If you're using lavc, checkout the vrc_override option in the manpage
that allows for specified quality for specific frame ranges.  I haven't
tried it yet but I've noticed lavc produces very blocky images with
some isolated scenes... moving water, lots of movement in the whole
frame, dissolves when the light changes a lot...
