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: www.bhphotovideo.com

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.

My father, Sam Holtz, was a legend in broadcast television engineering, telecine, and video post production. He filled my head with all this engineering science and history over the course of most of my life, along with all these technical inner workings you described... just about all of it now a lost art. I watched this video with a deep appreciation for you. Thank you for bringing this knowledge to a new generation and doing it so accurately. I just wish my dad was still around to have watched your video. I know it would’ve put a smile on his face. Peace.

I think it's imperative that 20th century ingenuity doesn't get lost to history. The 20th century was special, in the sense that it was a time of transition. Before the 20th century, the things we invented lasted for centuries, so we have a lot of time and examples of each tech we used before that time. We won't forget about horse shoeing, or water mills, or traditional swordmaking, because they were done for millenia. The things we do now in the 21st century, each lasts even less, but there is better tech to document each (the internet doesn't forget), and they are built in more straightforward ways. We don't do 4k video in a different way than we do 1080p, or 720p, and we won't do video in a fundamentally different way centuries from now, it'll still be pixels stored and transmitted digitally using a certain format. But in the 20th century, we had just enough tech to do crazy thing, but not enough to do it in a straightforward way, so we had to get creative. And each of those techs was unique, different from the previous one, and lasted for a short enough time that we might just forget about them. In the past 20 years we went from 240p digital video to 360, 480, 720, 1080, 4k, 8k ... basically the same tech, just different quality, codecs, etc. The same for audio. Meanwhile, in the 20th century, we jumped from cylinders to vinyl, to 8-tracks, to cassettes to CDs. From 16mm to VHS to vCDs. From the telegraph to the telephone, from rotary to push button, from analogue over copper to digital over copper, to VoIP. From massive bricks to flip phones to smart phones. All in such a short timeframe. As you said, lost art.
Chickenbread 年 前
It's interesting to know that high quality 35mm Film has about as much detail as a 4k Video. The reason most movie studios waited so long to switch to video is not because they waited for better editing techniques, but more because they waited for Video quality to catch up with film quality. That's also the reason why some older Music Videos can be remastered into good looking 4k, but some newer ones can't, the latter being shot in Video. Even today, some movie directors opt to shoot on film, but 70mm IMAX often, rather then 35mm...

Yup. Film reproduces color more accurately too. This is why older movies tend to look very vibrant and almost overexposed, and newer movies look cooler.

+Kalvin Halvorson No, they didn't figure this out from scratch, they built on previous knowledge, it took more than century worth of Engineering and creativity to get to where we are today. Cathode Ray Tubes were not originally invented for displaying videos, but, some Engineer or Physicist figured out that you can use it to display images on a screen. So, you take an invention already made by another scientist, and you add on top of it, you don't make it from scratch. And you work with a team, not by yourself, because it would be near impossible for one person to figure all this out on his own. And i know this because i'm an Engineer, and it's all about team work, and building on previous knowledge. Even today, most technology you use may seem futuristic, and advanced, but it's no different than the technology from the 80's and 90's, we have just gotten more creative in how to better design and manufacture it.

Having touched on the Nipkow disc, this would make a great segue into spinning-disc confocal microscopy. It's basically the same technique being used today to create some of the most advanced real-time 3D biological microscopy images out there.
If human population dies out due to some worldwide catastrophe, human knowledge about things such as Derek's videos must be protected at all costs.

Excellent presentation !!! I grew up in the 50’s and 60’s. By age 13 I was riding my bicycle, with western flyer wagon behind, going around the neighborhoods collecting discarded TV sets. I would take them home, remove the tubes take them to the store and test them, and use the good ones to replace bad ones in other sets. Then sold working TV’s in garage sales. I can remember when fast moving TV images became less smeared when the vidicon camera tubes were replaced with the new plumbicon tubes that had a faster response.

Such an excellent breakdown of the history of video. The balance of the technical aspects and real world implications of video w/ examples made this "video" both interesting and educational. Also extra points for noting how this ties into You"Tube" and the Emmys. I've always enjoyed this channel, but this was the video that made me realize I wasn't subscribed yet, so now I'm sub'd.

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.

IIRC, the fact that storing video was difficult meant that a lot of famous TV broadcasts have been lost, even after recorders were adopted. The early episodes of Dr. Who were taped over for later programs, and now the only known recordings are audio tapes made by a viewer. The moon landing footage was also taped over by NASA, so the only existing footage is a video recording of a video broadcast of a video broadcast.
Dom C

Key thing to remember is that it was a cultural decision as much as a technological one. The mindset was simply that TV was one and done, like a theatre show. The idea of keeping the early episodes of Doctor Who for posterity seemed inane to most people at the time. That said, taping over the moon landings is pretty ridiculous!

I remember learning in my history of mass comm class in college how every episode of I Love Lucy you see was recorded by a film camera aimed at a TV. Also, one of the fathers of CRT, Vladimir Zworykin, became so disillusioned with how television changed society that when asked late in life what he felt was his greatest contribution to television, he said "the off-switch".

Cathode ray tube TVs must have seemed so futuristic and advanced when they first came out. Before that the only moving pictures people saw were from film reels and home video. To actually get a live image beamed into your house would have been insane, and was crazy expensive too, people used to invite their poorer neighbours round to watch live events. Now I've got this little screen in my pocket which unfolds into a bigger screen and has immediate live access to virtually every book, movie, tv show, radio station, song, album, technical paper, rolling news, piece of art or guides and instructions ever created. Oh, and I can use it to speak to pretty much anyone on the planet. We are living in a crazy science fiction future and it all seems perfectly normal.

Your last question in the video "What affects are caused by everybody being able to share, with the public, anything on video caught my attention. I would say it has become very difficult to tell the difference between what is real and what is fake; why, because in addition to everybody being able to share everything, they can dramatically alter what they share by using software.

