How a TV Works in Slow Motion - The Slow Mo Guys 
Развлечения
I am electronical engineer of crt TV's for 20 years,and this is my first time in my life who i saw how it works an old crt television! Thank you very very much Gav!
Well i was at peace , but now im thinking about when we will get to see the camera that could film it ....
I don't think people realise the level of technology that went in to crt's, compressing 6 signals into one waveform was an achievement in itself (colour tv).
Was nice to see what we knew in real time though..
Redpower understands the level of technology that went into crt's lol
I read up on the development of both NTSC and PAL in the 90s. They were a huge achievement. NTSC allowed older black-and-white TVs to still view the new color broadcasts since B&W TVs would ignore the chrominance line and only read the luminance line while only losing .03 fps in framerate on both color and B&W TVs. PAL, used primarily in Europe, Africa and most of Asia, had slightly higher resolution and was configured in such a way that signal degradation caused loss in saturation (intensity of color) rather than the hue (shade of color). This led to a better-looking picture in many places.
I'm surprised you never seen the effect on a CRT before. Growing up working on CRT TVs, my dad taught me how to manipulate the control circuits enough to slow the scan-out down to strips roughly an inch long. We did so by simplifying the circuit so that it would strobe the cathode ray repeatedly over the same segment but at such a slow intensity that persistence of vision doesn't work thus allowing you to see the scan out. It was thanks to those early experiments in my life that I developed a very deep and almost intuitive understanding of how displays create color, motion and the various other higher level illusions. All I really needed to supplement that knowledge was a relatively light study of how the human eye perceives color, intensity and motion. I doubt I would have taken to pixel/fragment shader development as well as I did without that knowledge, a lot of the ways I pulled off fancy effects in the mid-2000s relied on these illusions.
ok
Slow Mo Guys is one of the few RUclips channels that deserve every subscriber they have and then some
Click baiters, click bait them
It's one big ad for LG
Bru this not clickbait
@@tdawg6752 wooosh
My father was a TV repairman and electoral engineer. When I was thirteen, he explained to me how a CRT tube worked. I understood it but could not picture it in my head. Thanks to this channel, I saw it for the first time. BTW. I am Sixty-One years old now. Our brains run so s l o w...
even today, computer's operationg system's kernel is very very hard to be implemented. Real scientists are real heros of us, thanks to them :)
@@crypticaledits someone that does in all caps. Are u really doubting a comment like that lol
a short and sweet story and little gratitude you gave for helping picturise what your father said a long time ago. Sounds heart warming. 😊
Did he have the ultimate set of tools?
(That's a reference to one of the greatest movies ever made, in case you aren't aware.)
@@crypticaledits It's just a dead normal abbreviation for: "By The Way". People used to use abbreviations like mad during the 1980s, 1990s, and 2000s. Kids aren't doing anything new or unique by using official abbreviations.
I feel like CRTs were magic for the time, I seriously wonder how they managed to get this level of accuracy and speed with the technology available at the time, it blows my mind
I totally agree, honestly its really funny that humanity invented 'gun that shoots electrons that are then aimed by magnets at a screen' before 'several tiny lightbulbs that dim and brighten' like one of these seems infinitely more complicated than the other one, how did the electron gun come first??
@@commandrogyne LCDs are liquid crystals that rotate polarised light, controlled electronically with backlit regions. This is much more complex than a CRT. Only now with OLED, are we using the 'several tiny lightbulbs approach. The production of something with so many parts is much harder than shooting electrons at glass.
Wdym with the technology available at the time? Do you think they were some kind of primitives using rocks and sticks to build TVs? Do you think the tech we have today just spawned in? Lmfao
@@AverageAlien i dont think ive ever read anything as stupid as your comment
@@commandrogyne i know right. CRT seems vastly more complicated than LED
Quarantine got me learning how a TV works
Yeah
True
same here
don't you mean tyranny, anti-freedom, slavery.
Same here
This is the best video you've ever done. Taking an every day object and letting us appreciate the technology more.
I was just about to say that. Probably my favorite video by them.
YES. This video was unbelievably fascinating.
And extremely informative and educational as well. I'd love to see more everyday objects examined with super slow-mo to explain how they function.
The dialogue felt a bit stunted, but it was really really interesting
Too bad they didn't do a plasma display as well.
The most incredible thing here is how cameras are capable to capture and slow down images.
When you think about it its actually not much more complicated than a regular camera, you just need to capture video at 100s or 1000s of frames per second rather than 60 or 30, then just play it back at 60 or 30 fps. You could do the same with a regular camera, but you'd lose a lot of detail in between each frame and it gets quite choppy below 20fps.
they don’t slow down images
What I'm picking up is they need to do a slo mo of a slo mo camera.
The CRT was so fast that even at that framerate, the trail of light was dashing across the viewfinder. Insane
I think many people probably already knew most of what you explained in this video (scanlines, RBG pixels, etc.); but to actually SEE it demonstrated so precisely with super-high-speed and macro-lenses was truly fantastic. So much different than a normal #SlowMoGuys episode, but this one might honestly be my favorite. GREAT work, Gavin!
Thanks, my dude!
Hello Jogwheel! I like your movie reviews..
+The Slow Mo Guys Hello Slow Mo Guys
Holy crap its the "is it OK to microwave this" youtube channel. Jogwheel I love you guys. Jonathon thank you for keeping the channel going.
Yeah this and the cd one are my favorites by far
Wish companies would do more stuff like this to advertise products instead of annoying ads or bs marketing.
This has the perfect amount of likes
Richie thas a lot of effort
@@martywalters4804 i myself Will enjoy this kind of ads actually. Like, even sometimes i search for some good ads on youtube
Good idea
Cable is the enemy and Adblock is your friend.
I now understand TV displays better than ever before. Thank you for this incredible video!
came for the slo mo...left a display snob.
Dude, you know when your phone screen cracks or when you spill water on it and you can see the RGB colors?? It all makes sense now!!
I just need to point out 380,000 frames per second is absolute MADNESS.
Well done; very well explained.
that is nothing compared to 10,000,000,000,000 fps per second,in one of his videos
That's the best advertisement for an OLED tv I have ever seen. Awesome.
It really was, I’m sold

