didn't turn out so good, as well as the earlier suggested vf-hqdn3d
settings - but I'm not looking for filters anyway.

Was a good hint, and

helped to understand that i need to get as many B-frames as possible.
Keyint is limited to 250 in lavc, so I tried x264, which allows infinite
keyint, or just one I-frame followed by B-frames only. It also has very
nice motion recognition and the macroblocks aren't as "blocky" and
grid-like. I tried with very low vbitrate lavc-mpeg4, but x264 just
looks better and seems to rely heavier on motion... And, additionally,
the desired effect still works with high resolutions. I can even make
the video spread into vf-expanded black stripes, just like that old
decay-screensaver.