A technical correction for the graphic animation at 4:15: The coils are swapped. The coils driving the side to side sweep are actually the top and bottom coils, and the vertical sweep is from the side coils. The force imparted on the electrons is at a right angle to the magnetic field its travelling through. (Being also at a right angle to its velocity.)

Great video. I am an electrician and during one of my classes, on data systems, I asked my instructor about the television, I don't remember his exact response, but I know it wasn't satisfactory. So went down the rabbit trail. Anyway, its fascinating what transitors have done for the world of electronics. I would love to see you do a video on the history of video transmission. Especially because of the patent wars that ensued over it (the first actually was a man who had the idea as a boy).

I always find it so interesting how creative old technology was. It blows my mind how CRTs work. The digital versions of everything seems trivial to understand for some reason.
Probably because digital versions work on the electron level, something we can't see or barely imagine. The older technology is much larger and it's easier for us to see the process actually happening.

Cool video, I especially liked the early history you included covering scanning. As an Englishman married to a Scot I waited for the menion of John Logie Baird who actually built a mechanical disc scanning TV system for the BBC before WW2, but I waited in vain. That early but ultimately futile attempt deserves its own video, and I have no doubt there are a bunch of them here on JPvid. All the same I could not help but feel a little sad that you did not refer to the eccentric John Logie. If you're ever in Glasgow there's a working Baird setup in the Science Centre. Did it work? Yes. Did it work well? Of course not!

Is that what happened?? Is that why his shows have been so weird? Did the psychedelics get him?

Ahhgg, that Vsauce host is so irritating. Keeps jumping all over the frame. So distracting on topics. :3 Veritasium host is great! Simple and eye shooting and easy to be pace with him. :)

I knew most of this but it was superbly explained! Some people mention you didn't give credit to this and that inventor but then your video would last 3471 hours at least!

Dude, I never thought it would be that complex, I don't understand 80% of the video. I ABSOLUTELY LOVE IT!! Also that voice crack at 4:28 had me laughing for a bit. Love your videos man, you're the best!!

Please, don't sell yourself short. I'd bet that if you really didn't understand 80% of the video, you wouldn't have bothered to put a comment in.
This is so interesting. I remember when televisions had tubes in them and the 7-Eleven had tubed testing stations!

Great. I always wanted to know how analog video was transmitted and why until certain moment there was just live TV.

I saw one of those first series Video Recorders in NZ belonging to a Television Studio and on loan to Youth for Christ for a training aid. It was cutting edge back then … now it’s nothing to record on my iPhone and wirelessly send it to my TV or the Internet. Those Tape cassettes were pretty massive …

If I could travel into the past, I'd go back and demonstrate smartphone video recording to the Ampex engineers who developed the first video tape machine.

My first job almost 30yrs was running 8 huge projectors at a movie theater. I can still hear all those sounds and smell those smells. It was awesome!
I hope you make more follow ups on this topic. The younger generation does not know the gargantuan efforts of the engineers in developing the current technology for image processing. Not to mention the strain it placed on the general populace. 1. The issues of keeping backward compatibility at each step (including black and white to color) 2. The format transitions (VHS vs Beta, CD, DVD, Blue Ray etc) 3. Aspect ratio change ( 3/4 to 9/16) This video is a great start. A great fan of you.

Knowing now that film was better than digital video for nore than half of my lifetime, makes me feel old, but also excited to see the rapidly increasing pace at which technology is improving, I even remember growing up with VHS and listening to vinal for a short while and then CD's that were recordings of the vinal records my parents had, and now I am typing this with vertually a wireless supercomputer, while laying on my bed. I'm 19, thanks for making me feel like 4 times older than that😂

You might have omitted the PAL part of the television because it would confuse people. But for the completness: PAL has a resolution of 625 lines and works at 50Hz (25 frames per second interlaced) Matt Parker has a good video about why NTSC is 29.97fps ;)

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 en.m.wikipedia.org/wiki/Mechanical_television.

The fact that they knew how to do this way back then makes me wonder what they are not telling us and do I even want to know 🧐

To answer your question, Derek, of "What does this do to society?" The ability to easily film everything about their lives, anytime, and instantaneously publish this video to the public is, it made society addicted to attention. It's created a pandemic of narcissism.

Can you imagine.. "Gather round, family! Time to fire up the color-picture tube!" *switch clicks, relays fire, belts and color wheel spin up* *shouting* "SO WHAT DO WE WANT TO SEE TONIGHT?!"

More like wait 5-8 minutes before it warms up then reboot it and it will show picture.

Don't forget the rabbit ears! Sometimes one of us had to stand just right next to the tube to pull in that one station.

That's funny, because DLP projectors have always used a fast-spinning color wheel (but with more colors and faster), and cheaper ones still do that, and this is the reason when you're seeing an image from one and move your head, you temporarily see a faint rainbow.
naota3k 4 年 前
@Nezumi-sama Wow really? I've definitely noticed that weird rainbow when moving around, never knew what caused it.

My dad always called TV "electric TV", and now it makes sense, he was born in 1937.

The Goldmark spinning disc was used on the moon to return color images without extra electronics. Also, Samsung and other companies built DLP projector box tvs in the early 2000s to display HD 1080i and 720p video. A major component used in creating the color display was a color spinning disc setup the light went through prior to hitting the screen. Made beautiful video. John Logie Baird created a large color set in 1946 using the spinning disc technique. GOLDMARK was at CBS and they were first to release a color TV system in the world. It was stopped by NBC bc it was not back compatible to existing b&w tvs. They used the war production act to stop CBS during the Korean War. This gave NBC/RCA time to finish their compatible color TV standard for NTSC.
