YES!! Being reminded of things I know - but have forgotten HOW to EXPLAIN! Thanks for the lessons.

the best by far tutorial on audio!

I have not followed this discussion so I don't know if this was addressed. I was involved in cognitive research in the early 70's. So, I asked copilot, "how long does it take for an image to get from the eyeball down the optic nerve into the visual cortex?" The answer, "how long does it take for an image to get from the eyeball down the optic nerve into the visual cortex The journey from the eye to the brain is remarkably swift. When light enters your eye and hits the retina, the information is converted into electrical signals. These signals travel down the optic nerve and reach the visual cortex in the brain. This entire process takes about 13 milliseconds. It's incredible how our brain processes this information almost instantaneously, allowing us to perceive the world around us in real-time. Watching Gemini Man at different frame rates objects disappear at 30 fps that are visible at 120 fps. When the motorcycle speeds past a light pole, the blurred light pole is visible at 120 fps but invisible at 30 fps. The darkness between the quickly moved mouse example you showed demonstrates how detail is lost at low frame rates. It is a subjective opinion as to whether traditional limitations are as good as to what is currently available. At times I shoot golf swings. With some new gear I began exploring 1K 240 fps golf swings. My latest camera can capture 1K at 240 fps to the internal CFexpress type B card. But my Atomos recorder only goes to 120 fps. An old camera delivered 900 fps on a reduced size image. I got some incredible video of how a golf club head behaves after impact. A radar tracking company uses a Phantom camera turned down to 20,000 fps the frequency of its radar to sync radar reflections to physical reality to understand the reflections . So, your discussion of fps in a theater just scratches the surface of what is currently possible. Are you recommending that we go back to rotary dial telephones?

Beautifully explained! I worked in a TV station in Wales, and when the subject of NTSC came up, I was told that everyone knew it stood for "Never Twice the Same Colour".

I was surprised I was able the hear the difference between waves A and B. Didn’t sound like a square wave but two sinewaves of which the other one was some what painful

I think that the 24fps will stay but if the 60fps are accepted too i think there will be an option to change that because not all people like 60 fps maybe only for videogames.

I absolutely hate these high fps movies. It's the worst thing to happen to the industry. Not every increase = better.

Thank you so much for all your time and effort that you put for making this educational video. It will help me with my homework and final. Thank you , Thank you.

I remember reading that PBS used to air It's a Wonderful Life before NBC got the TV rights to the movie.

Thank You

John, Any reason why you couldn’t use this Hollyland portable kit for live amplification applications such as micing a keynote speaker or solo entertainer through a PA? Would it work just as well as a similarly priced consumer level wireless system? Thanks

I recommend the Forbes article called "Spotify Wrapped 2024: Backlash, Controversy And Memes". It's perfect!

epic video, thank you for doing this

Hlo john sir how are you . john sir as you said that readout speed is very fast in rolling shutter so sir because of this much fast speed we do not see any rolling shutter effect in our human reaction like when we record ourselves we see exact reaction what we gave like while talking in camera we even cant perceive that our face reaction becomes in different moment of time and even when we run with camera in hand then also we do not see difference in our reaction. So john sir we do not find that our face reaction is captured in different moment of time so sir we do not see it because read out speed is very fast? Am I right sir ?

Thanks for the explanation! In pre production, who typically decides on the synchronization system to used and includes it in the equipment order? And on set, who is responsible for operating and managing it? Would it usually be the producer, the DP, the sound mixer, or someone else?"

Fabulously done John ... incredibly well explained. Thanks so much for this 💚🙏😎

You have said 1976 "A Star Is Born" & showed Judy Garland version of 1950s.

Have been viewing your videos since last 4 years, inspiring and full of top stuff....keep it going. I am just starting on small videos of scapes bht sticking to 1080p, am i in stone age or its ok😊

Many thanks for this extremely helpful video. Thinking in terms of ADR as an option where sound recording could hold back the flow of a production is liberating!

I LOVE YOUR CONTENT!! But … is this really a necessary topic? *YOU USE MULTIPLE CAMERAS* you’re all welcome. Lol 😝 sorry it just feels… kind of like asking, “how does 1 start a car?” Well… with the key, sir.

A legend that eventually gave us Fox News and Fox Sports 💯💯🙌🏼

What do you think about compression? What is the normal lens regarding the compression of the human eye?

I saw someone say that Wicked is the best movie musical about a green individual dealing with prejudice since Shrek 2.

Wicked is being well received in general, critically and in the box office. The biggest criticism is the cinematography.

Paramount has been struggling to compete for the past decade because Viacom (2006-2019) was the smallest media company in the industry, even smaller than CBS before merging back with them in 2019! Viacom was too small to compete with the other companies because they took the cable networks (MTV, Nickelodeon, Comedy Central, VH1, CMT) despite the industry dying by the 2010s, holding Paramount's investments back, not to mention the Star Trek hiatus with Viacom and CBS Splitting the rights until 2019. even after the ViacomCBS remerger and rebranding to Paramount Global, is still the cheapest company in the media industry, making bank with CBS, SpongeBob and South Park alone while the 2 franchises home cable networks are on life support. Paramount+ technically isn't even a new service, its just a rebrand for CBS All Access with Viacom content added. the Redstone family are clearly not fit to run this company, its literally one of the things Succession on HBO was mocking with the ViacomCBS Merger. hopefully the Skydance merger will fix this company, but if i were in charge of Paramount, i would divest from the cable networks that have become irrelevant, expect for Nickelodeon, they gotta keep SpongeBob around for as long as they can, because he's their mickey mouse cash cow!

