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.

It's insane to me how they even figured out how to 'shoot an electron' let alone shoot a beam through a tube thousands of times a second across a reactive chemical to produce an image 🤯
While it has been phenomenal, I think he's centering too much on himself. Too much of Veritasium logo's and Derek in the video. I come here to listen to scientists and ideas of science. But this was a History video so I guess for this one, its fine. Hope you do rectify later though.
And sometime in that history, a bunch of people with slide rulers put men on the moon. Calculators didn’t exist yet. What percent of the human population is just being carried around by geniuses like these?
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?!"
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.

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...
Film means the old physical way of storing/making videos while video in this case means digital way of creating/making videos. So an analog camera uses film but your phone is a digital camera.
Mechanical TV for the masses! All power to the vidicons, image orthicons and iconoscopes! From a Labguy and Veritasium fan: thoroughly well researched and executed. Thank you.

It's awesome how you describe the history so succinctly yet comprehensively, and at the end you challenge us with a relevant question about how all of this technology influences us today. Great content, please keep making more!
That's exactly what I thought! CRTs don't have pixels :/ Alec did a very good job of explaining this subject in-depth, but I'm sure Derek's take will be easier to process for those not technically-inclined.
Derek, I enjoyed this show. Quite interesting to get a wrap up on film and video, as I lived through this period since 1953! Great to see how it was done after just being on the receiving end most of my life. Also I got involved in acquiring and editing video in the mid nineties. Oh, I also enjoyed your show on the wave pool, that is so amazing! Thanks for everything!
I remember those old AVR1 2” video recorders when I started in television. The heads were suspended on air bearings because mechanical bearings created bearings created too much time base errors. Also the capstan driving the tape had negative pressure to suck the tape onto the cylinder... then came the exciting time of rewinding the tape. Because the capstan was committed to driving the tape it would spin at many thousands of RPM, a break in the tape during rewind could be lethal so operators had to leave the room. You could hear the machine rewind many buildings away. They cost in the order of $250K back in the day. Now it’s so easy and cheap with fast digital electronics.... luxury!
You're TH-cam's best quality content maker. And I was wondering about this topic a week before and just forgot about searching about it. Thank you man.

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.
I don’t see how everyone just goes about their day to day life not wondering how electricity works. Let alone subjects like this. I’m so glad I chose to go to college and choose a career path to mess around with awesome things everyday. I remember my first couple of semesters of college I thought I was learning magic.

Most people aren't. The crazy thing about humanity is that 95% of the population just makes sure that the species survives. The last 5% actually innovate new technology to share with their tribe. In our case, our tribe being the planet.

