.TP
.B (no)dct_decimate
Eliminate dct blocks in P-frames containing only a small single coefficient
(default: enabled).
This will remove some details, so it will save bits that can be spent
again on other frames, hopefully raising overall subjective quality.
If you are compressing non-anime content with a high target bitrate, you
may want to disable this to preserve as much detail as possible.

.TP
.B nr=<0\-100000>
Noise reduction, 0 means disabled.
100\-1000 is a useful range for typical content, but you may want to turn it
