Hi, sorry for the delayed answer.

I checked the stats file and didn't find any errors. I have encoded more
movies and they were all fine. Yesterday I tried the old one again and
it got much to big again. Could it be that "max_bframes=2" somehow
prevent xvid from calculating the target size right?

Regards

Alexey