The Algorithm doesn't select for quality, informativity, etc., just click-through-rate. It does what it does. Is a plant wrong if it grows good looking but bad tasting fruits? What about the other way around?
@@StainlessHelena that's actually not true. The algorithm accounts for a lot more than just click through rates, like watch time, likes vs dislikes and the amount, also whether those clicks come from a different website or not.
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.)
Wow! This video blew my mind thrice! I was looking for information on how recording was done, or rather how images were encoded onto magnetic tape in VHS cassettes. BUT, I haven't found it! I guess this would be a great theme for a new video!
Actually it was simpler the problem is we don't appreciate today's technology enough and we think it's simple but if we go deeper in to how things work its so complicated
@@elypowell6797 because it's interpreted as saying that those things could not be invented by someone else. Don't focus on the people, focus on the ideas. It's ideas and solutions that make a species survive, not the knowedge about the individual.
When the iPhone came out with its minimal, intuitive interfaces a lot of its fans wondered why other companies hadn't had the idea of just keeping it simple. These people do not appreciate that, in fact the simple feeling interface is often the much more complex system. Simple interfaces are not eliminating complexity, they're managing it for you.
Color CRTs do have pixels in a certain sense. They have RGB phosphorus dots lined up in a grid of triads. But instead of a circuit that activates them it is a cathode ray.
I'm a little surprised as to why you didn't talk about how modern-day TVs work or touch base on how plasma TVs work. It would be very interesting to learn that from you. Almost every video that you make, I understand and love it. Keep it up man.
Fun and interesting video altogether. Also, I loved how the ending made me think of the time when Fred bought a new bowlingball for Wilma as a christmas gift ;)
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".
Richard's obvious passion for video is endearing. I've watched Technology Connection's videos about this subject, and this is a very good compliment to it.
Thing is, the election gun is NOT so accurate, that's where the "shadow mask" comes into play to make color CRTs work. This also means that the colored phosphor dots are not pixels as mentioned in the video. Technology Connections has a great video on the topic, check it out if interested to learn more. I may be hard on the Veritasium guy, but he named his channel "an element of truth", so glossing over the fact that the shadow mask is what makes color CRTs work is a pretty big omission IMO.
@@Δημήτρης-θ7θ and you forgot to mention the deflection coil ,which Is what guides the electron beam to the proper position on the back of the phosphor coated screen.
Amazing video, it was really interesting. On a side note, I would have liked the inclusion of the engineer Guillermo González Camarena and his contribution to the color tv
Great video. I never thought I would shout out a sponsor in the comments, but B&H is no joke. Actually, shopping there is kind of an experience. Cool place with the best service out there.
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).
He is absolutely amazing. I highly recommend anybody with even a slight fondness for CRTs, television, laserdisc or video tapes to check him out on youtube. He has really good videos on CDs as well, all with in-depth explanations. One of my favourite youtube channels.
OMG! Where have you been all my life ? Dude, I'm 30 and starstruck . Back in the 90's we had a cathode tube one. This video is so meaningfull and relevating to me. Imagine our grandchildren accessing this clip in 2050's , using some Cerebro-ish implants to their cortex, having it projected to the retina. Sheeeesh! See yall in the 50's, folks! Stay safe! Thank you so much for the effort of putting this together!
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.
Image burn in still happens in modern sets, in fact it is a even greater problem on 4K OLED sets than it ever was on CRT sets. A friend of mine who is a TV technician went to a conference put on by one of the major manufacturers, Samsung or LG, I think, and was told to tell customers to limit viewing of content with static imagery including sports telecasts. The only time the image burn in problem went away was on CCFL or LED backlit LCD sets.
The last line on this video was amazing. I'm hooked, but my head hurts...When watching this channel you should take a break in between just to let your brain rest. Love it bro!
I already understand how video works, but I must say that this is probably one of THE BEST videos I've seen, explaining how TV works! Beautifully illustrated, well narrated, etc! It should help any layperson pick up the concepts! I also didn't know about that "primitive" method of sending a fax! :) Pure genius! I "found" this video in the links that YT puts down the right hand side. I have watched Veritasium vids before, and I thought it should be interesting! :) Yes. Yes, it was. :) Well Done!
@@FollowerOfChristJesus-h7v nah, religion is pointless and fiction. Better off without it. Just have a moral basis for humanity instead, not creation myths and false hopes.
I thought for sure you would have mentioned the fact that Bing Crosby was basically the funding source behind the first videotape 2” systems from Ampex in the 50s. My first encounter with videotape was with the 2” system which quickly became a 1” open reel system. We used to edit videotape with a razor blade, crossing our fingers everytime an edit ran across the head. Then, over the following decades we had Beta then VHS, and off to the races it went.
At 4:18, the animation is incorrect! The 'vertical' coil actually controls the horizontal direction of the beam movement because the Lorentz force is perpendicular to the magnetic field! Edit: The animation at 8:20 has the same issue
I've read into the history of television many times and watched many videos and this was the best explanation of how television works I've ever seen -subscribed , liked , and VERY appreciated 😊😊
I guess I shouldn't be surprised that there are actually people who might not know this. I mean, to me, it's obvious because there is also 1080i, which stands for interlaced, so process of elimination and all that.
480i = Standard Definition TV 480p = Extended Definition TV (DVD) 720p = High Definition TV 1080i = [not sure] HDTV 1080p = Full HDTV 1440p = Quad HDTV (4 x 720p) 2160p = 4K TV (4 x 1080p) 4320p = 8K TV (4 x 2160p)
It's truly amazing how we get to this right now with this readily accessible technological advances. These great people who thought of this from scratch are the true unsung heroes
I've had that same gimbal for about a month now, pretty happy with it, and it handles compensating for the weight change of the lens telephotoing in really well. Crazy to think I was handheld shooting on Hi-8 tapes only a handful of years ago... Soon we'll all be shooting in 3D as a standard, and explaining to kids how those "old flat movies" were the standard. xD Great vid, thanks!
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.
Amazing how times have changed, and how quickly. Makes me wonder what's in store for my kids. They'll float around (sitting will be so passé) watching a hologram of their kid's baseball game (baseball is the only sport to endure), and they'll say, "Remember when we had to record two-dimensional video with our cellphones?"
Actually, every bullet that's shot is curved. It falls to the earth the same speed it would if you dropped the gun from your hand. Also, non symmetric bullets have a curved path, plus of course the curve due to coriolis. Still like the joke though :D
I think I missed the most important part to me: capture. I understood how the image was drawn line by line into a screen. But how did they manage to capture from the real life objects into first in black and white and then in colors? What technology was used for that? I think that was explained in a few seconds while the drawing of the image was explained in detail, and there is a whole story behind how images were captured electronically. Awesome videos by the way.
YipYapYoup yeah, it dances around the edges. If you look carefully when I insert the VHS tape into the VCR it says pt.1? So if there is a part 2 this will be a more central focus. The fundamental problem is data. But part of it is as addressed here, converting images into electrical signals is much more complicated than optically recording images on film.
@@sumaiyashahid2266 VCR is a video cassette recorder, people used to (and some probably still do) use them to record television broadcasts onto a video cassette, which contains a spool of magnetic tape, for later playback. Initially they were expensive (like any new technology) but became very prevalent in homes during the 1980s and '90s.

