I am trying to use the Trim feature in UniFab Converter (that absolutely does not work - but more on that in another thread). since all I want to do is remove a snippet of video at the beginning, I am looking for a Passthrough option so that UniFab does not screw up my video. Not there anywhere I can find.
In fact, the ONLY time I have seen the new Passthrough feature is when I was testing an mkv file. I cannot believe what a horrible mess this lousy software is!