Wow OLEDs look amazing. Good last minute marketing decision by LG there!
they just won a customer here
man you people are easy to influence :)
Modern OLEDs also have a white subpixel (RGBW), typically on the newer LG screens. This improves the maximum brightness.
Wild Mitchell I prefer Samsung AMOLED 😁
It's really great. Can't wait for Samsung to get into the large panel OLED TV market, as I am a Samsung fanboy lol
I cannot explain how much I love this video. I spent many years teaching all manner of things related to video. I was over of the most week known trainers in the audio visual industry and this video blew me away. Too see the things I was teaching about captured on camera is awesome!!!
I'm coming back to this video every now and then, so I want to thank you for it. Super fascinating and brilliantly presented!

I love how slow-mo Gavin is so well spoken and intelligent, and then Let's play Gavin is a screamin oaf.
Amazing.
Alice Kingsleigh I know. It makes me feel weird hearing him be smart, and like not accidently sounding smart, or trying to sound smart and failing at it.
Rooster teeth on screen Gavin is totally just a made up character he does for the camera.. Several people who are close to him will tell you he's one of the smartest people on the planet lol
Also, even more amazingly, each LED is turning on and off continuously, which is how LED brightness is controlled.
Wow! That sounds like part of a new video. Gav?
omg, looking back at this, he is SO charismatic and chill.
I remember putting my eyes right up against those huge crt screens as a kid & seeing the rgb bars!
they're called subpixels btw
Brendan Koskey rain on him why don’t you I guess
Your chin is sharper than my pencil LOL
Sorry had to do this
@@bigchungus9061 I believe that would be the mustache thats sharp.

