What’s the best way to integrate all the subtitles into the corresponding MKV file?
Console batch file for mkv merge should do that as long as subs are named same as video files (or something consistent like that name +subs).
You’d want to target the sub files not idx. If that fails I’d just do an intermediate step of merging the sub and idx files into an mks file then merging that into the mkv. The gui only needs the sub files added. I’ll try and come back to this though someone else already posted a script that should be able to be adapted to do this.
