Yes, for -l4 and -l5 high compression settings I have saved a lot of bits
on UV chroma planes, more than the other codecs I think... But I still find
that saving on UV chroma planes and giving these bits to Y luma plane is
still more efficient visually... According to my tests, eyes (at least
mine) are a lot more sensitive to Y luma plane than UV chroma planes.
With this processing, I find that now the -l4, -l5 high compression
settings of the NHW Project are better than x265 (HEVC)!
What would you think of this increased compression of UV chroma planes?
