 Y′UV colorspaces have an associated matrix that defines RGB coefficients and Y′CbCr encoding ranges. It is very important to specify the correct matrix, or the video will be improperly processed and come out with slightly different brightness and colors.

 YV12
 A planar Y′UV 4:2:0 format, with chroma (UV) sub‐sampled to half the size of luma (Y′). Both width and height must be mod‐2. This is the format usually used with H.264, MPEG‐4, and web video formats.

+It is very important to provide the correct [[ResampleHQ#Matrices|matrix]] when using Y′UV colorspaces, as the results will otherwise come out slightly wrong.
 Despite the actual requirements of these Y′UV colorspaces, Avisynth requires the final output of your script be of mod‐4 width. Because of this, most filters also require these colorspaces to be of mod‐4 width. The ability to use mod‐2 widths is kept as an expert option in ResampleHQ.

 ResampleHQ produces correct results using a high‐precision 100% linear pipeline. Because colorspace conversion and resizing are often essentially the same thing, we can perform both operations at once for higher performance and better quality.

 This image was cherry‐picked to show the detrimental effects gamma‐ignorant resizers have on images with high contrast. It also has an extremely high‐res source (4800×2400), which compounds the issue futher as more pixels are blended to get the final result.
