.IPs deblock-chroma
Activate xvid internal postprocessing filter: chroma deblock filter.
See also \-vf pp, which is faster than XviD's own filter.
.IPs deblock-luma
Activate xvid internal postprocessing filter: luma deblock filter.
See also \-vf pp, which is faster than XviD's own filter.
.IPs dr2\ \
Activate direct rendering method 2.
.IPs nodr2
Deactivate direct rendering method 2.
.IPs filmeffect
Activate XviD internal film grain effect.
Adds artificial film grain to the video.
