not use the same films though.

[@jpdj2715]

Oskar Barnack at the Leitz company started development of a stills camera for the purpose of testing movie film's sensitivity in relation with its development chemicals and process, and its characteristics at that (like usable contrast envelope - AKA dynamic range). Note that "correct exposure never was defined and even today the ISO institute does not define correct exposure with its ISO unit that only deals with "equivalence". With a standard frame size of 24mm wide and 18mm high (in the original standard 35mm movie camera where the film runs vertically), this frame size for stills was a PITA and consequently Barnack doubled the frame size for easier assessment and to keep the "landscape" orientation ran the film horizontally. It took quite some time for the concept to get developed and as at the time most "prints" (cheap) were made in contact (1:1 relative to the negative) that would not be attractive even with "double frame" (that's what 35mm full frame stills got called before WW2 in Nat Geo mag ads). So an enlarger would be needed and this complicated the making of simple prints. The advantage of perforated film (both sides) and the sturdy film (the carrier to the "emulsion" sensitive layer) meant that machines could be developed to automate the printing more easily - avoiding hand-holding by operators and associated damage to the film. Barnack built the first prototype camera(s) in 1913. In 1923 production of a preproduction series was approved by Leitz and in 1924 the "go to market" decision was made. It was introduced to the general public in 1925 at the Spring Fair in Leipzig. Part of the problems to solve before commercial release was that better lenses were needed for a larger image circle than standard "35mm" movie format, and another was how to package the film cut to a length for stills. When Leitz released the first commercial camera for shooting stills on 35mm movie film they called it Leitz Camera - LEItz CAmera: Leica.

[@liselottepulver2819]

@@jpdj2715 That is of course true. I don't know for the early aera, but later one did not just load cine film in a cartridge. The emulsions and coatings differed. Cine film has an additional protective layer that has to be removed during the process. Also you copy the film to a different film for projection. Therefore you have different requirements on the response of the film.

Thanks for the video. Great presentation about FILM. Back in 1971, while I was a student at RIT, Eastman Kodak invited our class to an illustrated lecture and demonstration about their motion picture films. In a dedicated theater with side-by-side projection equipment and screens they explained all of their film stocks and how each was designed to be used. They went through camera originals, all the intermediate duplicating films, all their different stocks, all the way down to release prints in both 35 and 16. We saw more Kodak models holding multi colored beach balls then we could stand! Then as a final quiz they projected a single screen image and wanted us to guess the film stock and process. No one got it right. It was Kodachrome Super 8. Sadly, I haven’t seen Super 8 look that good since.

If you want an impression of the true scale of IMAX... Oppenheimer is 180 minutes, 9 seconds long (10809 seconds), at 24 frames a second that's 259,416 frames. Each IMAX frame is 3540mm^2, that's a total area of 918.33m^2 for one copy of the final film. There are photos all over the internet of the film reels if you want to see just how massive they are.

[@kasperkrunderupjakobsen8200]

Yeah, they had to make extra "guide rails" for the reels holding the film for oppenheimer, as the film would not fit otherwise. As projecters have a standard size for the reels, it is not physically possible to fit more IMAX onto a reel. Oppenheimer might possibly be the longest IMAX film to exist, now and in the future. Not just the longest yet, the longest physically possible, as I don't think we'll be redesigning film projectors.

[@jonathanrichards593]

If I remember correctly, physics starts to get in the way when projecting IMAX. Projection involves shining the image on the screen for 1/24 of a second, moving the film the length of a frame, and stopping it for the next 1/24 of a second. The acceleration/deceleration required is directly proportional to the forces on the sprocket holes, and those forces exceed the strength of the film material. The solution is to have the film travelling in a wave-like motion (imagine sending a wave down the length of a skipping rope by flicking it up and down), so that each frame lands on the projecting gate, and gets shifted off again by the next wave. Again, this if from memory, so don't take my word for it!

