8. Command-line Syntax
8. Color Spaces / Chroma Subsampling
------------------------------------
Avs2YUV converts the output of your Avisynth script to the YV12 format,
i.e. YUV data with 4:2:0 chroma subsampling and 8-Bit precision.
Usually this is exactly what you want/need. If, however, your Avisynth
script outputs image data with a higher chroma resolution, e.g. YUY2
(4:2:2), then the conversion to YV12 (4:2:0) will discard some of the
information. In that case, if you want/need to keep the full chroma
resolution of your Avisynth script's output, you will have to pass the
"-csp" switch to Avs2YUV as a custom parameter! Use "-csp I422" for
YUV 4:2:2 (YV16) and use "-csp I444" for YUV 4:4:4 (YV24). Note,
however, that Avisynth 2.5 did NOT support YV16/YV24, so you need to
use Avisynth 2.6 or Avs2YUV will fail! Also be aware that x264 itself
will convert any YV16 or YV24 input back to YV12, if you don't pass the
suitable "--csp-output i422/i444" switch as a custom parameter to x264!
