.B (no)lumi_mask
Adaptive quantization allows each macroblock quantizer to vary inside
each frame.
This is a 'psychosensory' setting that is supposed to make use of the
fact that the human eye tends to notice fewer details in very bright
and very dark parts of the picture.
It compresses those areas more strongly than medium ones, which will
save bits that can be spent again on other frames, raising overall
subjective quality and possibly reducing PSNR.
