it's almost ridiculous how good you are at explaining things. Well done indeed. You should seriously consider a job doing that, if it's not your job already.
Had the same exact thought. I don't think I'd have application for most of the other videos on your channel, but I feel like I want to watch every single one of them just cause I'm sure I'd understand anything explained like this
You have a talent at explaining things. Never seen anybody expressing thoughts so well structured and consistent. I understood everything without referencing to external resources. Thank you very much from Russia.
This really is the best video on this subject on UA-cam. Well done! I understand the difference between these two formats way better now. Props for using real world examples to explain concepts too. That's a sign of a great teacher right there!
Thank you mate. You have a great skill in explaining things. Your voice was so relaxing and your explanation were so confident and bold that I could literally feel the RGB vs YUV differences though I was stuck understanding the core differences while searching.
You are perfectly right. I have a Skyworth TV panel connected to a Geforce gtx1070 ti, and used to set RGB full range. Always with a default wrong tonality tending to blue. To have a more warm white I've tried to combine a slitghtly higher red and green, but the result was a loss of saturation. When I've switched to YCbCr the colors went back to the right saturation keeping the mix previously choosen, and it definitely looks like all the colors have the same saturation. The fact itself is weird to me because at the end the conversion should be rgb, but somehow it worked, somehow the colors processing is better.
fabulously explained. I searched for a video explaining this, because googling only threw two kinds of results: either too trivial, with gamers forums talking about "which is better: rgb or yuv", without really penetrating the subject, or with too abstract literature such as Wikipedia's entry on yuv, very cryptic. Your explanation is remarkably better to all previous findings. Cheers and you just earned a new suscriber. Regards from Colombia, South America.
Your delivery/explanations reminded me of a couple of favourite teachers from my old high school days (looooong ago, heh) and I mean that in a good way. Beautifully done, and subbed!
Fantastic video! I would suspect that it's not that our eyes are being bad at seeing color. It's our eyes/brain being great at compensating for shifts in color, reconstructing the image for our perception.
As I was watching this I was hoping you'd touch on the old B&W and colour TV problem. Well done! I remember at the age of 5-ish when my parents bought our first colour TV, I asked them to make sure I could still watch all the same shows, specifically Sesame Street! It seems even at that age I could at some level understand the potential problems with changing a broadcast system and maintaining compatibility!
Well I’ll be damned. Someone finally explained it in depth. Most videos just explain it in a way that is straight from the dictionary. Even a dictionary way to help “show” it. Anyways thanks!
I was just checking out the NUMA video and realized that out of all the channels which cover Computer Science Topics. You have the best methodology of teaching. The audio quality is really good and the visualizations are enough and not daunting for newbies. I think you can do something big out of this. Maybe start with an Operating System playlist or Algorithms. Seriously dude, If you bring the simplicity out of complex topics in advanced subjects like AI and ML I'd stop watching 3Blue1Brown haha.
YCbCr 4.4.4 format output seems also have anti-aliasing effect. When I'm change this setting on Nvidia control panel all round icon in desktop and round object in CSGO is anti-aliased, this effect is maybe just the combination of my monitor and GPU but if this work you just got free performance anti-aliasing.
At 5:27 he said that the Cb and Cr values ranges from a negative to a positive number. But other websites are saying that YUV pixel values range from 16 to 235. The 16-235 range doesn't actually make sense to me. Can someone please enlighten me with this matter?
16-235 is a range used for RGB, sometimes referred to as RGB limited. The absolute range for a U or V component in YUV isn't that important and differs by system. Like I said, in a computer using 8 bits it may be - 127 to 128, but you may as well use 0-255 (that gets you into the whole 2s complement thing) while in the analog world the values can be expressed as a percentage, or using 1 for 100%. the point is, the exact range of the numbers doesn't matter: the principle remains the same. For that matter RGB doesn't have to range 0-255 either; 0-63 or 0-4095 are perfectly possible too.
RGB is a three-dementional colour space. Colour systems would be sRGB, Abode RGB and so on, they are a part of the same space, but differ in coordinates.
Yes indeed. I wasn't denying that right? Edit: Oh well just noticed I did call RGB a "system" a bunch of times, the thing is, these terms are loosely defined and a lot people use different terms to describe these things. In fact, "color system" is usually used to describe systems like RAL and Pantone. Things like sRGB and Adobe RGB are often simply referred to as "color space" or, if you want to be fancy "color subspace".
