Problem with WMV files with longer audio than video

Post by Jumpe » Tue Jun 23, 2009 4:44 am

I have some WMV files that contain an audio track few seconds longer than a video track. These videos play correctly, for example, in Windows Media Player and Media Player Classic (audio and video are in sync). However, the problem is now the following: when I try to convert these WMV files to MP4 the audio and video became out of sync. In these converted MP4s the audio and video are in sync in the beginning, but when the video is near the end then the audio and video are out of sync by (those) few seconds (which is the difference between the audio and video lengths).

I have tried to solve the problem by varying the framerate of the video track, but that seems not to give any help. So, I think that the problem is the difference between the lengths of the audio and video tracks. Any ideas, how to solve this problem?
