How To Split by Chapters using MKVToolnix

[mugz8391]

I created an mkv from a blu-ray using MakeMKV. MediaInfo shows the chapters were preserved but when I next try to split the file by chapters using MKVTooknix GUI it gives me an error. All I am doing is loading the file and selecting split mode "Before chapters". The error reads "Invalid chapter number '' for '--split' in '--split chapters:': Not a valid number or not positive." (MKVToolnix GUI automatically sets the chapter number to "unlimited" in this split mode).

What am I missing?

This is a music video and I want to be a able to play each song separately and mix and match with other music videos, change play order etc.

I found this on another board using the command line which works fine, its just using the GUI does not work:

mkvmerge -o output.mkv --split chapters:all input.mkv

Worked perfectly, just as expected.

You are supposed to type "all" (or numbers) into the field below the drop-down box. (If you hover your mouse over this or other fields a tooltip box explaining this will be shown.)

Ah, that's the trick! Thanks!
