26 differences, is called chroma subsampling.
28 While many combinations of subsampling factors in the horizontal and vertical
29 direction are possible, common factors are 1 (no subsampling), 2 and 4, with
30 horizontal subsampling always larger than or equal to vertical subsampling.
33 - `4:4:4`: No subsampling
34 - `4:2:2`: Horizontal subsampling by 2, no vertical subsampling
35 - `4:2:0`: Horizontal subsampling by 2, vertical subsampling by 2
36 - `4:1:1`: Horizontal subsampling by 4, no vertical subsampling
37 - `4:1:0`: Horizontal subsampling by 4, vertical subsampling by 4
