Prompted by the answer to Any way to edit metadata of MKV files (without re-encoding)? it appears I should be able to do this with
mkvpropedit, part of MKVToolNix.
TL:DR All I want to do is remove any title, so VLC tells me the show title & episode number, as listed in the filename - not who helpfully ripped it so I didn't have to rip all my own DVDs. I don't even have a DVD player in the TV room any more, I'm putting it all on a Mac Pro.
I've tried doing this in the GUI of MKVToolNix but it seems I can only do one file at a time & I have dozens.
My intention would be to be able to save something as perhaps a script/automator applet, to make it drag & drop in future, see if I've missed some option in the GUI editor that would let me batch edit, or indeed find another tool which is capable of batch editing.
Essentially, this is what I'm trying to achieve, just not one at a time…
Per comments, app contents…
