Youtube re-encodes everything it gots. If case of video in yuvj
(full/jpeg/pc range) youtube re-encodes it into yuv (limited/mpeg/tv
range) by compressing 8 bits into 7.77 bits, which doesn't mess with
the image contrast, but leads to extra color banding. What I am trying
to do is to find a way to skip this extra step by doing the compression
into 7.77 bits of dynamic range by myself from the cinelerra's 32-bit
float RGB.
