The VideoLAN Forums

For a particular avi file, the audio and video become out-of-sync approximately 35 minutes into the 1hr and a half movie. Is there anything I can do to correct it? I've tried re-opening the file, fast forwarding, rewinding, anything to try to create a situation where they might sync back up -- all to no avail.

Try ctrl k (audio delay up) and ctrl l (audio delay down). However if the audio and video are at different frame rates this won't hold for long.
