What format files are they? If you've got an unedited file of similar
length, you could try playing it with the ffplay/melt players and see if
they exhibit the same problem. Openshot uses the MLT library, which in
turn uses the ffmpeg libraries, so any problem in either of those will
manifest themselves in Openshot. There have been some recent commits in
MLT to improve sync performance, but of course these improvments will
not be in the version of MLT shipped in Karmic.

To use the ffplay/melt players you will need to install ffmpeg & melt,
then the syntax in the terminal is:

ffplay filename.avi

melt filename.avi

Bug description:
1) Ubuntu (Karmic Koala) 2) Build wizard PPA 3) Openshot 1.0.0 

I created a 4 minute video with my flip mino HD and had no problems exporting it to youtube and youtube-HD formats and uploading them to the web. But I created a 16 minute video and the video and audio go out of sync over time. This even though the original video is in sync (and when I render it in PiTiVi it stays in sync, but of course I'd rather be using openshot!). Even in the preview pane it goes out of sync, and it stays out of sync in the exported video.
