Syncs QuickTime video and audio after framerate change. Sync-Hole attempts to sync your quicktime movies by changing the framerate of sections of the video track(s), or changing the offset of the audio track. Every time you change the framerate, it (probably) makes the movie a little harder to play back for Quicktime, so try to make as few changes as possible to sync your movie. To clarify, the Anchors and the Edits are different. Entering a number to change the movie is an Edit. Adding anchors has no effect on the final movie (so add as many as you like). Also, removing all anchors does not make the movie snap back to the way it started (what it does is make the next Edit affect the entire movie instead of just the time between anchors, which you've removed).
