Video Chroma Subsampling

Chroma subsampling is a method used to encode videos by implementing less resolution for color information than for black/white information. A common subsampling type used for videos is 4:2:0.

Why do we test it?

Chroma subsampling takes advantage of the human's visual system's lower acuity for color differences than for black/white. Savely removing information that we can't notice saves bytes, resulting in lower file sizes.
