h264 video in what container? mp4,mkv,etc

Try WinFF, but only in one of the XVID modes. I used to use Super, but WinFF gives better results.

if the file is in a mp4 container use a program called yamb, works like a dream.

some of them are in mp4 container, however I have .mkv videos encoded with h264 too. I think I don't have Xvid's encoded with h264
Yamb works fine thanks. Can I use it from command line?

And I prefere tools that pastes the streams, and do not re-encode. Is AviDemux good for that, by the way?
thanks

yamb uses the command line tool mp4box so use it. Try mkvtoolnix for mkv files.

Or use avidemux, it does not reconvert.