[@HadenMadderly]

It's absolutely shocking, but the entire film is 11 miles long and 600lbs. (18km/272kg). It's delivered in 53 smaller reels and apparently takes about 24hr to prep.

[@TrackmaniaKaiser]

@@jonathanrichards593 I don't know about imax, but i worked in a theater that still aired old 35mm filmes. It's an intricate mechanism where the film itself rolls at a constant speed, but before and after the projection port you have a bit of slack on the film so there isn't any force on the filmitself! That leads to the wave like motion you might have observed, as the film comes in at a constant speed but is only transfered to the projection gate 24 times /second but at a much higher speed. Therefore the slack portion of the film constantly builds up to a larger just to be moved into the projection gate, reducing the slack again. At all other points the film is kept at a constant tension to ensure it doesn't rip! So the part of the film that actually acceleration/deceleration is always only a few inches. on a 35mm maybe 4? So I guess with 70mm 12-15?

[@TadTadd]

Edited: After seeing that folks were interested in behind-the-scenes projectionist stuff, I posted a video...kzbin.info/www/bejne/gKbXdJl7rZ6josU What a fun film/video! When you were discussing the anamorphic lenses, I was taken back to my days as a projectionist. Most lower-budget films were done in "flat" which was what you called 4-perf, with significant black bars between the frames. Big budget films were done in "scope" (Cinemascope) which used an anamorphic lens for projection to spread out the image. We had two lenses on each projector, a flat lens and a "scope" lens, on a turret. The electromechanical projection automation would run a little motor that would rotate the turret when the non-anamorphic trailers finished and the anamorphic feature began, signaled by a piece of metal cue tape. The anamorphic nature of the film is also visible in the familiar cue dots that show in the top right corner at the end of each 20-minute reel of film--they are ovals in Cinemascope films. Cinemascope films posed an interesting challenge: the frame lines were all but invisible since they used every square millimeter for the image--the thick black bars in traditional flat film (4-perf) were easy to find, but the abutted frame lines of "scope" were more difficult to see, especially in a dim projection booth. This meant that if there were a film break, we would have to go through some extra effort to find a frame line on either side of the break so we could cut and splice the film cleanly and not introduce a partial frame (that would be spotted immediately during the next showing). If the film broke during a night scene, we would have to use frame counter gadget, with a sprocketed-pulley that had frame lines on it, to go from the closest clean frame line we could find, through 10 or 20 feet of film to where the break was.

[@DLWELD]

On such splices, was the audio next to the correct frame? Or did that pose more of a problem on splicing?

[@EvilGenius007]

You should call Marketplace APM with this story for their segment "My Analog Life" - it would make a great inclusion.

[@joshuagaude6084]

@@DLWELD Audio info runs along the side of the picture and is offset from the picture by a predetermined amount. If a few frames of the picture have to be cut out to fix a break, then you may notice a small jump in the picture, followed by a small jump in the sound moments later. But because the audio track runs along side the movie on the same strip of film, it always stays in sync. Leading into the 2000's and until about 2013 when Hollywood stopped printing physical film prints, 35mm prints had an array of different digital audio formats on the stip. Sony Digital ran down the edges outside the perforations, Dolby Digital ran between the perfs (almost looking like QR codes) and DTS was a time stamp that ran between the picture and the traditional optical audio track. Since all these formats had a fixed location on the film, audio always stayed in sync regardless of how many splices are made.

[@TadTadd]

@@DLWELD no, it wasn't, but nobody really noticed. I certainly didn't think about it until only recently--the optical sound head is near the bottom of a standard 35mm projector, well below the shutter and lens, so it stands to reason that sound must lead the film scenes. And when I looked it up, the standard says that the sound leads by 21 frames--just under a second. Most movies had a few splices in them by the time they were returned to the distributor, and audiences would notice a jump and an audio click when the splice went through, but it was part of the movie experience and nobody really noticed. The cardinal sin was to leave a projector dirty and cause a film to be scratched: that would put a vertical green line throughout the entire length of the film, and at a first-run movie house that was unpardonable and many people would not put up with that.

