luminance masking Luminance masking is a 'psychosensory' setting that is supposed to
make use of the fact that the human eye tends to notice less details
in very bright parts of the picture.
Luminance masking compresses bright areas stronger than medium ones,
so it will save bits that can be spent again on other frames, raising
overall subjective quality, while possibly reducing PSNR.
