The number of distinctive shades a pixel can characterize relies on the colour depth expressed in the amount of bits per pixel. A standard way to lower the quantity of knowledge necessary in digital video is by chroma subsampling (e.g., four:4:four, four:2:two, and so forth.). Because the human eye is much less delicate to information in color than brightness, the luminance data for all pixels is managed, even though the chrominance information is averaged for a number of pixels in a very block, and precisely the same value is useful for all of them.
