1) Is there a way I can use MKV Prop Edit to change all the titles of the video tracks to the file name (or parts of the file name?)

2) I have checked a couple of places (link 1 / link 2) about changing/deleting the file/segment part of the file as I have about 40 files with some wrong info. I couldn't get the little script to work, so I simply added --delete TEXT I DON'T WANT to the General > Extra Parameters box. However the program then says "Error: More than one file name has been given"

I have tried looking in the headers of the file but strangely, the file/segment part isn't there so I can't edit it that way and MKV Prop Edit doesn't have any other options for the file/segment text.

Any help?
