Re: [x265] [PATCH 1 of 3] Chroma QP Offset: increase chroma QP when psy-rd is enabled

This is primarily a visual quality improvement/psy-rd hack. In 444, since chroma resolution is on par with luma, and our eyes arent very sensitive to chroma, we increase the chroma QP so that those bits can be used up in luma. On Wed, Jun 25, 2014 at 4:35 PM, Derek Buitenhuis

Re: [x265] [PATCH 1 of 3] Chroma QP Offset: increase chroma QP when psy-rd is enabled

In a sense, psy-rd encapsulates all those r-d algorithms/tweaks/hacks that improve visual quality but may hurt objective metrics like psnr/ssim. In 444, this qp hack is likely to hurt objective metrics, hence it's turned on only if psychovisual improvement is desired. On Jun 25, 2014 7:02 PM,
