YUV 422 Video Format

The 4:2:2 format is a type of chroma subsampling used in digitizing video signals, reducing colour information while maintaining luminance. In this format, for every four pixels, there are four pieces of luminance information and only two pieces of colour information for each pair of pixels. This allows for smaller file sizes without significant loss in image quality. The 4:2:2 subsampling method is visually represented by a full line of luminance values and half lines of Cb and Cr values. It's widely used in broadcast television, professional video recording, and various other applications as an efficient way to compress video data.