Well, there is “people” approach and strictly technical one. If we are trying to be mathematicaly correct then we have a bunch of vector spaces with different axis. RGB space is a “cube” of sorts, CMYK is a four-dimensional “tesseract”. Inside that space we define coordinates to describe a colour. Those coordinates are strictly mathematical and are defined by CIA RGB 1931 if I'm not mistaken. We then use those mathematical definitions to agree upon the colour of roadsigns between countries, for example. And only upon that space different consortiums of tech companies, TV broadcasting firms and other entities try to come up with industrial standards like Rec. 709 or the new one for HLG/HDR. The same goes for sRGB, Adobe RGB and others, they are temporary and in constant change. While CIA RGB is constant, it doesn't change for almost a century and many people confuse RGB space with sRGB system (and it's outdated and being dropped in favour of Adobe RGB). There also is a bunch of formulas to convert image from one system to another we have to use for different devices and means of image transfer. So to comprehend all that complexity I would have used terms that are used by International Union for Electrocommunication (I don't know how it's called in English, in Russian that's Международный Союз Электросвязи). But surely you haven't made any mistakes, that's just my suggestion, your content is great as always!
Very well made video but that didn't answer my question so if you had a monitor with HD capability and options to get RGB or YUV, which one would you choose and why?
@@AKIOTV WOW, that was a fast response (for the record, you responded back in less than 10 minutes while we seems to live in two different continent!). Well, all my eyes can differentiate between there two modes are the screen sharpness which RGB tent to have a higher visual brightness but I am not sure if it happens as a result of what my graphic card driver translates to visual effects vs what it should be in reality.
@@Revolutionized In practice there could be slight differences between specific implementations of either yuv or rgb, but in theory the information is the same, considering full range rgb and yuv 444.
In gaming like's consolle things ....which is better ? Or there is a " lag input colors " ? RGB is much faster than YuV42 ? I do prefer YUV colour format on ps4 pro with nanocell lg tv !
So what’s the difference in 4:4:4 and 4:2:2 and 4:2:0? I get thats it’s a “part” but how could you have less parts? How could less still give an image? Isn’t all of this converted to RGB by the TV or by the device (say a blu ray player)? I’ve wondered becuse of tinkering or looking through settings I can choose RGB, then forks of 4:4:4 and then bit depths that may even exceed any tv I can think of (16 bit)
I can't remember exactly how (or if) I explained this in the video, but basically with 422 the U and V parts of each pixel are compressed, reducing color resolution. (ie how close the pixel is to the originally recorded color) However, unlike with RGB this does not affect image sharpness as the luminance (Y) data is untouched.
What is proper to use on a Nvidia Shield for HDTV and for movies streaming. It has RGB and YUV modes. YUV looks darker and more contrast. I have a LG monitor that is 1080p non hdr.
Question; Are any of the two color models more effective at handling HDR than the other? Wondering because Forza horizon 4 looks better, for me atleast with YCbCr. RGB makes colors look flat and dull. very good video btw! thumbs up!
hello plz can you help me i'm using 2 monitors and the main one is using vga to hdmi cable and the 2nd is coneccted to the other port i've recognized that movies and games became so much dark i search this again and again until i found what is called the (RGB) in nvidia control panel i change it to YCbCr444 and colors are back to normal but when i install a new game the first monitor in going to sleep id why plz can you help

Dude this guy's voice is so relaxing to listen to while at the same time it's by far the best video explaining the topic, it's crazy!
This guy deserves to be hired @Harvard as a lecturer. Great Explanations. Concise and accurate
You have a talent at explaining things. Never seen anybody expressing thoughts so well structured and consistent. I understood everything without referencing to external resources. Thank you very much from Russia.
My man, tomorrow is my Multimedia exam and trust me you explained it to the depth in the shortest period of time.
best voice ive heard next to morgan freeman
Agreed, totally!!
thank you for a very good and straightforward explanation of the RGB and YUV systems, much appreciated!
This calmness in conveying detailed information is simply fantastic, thank you so much
I watched this video three times just to hear the sound of a good explanation again, again and again.

I'm not even sure how or why I stumbled upon this video, but this is a very good explanation of the YUV system
You definitely deserve more subscribers
Not all broadcast engineers can explain this. But you did it like a pro.
You have been able to explain to me in a very simple yet complete way what I always wanted to know. Thank you . Wish you every success
Thank you mate. You have a great skill in explaining things. Your voice was so relaxing and your explanation were so confident and bold that I could literally feel the RGB vs YUV differences though I was stuck understanding the core differences while searching.
On of best explanations about this discussion in UA-cam (i ever seen!)
This is a great explanation. I didn't realize the importance of black and white transmission, backward compatibility.
Thank you for the wonderful explanation, you have a very wonderful style, I wish you all the best
Thanks!
The best explanation seen so far, thanks ..
This is the best video on the topic. Your content as well as delivery made it so easy to understand. Thank you for making this! Really awesome!!
Nice work. Please keep making vids like this, they are great.
Needed a quick and good explanation on YUV, and this was excellent. Cheers.
Clean and clear. Thanks a lot for the work.
I have understood it better now than after 3 years of college. Such a great teacher!
This is the _perfect_ entry video on the topic and deserves way more than 8k views.
8k is quite a lot to me though
Your voice is too soothing, Great explanation !!
Nice explanation indeed. The historical perspective behind using YUV was very interesting to know.
You just saved my day! Thanks mate! :-D
The best explanation that I have seen so far. Keep it up, mate.
