The video rendered by PD11 appears to have an offset audio problem. The audio track is roughly 1/2 second delayed throughout the entire movie output. This needs to be corrected.

How can this be done using the editor? I don't see a track sync or offset adjustment. Also the audio seems linked to the video. Can it be decoupled and slid one way or the other?

Thanks.

Audio Sync is not a common problem in Powerdirector 11.

The causes are many.

Quote: The video rendered by PD11 appears to have an offset audio problem.

I'm a new user of this software myself, and have run into this problem from time to time with .wtv files that have been recorded with Windows Media Center.

You can unlink the audio and video tracks by right-clicking on the timeline and selecting "Unlink audio and video." You can then select either the audio track or the video clip and move them separately. If you zoom way in you can make very small adjustments. My sync problems with .wtvs were that the audio was slightly behind the video, and just moving the audio track about 00:00:00:05 to the right solved my problem.

Here is another solution that was provided me by a helpful person in the AudioDirector forum http://forum.cyberlink.com/forum/posts/list/29137.page
that may be applicable:

If the WTV files are prone to go out of synch during editing, it might be worth considering producing the WTV files before any editing to the desired output format - then editing the produced files.

e.g. 1. Import WTV & insert in timeline
2. Produce to MPEG-4
3. Replace WTV with MPEG-4
4. Edit video & audio
5. Produce to MPEG-4 (same profile as 2.)

That might help avoid the issue.

BillyR is correct - some video formats need to be converted to a more stable format like MPEG4 before you start editing them..
Also, PowerDirector has a bug where the audio track gets 'busted' away from the Video track all by itself. This will cause a time displacement twix audio & video.
Eg. If you drag/extend the length of a Title clip by a second near the beginning of a video, every so often, all video clips after that point are 'busted' and their audio is now out of sync by 1 second. You can't see that this has happened until you save & re-load the project.
