+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.
