Any multi part splitter for mp4?

[Bencuri]

I have many episodes of a series recorded in 1 long mp4 file. Is there any fast way to fragment it to pieces by episodes? I am thinking of something like I add at what time the episodes start and the software goes through the list of and do the splitting automatically from the long file. Is there anything like that, or any splitter I can get can only produces two files at maximum?

You can create chapters for each episode and then use MKVToolNix to split them to individual episodes.

Use the batch file that @pcspeak created, it is excellent.
