Hello Rodman Flender
I see you have not marked your question "Answered" yet, so you might want some other input after you try Graham's good ideas. If you don't already have resolution, when you post back, please key your answer numbers to the following questions. The additional info may help us offer more specific suggestions.
(1) Try playing one of your saved PB clips back with the QuickTime Player. Is it equally out of sync when played back in QT? Does the sync delay seem constant throughout the clip, or some parts of the clip better than others? How may seconds would you estimate the "wildly out of sync" delay to be: a quarter-second, two seconds, ten seconds, etc.?
(2) If you were not in a brightly lighted room when you noticed the problem, try restarting your Mac and, with no other apps running, and with LOTS of light, try another PB video recording to see if that works better.
(4) Photo Booth is a basic, "fun", application, so it is not unusual for PB-recorded audio to be slightly out-of-sync. However, iMovie files played back in the QuickTime Player should be accurate. Testing that can help determine whether your problem is unique to PB or might indicate that your Mac or your file system needs attention.
Try making a similar length video recording of a similar subject in good light using iMovie. Is the iMovie recording better synced than the PB playback of the PB recording? If you notice a delay in iMovie, too, what is your estimate of the iMovie delay in seconds?
(4) Also, save (share) the iMovie recording and play the saved file back with QuickTime player. Is the saved iMovie video better synced during QT playback?
(5) Use
Get Info on your iMac's hard disk. Post back your "Capacity" and "Available" space numbers so we can rule out a lack of disk space as a contributor.
If necessary, we will try to offer other suggestions based on the additional details you provide.
