I'm trying to take a movie that I need to analyze for an essay and split it into 18 movie files, one for each chapter (as defined by pre-existing chapter markers), for ease of watching one scene at a time and then stopping to write about it. How do I accomplish this?
I solved this by using Handbrake.
Select the movie as the source file.
Near the upper right of the Handbrake window, there's an option to select a range of chapters. Tell it to go from 1 to 1.
Name the destination file 1.mp4, so that it can be distinguished from the other files that are soon to be created.
Start the encoding.
Repeat this process for every chapter of the movie, clicking Add to Queue so that the files will be lined up to be created immediately after 1 is finished.
Sure enough, now I've got 18 movie files that together make up an entire film!
To my knowledge, no one has asked this question online before, so I figured I'd share my answer with the world. Hope it helps someone!
I recorded a tutorial on doing this with QuickTime which I believe is a little simpler than Handbrake. Let me know if this helps: https://www.youtube.com/watch?v=g7MgVBGfFCo
Another solution, without re-encoding. If you only want to split the video into multiple files you can use mkvtoolnix . Use handbrake to find the chapter timestamps and mkvtoolnix to do the splitting.
