Some professional recording equipment records in YCbCr 4:2:2 Human eyes are much more sensitive to light, but less sensitive to variations in color, so in most situations you wouldn't notice that averaging.īluray movies, Youtube content etc is compressed using YCbCr 4:2:0 so instead of 4 Cb, only 1-2 Cb values are sent, or only 1-2 Cr values. 3 x 8 bits or 3 x 10 bits or 3 x 12 bitsĤ:2:2 and 4:2:0 means that the video cards makes groups of 4 pixels, sends the brightness information for each pixel untouched, but makes an average of the color information for those 4 pixels and sends only 1 or 2 values for the whole group.
a formula is used to determine red, green and blue from these 3.Ĥ:4:4 means that for every pixel, the monitor receives red,green and blue, or ycbcr information.
YCbCr is same thing as RGB, but instead of colors you have Y = Brightness (Luminance), Chroma Blue and Chroma Red (color information). RGB is 8 bit per color, 16 million colors
