Hi, ... I'd like to fix some videos that have partially out of sync video and audio, meaning that beginning at a certain point in the video the audio is suddenly out of sync by a couple of seconds. There's no constant change, the delay seems fixed once it's there. I wonder how to fix such a thing. The files are xvid encoded videos and vbr mp3 audio inside avi containers. I thought it should be reasonably easy to cut and move the audio (re-encode if unavoidable, but I know it's in principle possible without) and put it back in a container, but I didn't manage. Can someone recommend a program/workflow that would allow this? I tried: - Avidemux: ... - openshot: ... - kino: ... - openmovieeditor: ... - cinelerra-cv: ... - pitivi: ... - kdenlive: ... I thought it would be a simple task, really nothing fancy. Seems like I was wrong. Regards, Philipp Phillipp, I had a problem with out of sync audio using a camera that recorded using VBR. Avidemux was able to fix this with Audio/Build VBR Time Map http://www.avidemux.org/admWiki/doku.php?id=using:vbr_mp3 I can't move or stretch audio in Avidemux, but this time map function fixed my out of sync problems. -- Jeff
