@Sir Didymus
I'm sure the topic is absolutely complex and I know (and appreciate) the scrupulous way you have developed BatchMux. No hurry, take your time, when the update will be ready, we will be here.
And, sure, from my side the list is complete. I don't know if other users would require anything else...
@rendez2k
I would use Avidemux:
- load the mkv
- trim the first minute
- select Copy Video and Audio (default)
- select MKV as output format
- save
Avidemux could eventually fix mkv muxing errors (if any).
Bye
