From JS8 Media:
MovieChapterizer provides an easy way to add chapter names into movies you can view with QuickTime Player. Use MovieChapterizer to add chapter names to numerous points in your movies by simply moving the playhead slider and entering chapter names wherever you want. Then open the movie in QuickTime Player and the chapter popup button allows you to navigate directly to the chapter markers.
What's new in this version:
Minor adjustments for Mac OS X 10.8 Mountain Lion.
This review was originally posted on VersionTracker.com. As useful as this app could be to me, the demo is extremely unstable and/or just plain doesn't work. It's locked up on me more times than not, whether just launching the app or trying to save/export a session//movie.
When launched, the app claims there is an update for 2.96 but it just takes you to the main website and the only link there is for the same version (2.4)
