This is bad. Postprocessing should always be done before cropping
unless you really know what you're doing. Remember, -vop filter order
is backwards. This will be fixed when -vop is replaced with -vf,
No wonder it's slow, you're grabbing rgb and converting it back to
yuv!! Leave the default outfmt of yv12.

FFmpeg's lavc would be a lot faster than xvid (and same or better
quality), but I assume you're usign xvid with transcode too so it
shouldnt make a difference to speed relative to that.
