Yes, I forgot softskip... but I thought -mc 0 is enough to prevent frame
skipping, since I'm leaving audio track intact. I mean, why there should
be skipped frames anyway? Probably I was wrong.

No... But I found one of the reasons. The broken input file? Hm... It's
NTSC DVD of Avalon, looks OK to me.
I was able to raise overall quality of the picture, lower the bitrate a
bit and get rid of half of "Bottom-first field" messages when I stopped
using filmdint's "crop" feature and replaced it by regular crop filter
after. Maybe filmdint cropped video in the beginning and then had some
problems because of it.
