Hi Christian, I have just tried your video with osgmultiplemovies with svn/trunk but it comes out black. I run the same movie in osgmovie it comes out fine though. No stats though so doesn't reveal any particular problem.
I'm not the author of the ffmpeg plugin so I can't provide any particular insights off the top of my head. Robert.
