On a real source I don't think in_color_matrix=bt601 would be correct.
in_range=full:out_range=tv IIRC failed testing with color src (I guess
it already scaled) but would be correct (and default anyway) for real
source.
Correction. Testing indicates the specification of in_* confuses
ffmpeg even more. What seems to be "the way forward" is:
Don't test with color src - use something real and you may see different.
ffmpeg -y -r 30 \ -filter_complex ' color=c=00aa00:s=320x200,
scale=out_color_matrix=bt709:out_range=tv; color=c=00aa00:s=1280x720,
scale=out_color_matrix=bt709:out_range=tv' \ -c:v libx264 -colorspace
bt709 -pix_fmt yuv444p -profile:v high444 \ -qp 0 -preset:v ultrafast
-t 5 greenz.mkv
Works but color is special and of course it "breaks" the sd version.