Fantastic. You explained everything so clearly and concisely. Thoroughly enjoyed this. That LG TV was incredible.
You should buy one of those LG OLEDs. I lusted after one for a couple years, and snagged it on a big sale. They're even cheaper now. Get ready for fun conversations like watching a movie with your girlfriend on an Imax screen (the lameo Imax they have in major theater chains), and having her (not a techie) lean over to say "this would look better at home."
That is nerd win times a million.
aluisious LMAO
I couldn't believe the clarity!!
It's a Sony tv
Deeney Im a small youtuber and I don't care about the money but getting videos monetized is like this feeling where you can finally make money off of what you love even if it's a dollar it just motivates and inspires me that what if one day I can make a living out of what I'm passionate about and I get to sing and write songs all my life instead of being a doctor or an engineer just like my parents are pressuring me to.
I hit 10,000 views 3 months ago and youtube said my channel was still under review and they'll tell me in a week and it stayed that way for 3 months and now youtube says i need 4,000 hours
FOUR THOUSAND HOURS
i make 4-5 min videos
How many videos should that be. This is so frustrating when i found out i felt like crying because it puts into perspective how small i am and how not good enough I may be and it's so sad. It slightly demotivates me and makes me think twice about my life-long held dreams.
I don't know why youtube is becoming this sad place
Oh by the way it's my birthday and I'm upset lol
You’re worth all these likes and views. I know about these technologies by theory, but seeing it in action got my tears. So amazing.
This is amazing. I had no clue how fast a TV display had to be. I also didn’t know what OLED TVs did. Very fascinating.
I was just shocked only just looking how big is your TV in comparison to mine
ANTU SULAKHE i have a 70 inch, idk if he has the same or bigger lol
Yeah, it's a bit bigger than my 32" widescreen Sony FD Trinitron :D
Same
who needs TVs, I just got my Desktop PC, Laptop, Phone, Switch and 3DS xD
Am thinking of getting a couch tho...
Broockle u can't fuck girls on a tv 😂
Finally something on trending that is actually interesting.
Black Market ikr 😂
My first job was in a CRT TV factory.
This is a review to me, and what a really good video it is.
This one was SO interesting to watch! I've just found your channel in the past month and I'm binging all your videos. LOVE IT!
I learned more in this 11 minute video then I learned in a months worth of High School...
Lucky, I never had a class on TV technology in high school.
I'm in college for television and I feel like I learned more from this video
Unbox Easy looks like a 12 found his way into photoshop if I had to be honest

This video should be top trending
Cmon youtube

It's at #40 as I'm replying.
Your prayer has been answered
It's getting there. #13 for now
AAGHOSTT ikr
5:06 A couple of weeks ago I was watching a Nintendo NES hardware video, and I was amazed how something so old can do specific calculations, switch banks, etc, depending on the specific scan line that's being drawn. It was something like, on scan line 23 switch to this bank to get this sprite, then on line 27, switch back, 35, etc. It's a full world when you slow things down and realize all the activity that's going on.
Now THIS is what I like to see as the number 1 trending video
Look
At NUMBER 1 right now
gamer guy yup now it's another bullshit click bait video
This has got to be one of the best videos you have made. It was both entertaining and informative. Granted you had me with the soccer ball (OK I'm an American) to the face, and a sword going through water bottles is entertaining and does have educational merit. However, something like this video touches on real life experiences and reveals things our unaided eyes could never grasp. Thanks for the great job. Slowing down the little things we encounter in real life so they can be properly observed and better understood is a gift you give us all. Thanks.
Tony Colle wow that was a great summary
i have to agree. i have ALWAYS wanted to see the horizontal scan of a CRT ray. i had seen the vertical lines being built before but never this. awesome.
Agreed.
You guys truly redefine RUclips videos this WAS AMAZING!!!!!!
i love how at 1:14 gavin said the word eye, and the two most beautiful eyes appear from the back of the tv. purr-fectly timed.
Well, this video is going to be used in physics classes for years to come.
Wheatley - exactly what I thought! Well done slow Mo guys!
This ended up being more interesting than I thought it'd be
Great video. I was surprised to see how quickly the image fades away. It only takes the time of about 2 scan lines for the image to be gone already.
This is gold. Pure gold. One of the mysteries from my childhood is finally resolved.

Nice Video ... Even this can be part of curriculum for Computer Graphics ... you have literally demonstrated refresh rates , how it goes left to right , the atomic pixel and RGB concept . Wow , I learned a lot . Keep it up , my bad watching in 2022 while it was uploaded in 2018 .
the best BASIC explanation how a TV works....its soooo amazing to think that how a basic day to day thing in our homes like TV works with so complexity and we dont even consider it...by far my most favourite video of 2023
My lecturers at college - 40 years ago - would have had loved this technology. Them trying to explain how an interlaced, 50Hz image is produced on a CRT was a nightmare to understand. LOL
geoffphuket same here.. It blew my head off when trying to understand the different screens and the evolution from CRT to LED. Would have been lot more easier with this video to understand.
This might have been one of your most interesting and useful videos to date. I learned a lot of useful information about TV's.

