How Was Video Invented?

I always wanted to know why film looked better than video. Moving electronic images have as long a history but were invented for a different purpose. This video was sponsored by B&H Photo:

This is a video I've long wanted to make, about what makes video look like video and, up until 10 years ago or so, not as appealing as film. I grew up with the two technologies (film and video) in parallel and to me they always seemed like two ways of achieving the same ends: recording and replaying moving images. But their histories are quite distinct. Film was always a way to capture moving images for later replaying. Video started out as a way to transfer images from one place to another instantaneously. This dates back to the first fax machine, mechanical TV, live broadcast tv and ultimately videotapes. This history focuses on the early decades of video and not the more recent switches to chip cameras and solid state storage. Maybe that's a story for another day.

If you're watching this right now, it's probably because I posted a gif in the community tab. I'm curious if you: a. have seen the video already b. didn't know it existed and the community post is the first you heard if it c. saw the title and thumbnail before but didn't click it d. other?

People are using digital because it is easy and cheap to use not because it is better than film or it is in on it's own but you got the point.

Thank you B&H . Straightforward to the point . this is exactly what I like . do you have videos about vacuum tubes ? what does it do to society you're asking ? rude awakening that is what it does ! life is what you make of it and the good that came out of this technology Trump's the bad , what a wonderful things to get in touch with your fellow human beings and get to know how they live , what a wonderful thing it is for technology to make us feel the happiness and pain of Our Own fellow human beings on the other side of the planet , though they are on the other side of the planet what I say is to do good within your Arms Reach, eventually it will get to the other side of the planet , maybe if we know more about each other we wouldn't be killing each other as much .

It's not as though, after almost 60 years of recorded audio, people in television were like "nope, we just devised this as a way to send live content" -- you danced around the real reason it took until 1958 to record video electronically, and the reason those tape heads were spinning at 14k RPMs: bandwidth. Video requires *a lot* of bandwidth. Coaxing a physical medium into storing that much information requires speed and precision that needed to be developed. And it was, because humans are total space babes.

You kinda forgot Ernst Ruhmer who used selenium cells in 1909 to transmit live changing images from Brussels to Liège (115km). He wanted to showcase a more advanced system but the price of the selenium cells at £ 15 each, and needing 10,000 of them, made it too expensive and he couldn't find sponsors. The other thing you skimmed over (probably necessarily) is that the first CRT's were invented in 1897, called Braun Tubes. But only by 1922 the so called hot CRT's were invented that made displaying moving images more practically feasible.

It should've been mentioned that the Nipkov disk was also used for early video calling around 1928. DIY kits existed for hobbyists to build such devices. One such is displayed here

On the other hand... It sometimes gives me the shivers when I imagine that there are interests out there in the real world which - without hesitation - would put an entire species into a test tube... It's beyond my reasoning to tell where social engineering will bring us to. But I think that the development of the technology shown to us in Dereks clip speeds up the process.

In fact Lordy (x "The Algorithm" x) brought me here coming from there: (8 maybe because my click behaviour or my comments suggest that I somehow like both of you very much 8) What brings me to a suggestion for the answer to the question you asked within the clip... I think that in combination with the state ot the art computer technologie today the availability of high quality video standard we are given access to is giving our society one great feature... To calculate our average social behaviour by summing up the every day responses of each of us according to information input. [ Berechnung unseres durchschnittlichen Sozialverhaltens durch Aufsummieren der täglichen Antworten jedes Einzelnen von uns anhand der eingegebenen Informationen. ]> (x just a quick check via feedback loop if my english has improved x) ... Wich is, if you ask me, a big deal. (8) LG & 42!, muck(8)

Very nice basic explanation but one big problem .. you left out the most important part .. the inventor of the electron gun- Manfred VON Ardenne , a self educated genius.. I’m biased I work for the still family own / run company - that’s a big gap in your basic history or Video’s not hard to look him up, unfortunately his accomplishments were also left off my Engineering education , why cause he was living and working in east Germany during the Nazi era

I wondered how TV screen pictures were stored for replaying. Now I know! Now how was the opposite done. How did a movie on film get broadcast onto TV? Did they project the movie onto a screen and point a TV camera at the screen?

The image pickup tube worked. Not by reflected light,. BUt rather the varying current from the cathode to the anode or target. The first video tape machine was in 1955 by Ampex. I worked on those machines thru 1990. First editing was done by physically cutting tape. And has evolved drastically. Fun fact: the word VIDEOTAPE is copywrited by AMPEX. RCA called it "television tape" The video heads did spin at 14,000 rpm but was soft high pitched sound. The video heads revolved on a cushion of air by way of an air bearing. Ball bearings created a very nasty vibration that wore out quickly and produced artifacts in the video signal

Im from the future when people can share every part of their life with video. There is this thing from a dystopian science fiction novel called social media which purpose is of bragging and benefits people with good income and genetically symmetrical faces. United states have conquered the world with its cultural imperialism. Individualism is the new religion and the world produces its energy from narcissistic younger adults.

4:03 I thought early CRT TV used odd and even lines when scanning (interlaced scanning). This was to stop the phosphor lines, interfering with each other and becoming to bright from excitement. Later progressive scan came about, and scanned like the video segment showed.

When I was a kid and the first time I heard about the word "Download" a thought came to my mind that maybe they use one device (screen) to display a video and other (camera) to download (make copies) it... And maybe same thing happens with audio and photo downloading process.. {I'm talking about mobile phones in second half of 2000} *“Damn !! it was real back in 50s..”* 😁

Great segment ... I still work on vacuum tube equipment in the music industry. Some small companies still make gear with it, microphones and preamps as well. And then there are whole audiophile people who love and use them and design them still to this day. Tubes have a warm color to their sound. Even some broadcast stations still have to use them as nothing else can handle the power levels needed for high power antenna transmissions,, So I think there will always be a place for them.. i'm designing a new DIY microphone with them myself.

This missed allot of points when it comes too how cameras and video were created bc ppl dont understand the fact tech has been around for allot longer then what there told lol...for example plenty of times he said they used electrons too scan something but did not explain how its scanning and saving for them and so on theres gov secrets when it comes too development of technology from the beginning and this is 1 of the main steps for PCs being created

Honestly it's pretty cool how we are able to create weird hacks that are basically illusions that only work because of the quirks of our biology. Like imagine if another sentient species in the universe has eyes that are not fooled by the whole "rgb pixels" thing, would they ever figure out a way to invent television or computers? How would that effect their society?

I highly recommend the documentary Side by Side, produced and narrated by Keanu Reeves. It explores the evolution of cinema cameras (from film to digital) and ponders the question, "Is film dying?" With interesting interviews from world-famous directors like Martin Scorsese, Christopher Nolan, and many more, this documentary is a wonderful examination of film cameras today.
