From your filter command I assume it's a 3D half side by side video. As far as i know, any operation to turn one of the view into a full-resolution video will need encoding and that process takes time. There are command line options to speed up the process, but anything high quality will be time consuming. Your best bet here is to either find what settings you find acceptable to balance quality and speed, or use a player that can fake it. (With some container it might be possible to do that through metadata but even so, finding a player that would understand it is another matter) _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
