Split mpeg-4 movies by the chapter
Movie Splitter

You can split your .mp4 movie without transcoding using Movie Splitter – which I wrote for my own needs.

There is a demo you can download and try.



Splitting and Trimming Custom Sections

Movies can be automatically split by embedded chapter markers, halved into two, or quartered into four. Version 1.4 added the options to let you select custom ranges to be extracted – by scrubbing or through keyboard input for fine grained control.
