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

  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.
