Maybe I have to use Windows to get a decent video editor :-/ you will have the same problems. some notes: * your file is very large. Can you record some example of 5 or 10 s and post them somewhere for we to try? * I can't verify right now, but I'm reasonably sure ffmpeg can extract all video and audio from ant file * I think (only?) mkv can have several audio tracks When demuxing, all the tracks have the very same lengh (about time, not size, of course), so they can be worked on easily it may be easier, then, to move them to mp4, for example, before editing to have the smaller file possible, because, of course, you can't edit the tracks separately :-( jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