Love this video so much. It''s the first time to see the tv pixel displayed this visionly.

Remember in the old days when TVs smelled like electrons and were static-y when you touched the screen? Those were the days...
You actually made me nostalgic for screen static, why
Omg same
Lmao I’m 18 and that was like my childhood. And then when you had the tv on you could hear that really high pitched hum. I heard it in this video and it still hurts my ears lol
I used to hear that sound constantly when my school had crts but thankfully we have laptops now to watch am news

By far one of my most favorite videos due to the educational content in an entertaining format. The only other video I love is the fire tornado just cuz it looks like CGI in how mesmerizing it is :D
I'm so glad to find this Channel again after many years and watch this super fascinating video!!!
Now that's just crazy!
I think I learn more from this channel than I do from school!
the GOOPER Wow, thats kinda sad
actually pretty accurate, another example of this is the crashcourse channel. Certain nationalities for one are pretty much censored in classes like primary school education, it's not until secondary education that you get to study them, at a cost, so many dont.
It’s not sad. School teaches you how to become a drone. Watching something like this voluntarily is considered self-education.
So true
It's ya girl T would agree with you. Education from school is the basics. It's up to the individual to continue and grow. Calling people sheepole or drones is just showing that they don't understand what's going on. Science is truth.
Omg I hear that high frequency sound when you turn on a CRT TV. Almost forgot that sound.
Proof that my ears are destroyed - I didn't hear anything of that high pitched noise... ^_^
How i knew if my parents had gone to sleep, ring or no ring lmao
LittCoin Af Yep. You could hear that TV buzzing from hundreds of feet away.
Well, I guess we know they have a good mic....
I know it very well. It sounds like my Tinnitus
This is one of the best videos of RUclips big thanks to your effort.
Wow…… thats so cool. Really makes you appreciate the minds that developed TV’s.
I really enjoyed the home-y feel this vid had.
IronOpinion I'm trying to embed this kinda of revenue-generating-homemade-candid-professional style to my company. They're relaxed and it's fun, but they know their shit and it's probably more informative than a boring academic video about the same thing.

This might be the best video on youtube for me. Thanks for making this.
The one thing that amazes me the most about CRTs. Is that there is a Bi-Polar Junction Transistor switching thousands of Volts which moves that beam around to scan the image tens of thousands of times per second.
It also amazes me we commonly used an electronic device which can bend light with electromagnets with extreme precision and none really cares.
RogueRAZR Totally agree! It’s not really old and crap, it’s actually quite amazing how they can do it.
Those suckers were full of lead to protect from x-ray emissions, too.
+RogueRAZR Well, technically it is an electron beam that is being bent, rather than light, but yes, people back then had just as much ingenuity as people today. We've just learned how to do more things over time--we're not any more clever than before.
I have done this in a lab honestly its basic electromagnetism all youre doing is bending an em wave
rbrtck True. The electrons react with phosphor to create the actual light you see.

It would be interesting to see the arrangement of red, green and blue subpixels on different screens because even different OLEDs use different arrangements.
Yes! I wanted to see the fully lit arrangement on that OLED LG TV. Even when only partially lit, you could see that they are not all the same shape and size like in the LCD. I don't know if this is a PenTile arrangement or not, it would be interesting to watch.

Thank you so much for the epilepsy warning. I didn’t watch the video :(, but that warning saved me a lot of suffering. Most people don’t think to add such things. You are very considerate. :)
Genuine question, would you not have guessed that a video about tv in slo mo would be a risk?
It didn't flash much i'm sure you'd be fine
JellyMan3634 I don't mean to be rude, but that is an ignorant comment. I don't know much about epilepsy, but I'm sure even a small bit of flashing could set someone off. I would encourage you to think before making comments about medical conditions you know nothing or very little about.
I have photosensitive Epilepsy and I watched the whole video and I am fine, just take your medications and stop being over dramatic
What is epilepsy? What would have happened to you if they didn't give any warning?
May have been the most fascinating video of yours that I have seen.
Thanks for the cool crt scanning, which I've not seen before. Cheers from New Zealand.
This is video I have been waiting to see ever since I was three years old and stood so close to the CRT TV that my hair reached out and touched it. I finally understand how it all works.
I used to put my face up to the screen when I was little and remember seeing red in the whiteness and always wondered why.
