YCbCr and RGB Colour

Should vector base image may work better and less space

32bit rgb vs yuv for movies, who is better bro? Im confused 😢

Stright forward, short, to the point👍Love it

One of the best video ever seen, perfectly explained

In YUV you can concantrate the information more on luminance than on chrominance. A human eye is more sensitive to brightness, therefore it is more convenient to have more brightness levels then color tones.
In 24 bit RGB (32bit without the 8bit "alpha channel") you can only generate 256 shades of grey. When you color a square with a gradient from black to white from left to right, you can easily tell the difference between a lighter and a darker shade.
Now draw a gradient from red to yellow, you still have 256 vertical stripes, but it's very hard to distinguish two adjacent shades. The same applies to blue-magenta, green-yellow, etc.

Which one is better? Or have more information?

ok but it's cap that "people can't see 16 miillion colors" they can actually see more then that. for example mac p3 color displays proves this as well as adobe rgb displays. compare that to a normal display and you will think the colors of srgb are dull.

Why choose color gamut from 0 to 255 in image processing

Adding to the pile here but the way that you lay out information is fantastic, thank you for putting this out.

Thank you for video.. finally my search got fullstop. by this channel it has cleared all my doubts

can you help me?, how can i set ycbcr setting in MI 4K BOX

24bit RGB contains every single possibility of colour and there are no repeated or missing values. Can 24 bit YCbCr claim the same? Are there any duplicates or missing colours in 24 bit YCbCr, or is there an analogue for every single combination of those 24 bits in YCbCr when compared to RGB?

OMG, your English... it's awesome! thanks for explaining such a complicated concept in a such easy way! thanks!

Great video, Thanks!

Stilins TVs come with ycbcr/ypbpr!

This is very nice 😊

Where does the YCbCr color cube come from? For example, the RGB color cube came from the fact that each axis was a particular color component, with 0,0,0 being black and 255,255,255 being white. It makes sense visually - the corner where (255, 0, 0) lives is red. The corner where (0, 255, 0) lives is green. Etc.

The YCbCr cube, however, kinda is just magically given, with a very specific visual color at each location, but without any intuition as to why a particular point on the YCbCr cube is a particular color.

For example, in the first face of the YCbCr cube that you show (the side with pure white in the center), you can find a very light shade of lime green in the bottom left of that face. However, there's really not much intuition that, in order to get that shade of green, you need "highest value of Y and most negative values of Cb and Cr".

Perhaps the confusion stems from the lack of intuition over what exactly Cr and Cb *mean*, or *are*. In RGB, R, G, and B can be summed up as "the amount of Red, Blue, and Green each in a pixel". Is there a similar intuition for YCbCr, like "the amount of red and blue in an image at a particular brightness"? If so, why is green where Cb and Cr are both at their minimum values?

This is bloody brilliant

YCbCr444
YCbCr422
YCbCr420
RGB

Which is the best?

Excellent video while I was looking to just answer the Ycbcr/Ypbpr difference I had figured out more than I bet for.

I watched this on some other POS site through subtitles and still very well explained so I watched it all in CC before coming here to like it :D

Very well explained. Thank you!

I have a PC with AMD RX 570 GPU and I use with Samsung QN90A Mini LED TV connected with HDMI 2.1 which color space is better to use? By default AMD driver sets the YCbCr 4:4:4 they shown as "Pixel Format" option, also the RGB 4:4:4 PC Standard Full RGB, which one is better? I think I will let it on Full RGB since some tests I saw shown the darker scenes "better" I mean more visible, especially in games.

Immediate subscription, absolutely LOVE your explanation of this that I instinctively clapped once the video was over because so many professors tried to explain this to me and none did in such a colloquial yet detailed manner. Thank you!

An excellent description, thank you. This was your first video that I watched but you got a subscriber nevertheless.

Where is the rest of the video? I was just getting into it, and the video was over. Thanks for posting.

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

What do you recommend for PS5

Great Teacher 💯

People that think RGB is the right way are wrong RGB is used for PC monitors to get the full colour space out of the monitor but TVs are different if you choose RGB on a tv it’s incorrect it’ll make the image too dark blacks will be crushed TVs work differently then pc monitors. The correct input for a tv is 4:4:4 the tv will take that colour space and give you proper blacks and whites. RGB will crush the blacks

Thank you, this is so helpful

Oh my god finally I understand it

Excellent video!!!

Great explanation, thanks!

Thank you for this short, but helpful video. Right to the point.

in a single video, everything is cover about RGB and YCBRC color model

Gracias por tan completa y comprensible información amigo, saludos desde México!!!

Thank you ever so much, I understood perfectly and I have no further questions!

Not difference

This was fantastic and so well illustrated. Earned a sub. I would absolutely love more videos about color science from you. For example RGBA (how alpha channel fits in) or what the difference betweeen sRGB, Adobe RGB, Rec. 2020 and DCI-P3 is.

Full RGB or YCbCr 444 for computer HDMI output? Which is better?

ur voiiice damn very gooooooooooooooooooooooooood

So how does it save bandwidth? I get that you say it can be compressed but how? How does the math of it work?

Thank you this is the first video that clearly told me a difference. Most just say “it’s different becuse it’s different”. Interesting.

why does RGB give me ugly purple font? on my text

absolutely clear !