Excellent! There was one format you didn’t mention, a large screen format that was shot on 65mm film but with an 8 perf size, shot and projected with the film running vertically. The aspect ratio was similar to IMAX but the frame was smaller, but projected films were on 70mm stock like IMAX. We ran 8/70 films at the science centre in Calgary where I worked for many years. As with IMAX, the cost of prints and shipping was steep. Films arrived on a number of smaller reels that you had to splice together to make up the final projection print. The soundtracks were on separate media synced to the film.

I still remember going to cinemas, where the shorts were on 16mm film, well worn, with the pre feature adverts always having jumps from broken film, splices, and juddering audio, along with streaks and stripes from dust and such that got caught in the film gate, and cutting through the emulsion to varying depths. Then the intermission, where the main feature would be placed on the 2 35mm projectors, or the same 16mm projector, and the gates in the projector adjusted to mask the film, along with the curtains in the cinema being adjusted to black out the main screen to mask off the edges. Then the dot in top left corner to indicate near end of film, so the operator could also start the second projector to make a near seamless reel transition. Also saw many movies on film, most memorable being TRON, where mid way through the one reel there was a jam, and you got a nice few seconds of jammed film burning up in the gate. 3 minute intermission, to splice that together, likely losing a few dozen frames of film. Did get at the one cinema a scrap of film stock, Judge Dredd, that had fallen out of the bin as it was being carried out, and I picked it up off the cinema floor.

I've taken the same strip of 800T to two different labs and got two very different results. I've also taken a stab at it with home scanning and it wasn't hard to correct white balance. One benefit of that 85c filter for outdoor shooting though is it will take a stop or two of light out, so you'll effectively be shooting at ISO 400 or ISO 200 or so, and it will save you some editing too I guess.

[@kasperkrunderupjakobsen8200]

A comment you might appreciate. Cinestill 800T is quite literally the kodak vision 3 500T stock that some of this video has been shot on, but as you say, without antihalation layer (aka rem-jet). Not just that they look similar, they are the same chemistry, from the same factory (afaik). Cinestill buys the stock from Kodak, and the iso rating goes up to 800 from 500 without the rem-jet layer. The same goes for Cinestill 400D (which is based on kodak vision3 250D, the other stock used for this video) And Cinestill 50D (which is based on vision3 50D)

[@chris24hdez]

I appreciate that you uploaded in 24p. old super8 long play has to be scanned in and edited and output in 18p and up until recently some video editing programs didn't have that output option. Thank goodness they listened to us retro preservation fans. Now the only problem is getting modern TV's to play 18p...

mesuring the film in milimiters, the frame in "perfurations" and the roll in feet. jesus

[@TheRealWilliamWhite]

Well, it is footage.

[@misterscottintheway]

Those are all really reasonable units for their use cases. You would need very large numbers to measure reels in mm and they would go by extremely fast. If you wanted to measure film size in feet you would need to use fractions or decimals. And perfs are a shorthand to talk about aspect ratios in a less technical way. It all seems complicated until you imagine the effects of trying to streamline.

Back in my protectionist days, changing lenses to fit whatever format the film was in (“Flat” or “scope”, regular vs the oval lens he showed) was a multiple times a day thing. 20 years on I could probably still thread a projector in my sleep.

[@tylerduncan5908]

For everyone joking about playback speed, since premium members dont get ads, the calculated ad revenue from premium members is (reportedly) based on the portion of time you spend watching any given monetized channel. So more of your premium membership will go towards matt if you watch at normal or slower speed.

[@Tahgtahv]

I would've assumed it was based on the amount of video you watched, just in terms of raw frames, and regardless of the speed you watched it at. I have absolutely no basis for that assumption though.

[@soarcheetah]

@@Tahgtahv It's all about watch time. KZbin just wants people to spend more time watching KZbin. Watching at normal/slower speeds or rewatching a video result in more watch time. KZbin interprets a user watching a video once at 2X speed the same as someone watching a video at normal speed and then leaving at the halfway mark.

