29 direction are possible, common factors are 1 (no subsampling), 2 and 4, with
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

45 value of two consecutive pixels. It effectively models the chroma of a pixel
49 - .. _yuv-chroma-cosited:
54 odd number of taps. This is referred to as co-sited chroma.
