Andy,

I replied to your Email yesterday and got a Launchpad Email interface
error.

This file plays with good A/V sync in both ffplay and melt, but not from
the OpenShot timeline.  The loss of sync is quick and not subtle.

Needing to re-encoding a long file so I can edit out a short clip makes
the editor a non-starter for me.

The file is publicly downloadable from the link I posted initially.

My:   FFplay version SVN-r19352-4:0.5+svn20090706-2ubuntu2

Status in OpenShot Video Editor: New

Bug description:
Similar to #509466, but have only a single high definition mp4 file on the time line and the audio gets progressively more out of sync as it plays.  Playback of the video in Totum has good a/v sync even after seeking during playback.

You can download the video here:

I thought cutting the clips of our lab from the show would be a good test for the kind of things I usually do with a Video editor for work -- produce short clips from larger sources to use in presentations.  Currently I usually  use Sony Vegas Movie Studio 7 or Premier Elements 2 depending on the original formats on my XP notebook to do this


I'm using Ubuntu 9.10 with all updates current as of 3PM CST 19Jan2010
OpenShot version 1.0.0 installed via the PPA.
