I guess I'm probably stuck with 4.1 then unless the deblocking filter is
very good.

Any suggestions on settings? The blocks are small and usually not a huge
detriment to quality since the source is AVC and only about 2% of the
video (lengthwise) has noticeable artifacts, so I don't want the filter
to affect the parts that aren't blocky. I have some other videos that
are mostly the same except their source is MPEG-2 and the same parts are
significantly worse and the entire video could use some deblocking (most
of the video is good, but blocky parts are somewhat common, though
usually short).
