Miln has launched Movie Splitter (http://miln.eu/moviesplitter/) for Mac OS X. The US$4.99 app splits movie files into smaller pieces for easier editing and sharing.
Movie Splitter automatically detects chapter information embedded within a movie. It’s designed for owners of Canon cameras with Hybrid Auto movie digest support .
Movie Splitter takes advantage of a Mac’s multiple operating cores and queues up movies for splitting in the background. It requires Mac OS X 10.9 or higher and is available at the Mac App Store in the Video category.
