 Same as the aspect option, but automatically computes aspect, taking

-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.
