Thanks for answer Brandon.

I can't use higher bitrate for YouTube, because they have limit 350 Kbps. I can
hack FLV movie to upload higher bitrate movie, but I don't want to do that.

I found reson of really bad quality - it's because video is so jerky. When I do
not change framerate, video quality is ok.

The thing is I'd really like to change frame rate to 12-15 fps, because quality
can be even better.

People say mencoder has no motion compensation filter, that's why movies are so
jerky and people also say that I need to change frame rate liek this:
30 fps > 15 fps
24 fps > 12 fps
25 fps > 12.5 fps

I've tried this, but videos are still jerky. :(

I wonder is there any filter for mencoder that can fix it?

The original movie was encoded by iMovie. I wonder, why does it encoding movies
with missing keyframe? And how can I fix it?
