Description wwjd 2009-10-31 11:51:06 UTC 
I'm using pitivi on ubuntu karmic 64bit. Works pretty good, but after encoding to vorbis/theora audio and video gets out of sync.

I created a little project, which reproduce the problem:

Pitivi project file: http://dl.getdropbox.com/u/336436/a-dur/a-dur.xptv
Exported video out of sync: http://dl.getdropbox.com/u/336436/a-dur/a-dur.ogv
Imported Videoclip (DNxHD): http://dl.getdropbox.com/u/336436/a-dur/a-dur.MTS.mov
Original AVCHD-Clip: http://dl.getdropbox.com/u/336436/a-dur/a-dur.MTS

I transcoded the MTS file with ffmpeg with following options:
-s 1920x1080 -r pal -b 36000k -threads 2 -vcodec dnxhd -acodec copy

I can't reproduce this bug with git pitivi and git gstreamer.

I didn't use the *exact* same timeline, but I transcoded the file you used to 192x188 jpeg because it would take too long to decode/render and kept the original audio track as-is (AC3 6 channels).

You might want to try the updated gst-plugins-good/bad packages from the gstreamer-developers PPA, that might be the source of the problem.

If not... you could *also* try pitivi git.

Well, as I seem to be affected from the same problem, please tell me if there's any info I could provide (debug log of some kind, etc.).
Comment 4 Kenneth Mokkelbost 2009-12-17 21:35:44 UTC 
Using gstreamer from ppa and pitivi from git I experience loss of audio sync when rendering with higher audio bitrate than what the sources have, ie rendering with 48kHz from 44.1kHz sources result in sound being too early.
Comment 5 Jean-François Fortin Tam 2010-11-26 04:24:18 UTC 
The files linked in the original description are not available anymore, and this is on an obsolete version of pitivi. Furthermore, I am suspecting that this may be bug #632418.

If you can still reproduce this with the latest version of pitivi or pitivi git, and you are not using still images in your timeline, reopen this bug.