Yes, even if we as individuals each have general intelligence our discoveries and actions build up like sediment and create a super intelligence not one lifetime could achieve

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...
Wow, great insight!
what is the difference between film and video?
Film means the old physical way of storing/making videos while video in this case means digital way of creating/making videos. So an analog camera uses film but your phone is a digital camera.

Great to see how it was done after just being on the receiving end most of my life. Also I got involved in acquiring and editing video in the mid nineties. Oh, I also enjoyed your show on the wave pool, that is so amazing! Thanks for everything!
I remember those old AVR1 2” video recorders when I started in television. The heads were suspended on air bearings because mechanical bearings created bearings created too much time base errors. Also the capstan driving the tape had negative pressure to suck the tape onto the cylinder... then came the exciting time of rewinding the tape. Because the capstan was committed to driving the tape it would spin at many thousands of RPM, a break in the tape during rewind could be lethal so operators had to leave the room.
You could hear the machine rewind many buildings away.
They cost in the order of $250K back in the day.

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.)

Color CRTs do have pixels in a certain sense. They have RGB phosphorus dots lined up in a grid of triads. But instead of a circuit that activates them it is a cathode ray.

AHHH, OLD TV QUALITY! *IT BURNS!*
quite literally, old TV's often had burnt phosphorous and computer monitors gained screensavers for the sole purpose of preventing burnt in images :)
Image burn in still happens in modern sets, in fact it is a even greater problem on 4K OLED sets than it ever was on CRT sets. A friend of mine who is a TV technician went to a conference put on by one of the major manufacturers, Samsung or LG, I think, and was told to tell customers to limit viewing of content with static imagery including sports telecasts. The only time the image burn in problem went away was on CCFL or LED backlit LCD sets.

Which gimbal is it? I'm very unsatisfied with my Glidecam--too difficult to make fine adjustments.
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.
Amazing how times have changed, and how quickly. Makes me wonder what's in store for my kids.

I think I missed the most important part to me: capture. I understood how the image was drawn line by line into a screen. But how did they manage to capture from the real life objects into first in black and white and then in colors? What technology was used for that?

Awesome videos by the way.
"I always wanted to know why film looked better than video."
That's the first line of your description but the video doesn't explain that...
YipYapYoup yeah, it dances around the edges. If you look carefully when I insert the VHS tape into the VCR it says pt.1? So if there is a part 2 this will be a more central focus.
