Re: [LAU] OT - syncing partially out of sync video and audio in existing files

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.