I missed it

I really hope you watch that Moviewise video I talked about, I would love your in-depth thoughts. One more thing: Kurosawa liked to write his screenplays with at least one or more people. He said that as a director, your first instinct is to write not what will be better, but what will be easier to direct. Kurosawa believed that collaboration with other writers was a good way to avoid this pitfall.

you are a dumbass for hating lalaland, unsubscribed, man of no taste, dummy, dummy

And how does that make you feel?

I think this video will age poorly. The change to 60fps will happen slowly over time, driven primarily by new generations tastes. It's no secret that youth today watch films less and less, and spend more time with streaming, gaming, and shorts (most of which is packaged as 60fps). As more limitations in technology continue to be less of a problem (data sizes, bandwidth, etc.), the market will do what the market does best.

If cameras have super sensitive sensors to shoot at say 1/20000 to say 1/100000 to capture objects with no blur or very minimal blur, frame rate is less important. Maybe in the future when data crunching is no longer an object, video will be recorded in a whole different way, maybe each pixel will have its own video signal and in that case frame rate will be tied to the frequency or sampling rate of each individual pixel signal.

At 12:15, one point that could be important regarding frame rates of a given camera is when one needs the exact value as a source for calculations.

I use a specific GoPro camera firmware feature to film in 24 fps exactly because the compresssion tricks on my smartphone always has it be a little more or less than that.

I just want to know who the fuck at Fox always cancels my favorite shows before they even get a chance

Great video, great work, thanks.

When they turned on the color in the 1960's TV. Guide would indicate that a TV program was in color by simple saying COLOR. We bought a new guide every week to plan our color viewing. On Sunday we went to my Uncle Lloyd's house because he was the first to purchase a color set. This worked good till Aunt Dot got her vacuum cleaner too close to the set a scrambled the color, they had ta TV technician come out and degause the screen. Later sets did need regausing due to new technologies. My friend Terry N. Collected every early TV guide. He had lots of weird collections. 😂

Thank you for this! You explained the concepts incredibly well

I know I’m in the minority, but I HATE directors who don’t write. I’m a filmmaker, and I’m a true filmmaker. Directors who fail to write are lesser filmmakers. A filmmaker must be a director AND a writer. Directing and NOT writing a movie is dishonest. You claim a movie as your own but you’re stealing someone else’s story. Very few directors would ever be deemed auteurs by most people anyway. What I find annoying is when some video makers credit directors when citing movies in their videos, particularly documentaries, even from what you might call “lesser filmmakers”, ones who aren’t very well-known and who are just hired guns, as I think just about all directors are. If you ask me, directors, most of them, including myself, can be changed and the overall product will only be slightly different, inasmuch as for one who watches enough movies, the same principles apply. Sure, there may be variables between directors, but they are not sufficiently unique. Even, I’m not that unique either. In fact, I like to imitate movies. But directors are irrelevant when I watch movies anyway. Actors, characters, years, sometimes studios, are all relevant to how I analyze and judge movies. Also note, how I rate movies, or any art or fiction for that matter, goes thus; a good movie is a movie that I like and a movie I don’t like is a bad movie. Same goes for music, tv shows, and so on. Pure and simple. Now of course, there will be people who dismiss my attitude as “simple-minded” or “relativistic”. Would anyone be offended if I were to say a movie like, say, Schindler’s List is a bad movie? I would because I hate it. But there are way more movies I could call “bad” even if it’s not socially acceptable to do so. It wouldn’t make any sense to say “Seven is a good movie but I don’t like and won’t watch it again.” Sorry, but you can’t and shouldn’t separate taste from quality. Goodness and enjoyment go hand in hand. If you like a movie, then it’s a good movie to you. That’s all that matters.

A correction: 32 bit float and 32 bit fixed have the same number of possible values, but float can represent a larger (and sparser) range of values. There's only ever 2^32 possibilities if you have 32 bits, so you can never represent more distinct values than that with 32 bit.

2:30 "a bite is a number of bits to express a character" This is one common view on it. Another POV may be expressed like "a minimum segmentation of memory used in computer logic". So, actually, there may be any information stored in bytes, not just characters.

Could you do one on universal?

You should the history look like Universal, Columbia and Warner Bros

Can you do an origin story video of Warner Brothers Pictures and New Line Cinema?

John sir I read about pseudo global shutter in cmos as they use trigger .so sir I read that now in most cameras pseudo global shutter came to avoid rolling shutter distortion .is it true sir as this pseudo global shutter capture image at once or sir this pseudo global shutter is also like rolling shutter. Can you explain sir briefly about pseudo global shutter

awesome

none of my xlr connectors have that single metal clamp for the insulator.. I just have the seperate plastic clamp.. i think I like the looks of the metal clamp design a lot more

i have been editing video tape since it was invented. I used to physically cut the 2" quad tapes, and have used, i worked on the Editec, EECO and CMX systems. 29.97 fps is because of the introduction of color video, otherwise B&W video was 30fps or 60 Fields/sec

Have you seen the news that the upcoming Sonic The Hedgehog 3 film was shot on 48fps? It's still unknown whether it will be released in HFR, but worth paying attention.

I have two kinds of headsets, one set that covers my ears and blocks most all the outside sound, and one that has small foam covered speakers that don't make my ears sweat. Those are my priorities. :)
