Introduction

One thing that I have learned over the years of audio sync issues is that there is not a "catch all fix". Some fixes work for certain people and others are left in the cold. The first most import thing is make sure the basics are good:

• Make sure your drive has "free space" more than 5 gigabytes if you plan on making a DVD and preferably more.
• If you not running Panther or better make sure your drive is defragged, as it is built in to the OS now.
• Quit as many CPU hogs as you can while exporting.
• Be sure your caches have been cleaned out recently, your disk has the proper permissions, and that you have checked the integrity of the disk with the Disk Utility in the past few weeks.
• Make sure your on the lastest version of Quicktime. Here is what Apple has to say about that.
• Make sure your audio is 16 bit and that you did NOT record in LP (long play) mode with your camera.
• If using a Digi 001 with protools, uninstall digiDesign core audio manager and the problem should go away.

Try This First

Select all the clips and extract all the audio out of them and then export/make DVD.

Try This Second

Export out the whole project as a self contained movie

Then drag that movie to iDVD or for use with Quicktime

Try This Third

If you do not mind adding chapters to you movie (or already have them) put a one (1) or two (2) second break in where the chapter markers are. You can do this by; selecting a clip in the timeline view and dragging it to the right. (Watch the playhead for seconds and frames)

Last Ditch Effort

1. In QuickTime Pro, export the audio track, as an 48 kHz AIFF file
2. Make a copy of your project (using the finder) copy the whole project folder.
3. Open the copy of the project and make sure all the audio is extracted.
4. Select all the audio and delete it.
5. Export out your project as a self-contained movie
6. Open the audio (AIFF) file in Quicktime Pro (Edit > Select All, Edit > Copy)
7. Open up the self-contained movie of your project make sure the playhead is add the beginning and add the audio back in scaled (Edit > Add Scaled).
8. Save as self contained movie.

• If that does not work for you I do not know what to tell you but, call Apple. I really do not have any other answers. If I ever do I promise to post them. Oh.. I have never had this issue in Final Cut Pro and I have heard the same for FC Express.
