How many bits per pixel is YUV420?

This is very advantageous for compression because YUV420 requires 6 bytes per 4 pixels, or 1.5 bytes per pixel, because groups of pixels share a single color value.

How many bits per pixel should I use?

As of 2018, 24-bit color depth is used by virtually every computer and phone display and the vast majority of image storage formats. Almost all cases of 32 bits per pixel assigns 24 bits to the color, and the remaining 8 are the alpha channel or unused.

What is YUV420 format?

In particular, YUV420 means that the U and V channels have half the resolution of the luma (Y) channel, in the horizontal and vertical directions. The sampling method usually present in low to medium quality JPEG images is YCrCb420 (high quality JPEGs are usually YCrCb444 (no subsampling).

Which is better RGB 32 or YUV?

YUV color-spaces are a more efficient coding and reduce the bandwidth more than RGB capture can. Most video cards, therefore, render directly using YUV or luminance/chrominance images. The most important component for YUV capture is always the luminance, or Y component.