[@ianglenn2821]

viewer retention solves this, I have one hour to watch fun math videos, that's one hour I'm spending on this channel no matter what, 1 episode or more, so I'm gonna watch them at 1.5x or 2x speed so I get more math per minute of my free time

[@juhtahel7454]

Yeah, even if it was the case that this affected people I enjoy watching, I am NOT watching KZbin at 1x speed. People speak too slowly. Alright, maybe I'd watch something fast like Crash Course in 1.5x but basically everything else is way too slow.

This certainly demonstrates the importance of lighting when filming to actual film!

[@glenmorrison8080]

Yeah, I had the same thought. The lighting in the warehouse is so uncinematic that it "doesn't look like film", but that makes me wonder how much the look of film is just the look of skilled photographers/cinematographers, who also opt to use film because they think it looks better. I suspect in an experiment testing the ability of filmmakers watching footage from a modern digital camera compared with 35, the shots with better lighting would be guessed as film, even if they were digital.

[@thewaldfe9763]

@@glenmorrison8080good point. Set design, lighting etc. definitely contributes much more to a "film look" than the capturing medium. Regarding color, texture etc.: what many people are not aware of is that a lot of what makes a film look like film is happening in the process of copying the camera negative to a (positive) print film. A scan of the camera negative itself does not look particularly interesting, so that's down to the colorist to get right.

Agreed, the mechanical aspect the delayed gratification are the best parts.

Doesn't matter what you shot it on, we're still watching it via streaming video on a device. Watching it on a film projector would be authentic.

[@Digrient]

A horizontally running 35mm process in the 50s and early 60s was called VistaVision, notably used by Alfred Hitchcock for his films of the time, like “Vertigo” (1958). It was 8-perf non-anamorphic horizontal, more than doubling the negative area per frame as compared to regular 35mm processes. John Dykstra and his shop famously revived the process for effects shots in “Star Wars” (1977).

[@Kafen8d]

I love that you can actually see film grain artifacts throughout the video. It's especially noticeable in the intro near your head, it's awesome to see.

[@Cchogan]

One advantage of film IS the cost! Let me explain. Because every take costs money, not just in the film in the camera but in processing those rushes later so you can make edit decisions (and therefore, only transfer to digital what is worth transferring), the incentive to get the performance right in preferably one take is massive. So, not only would one use cue cards or autocue, proper rehearsals were mandatory. When I worked on even corporates filmed on film (in the 70s), a lot of time was spent rehearsing the talking heads - especially company workers who had never done such a thing before. With any luck, they got it right in just a couple of takes, to produce a single, smooth sequence. Modern digital techniques mean that takes only cost time, not film. So, people are lazy. They don't spend ages rehearsing, and in consequence, segments to camera are frequently filled with annoying and pointless jump cuts. We never had those in the days before video and then hard drives. Or very few. And they were covered with cutaways. So, just the high cost of film meant we couldn't be lazy. We couldn't afford to be. The productions were carefully planned and rehearsed ahead of time, just to keep costs lower, and that benefitted the entire production.

[@MultiMatt75]

This is interesting. I've worked in TV documentary for 25 years and only on video. Rehearsal is little more than planning what people will say. Your post made me wonder if the increasingly fast cutting rate that has gradually come into screen content, was actually partly through necessity , as the number of takes grew. Aesthetics must've come into it too of course. Amazing that we are now at the point where jump cuts are deliberately added, even on a good take (especially by youngsters making social vids) to increase the visual interest

[@awesomeferret]

I bet if you read your own words out loud a few times you'll talk yourself out of your own opinion. I understand what you're trying to argue, but in the real world, if something costs many many times more, it still costs many times more. You're conveniently forgetting all the obvious advantages of being able to capture footage for free. Jackie Gleason would strongly disagree with you about strict rehearsals improving the quality of the content, and so would many other greats from the 20th century. Most filmmakers (especially comedians) would have loved to be able to film everything and build their movie on the cutting room floor. It's baffling that you think everyone would want to throw away so many opportunities. Remember, most people who make money from making videos and movies have very small budgets. You only hear about the multi million dollar movies because they have multi million dollar marketing budgets. Most people have no money or patience for film, and you seem knowledgeable enough to know why.

[@wolfgang4593]

This was also true in for home/vacation movies. I remember the agony to sit through the hour long VHS vacation video of a relative who was the first to buy a video camera. Up until then, he had super 8, which had only about 3 minutes run time per cartridge. They weren't that cheap and it was a hassle to splice them together, so the vacation videos were rarely longer than 10-15 minutes, much better suited to his limited story telling abilities. With super 8, he had to carefully choose what to film. With VHS and no equipment for video editing, scenes that should have lasted 5 seconds went on and on for minutes.

The difference between 16mil and 32 mil is the same as SD (720x480) to HD720 (1280x720) to HD1080 (1920x1080) to UHD4k (4096x2160). It's like exactly one step down. That's so cool!

[@andrewparker318]

Oh my goodness, the soft colors and detailed highlights just look so much better on film than on digital! I really hope this isn't the last time we see a KZbin video shot on film, because it just looks so much better than digital in my opinion

[@simval84]

Today with post-processing tools, you can adjust film and digital colors so they are almost identical. The one difference the technology will always provide is that film shadows are deep, with no details to recover, but highlights are almost never blown out, you can always see details in them. For digital, it's the other way around, clipped highlights are gone forever, you can brighten shadows and recover details in a crazy way.

[@OMC1109]

Shadows are lost and highlights are recovered if you use negative film, if it is positive it is the opposite and works like digital film. In my opinion there is something in the depth of the image that seems better captured on film, the diferents planes change more organically, without the "collage" feeling that the excess definition of digital has. But it's subtle, not so noticeable. but we must consider that we are seeing it digitalized and on KZbin. A good analog copy with a good projector increases the image quality a lot. In any case, the digital format is a blessing due to production costs.

[@AnasHart]

That is the first time I have seen a video that explains all of these concepts in one video. So well explained. I didn't understand the 4-perf concept, but thanks to you I do, now. Thanks. And it looked great on film - quite different.

[@scragar]

One weird advantage film had over digital is it hasn't aged as badly because as long as the original film is undamaged you can recapture it to upscale up to the resolution of the film. This means some films originally recorded for VHS have been able to be converted to 2k bluray without looking terrible because the original data was still there in the film reel.

[@dkamm65]

An excellent example of this is the music video for Last Christmas by Wham. Most of the the original film was found and digitized with modern equipment, and the video was recreated, edit for edit, in 4k. It looks unbelievable.

[@Yetaxa]

It actually means you get the strange situation that there are movies 100 years old, like idk, The Wizard of Oz or Metropolis, shot on 35mm, that could be transferred comfortably to 4K, whereas some films shot early on in digital HD, like the Star Wars prequels, are limited strictly to 2K, a lower resolution than these much older movies.

[@TheDuckofDoom.]

Star trek TNG used 35mm to acheive a more cinematic feel, and has bright crisp detail even on modern displays (It even looked pretty good after being transfered to video, broadcast, and picked up with an antenna for analog CRT); then Deep Space 9 which overlaped TNG by a season used an analog video camera like most sitcoms and it looks like a terrible smudge regardless of the display equipment (Not just cheaper recording, but it helped cover the lower budget costumes and sets).

[@doublepinger]

@@TheDuckofDoom. More Star Trek nerd-er-y: The Original Series and TNG were recorded on film, but DS9 and VOY were on tape, or at least, post-production was kept, on tape. With DS9, there's a lot of CGI mixed in which makes it difficult to upscale, and with VOY, there just isn't more detail available. It's strange TOS can be exceptionally crisp, but stuff shot 30 years later can't...

[@Appletank8]

also based on how much an industry cares about preservation. like old episodes recorded on VHS being the only copy because the original tapes got written over.
