Matthias,
Happy for you; but I can’t even get named tracks.
So how can you decide upon AAF import which tracks should be merged and imported as stereo?
.L and .R files, I haven’t seen these in decades. These days, we get mxf files.
And -after they have passed through Media Composer- (Industry Standard, you know) they look like this: “BAKEOFF202006020131.new.04-01”
The “new” is introduced by Media Composer, and it rips out all of the Metadata.
But that is besides the question, because you only see these after import.
Anyway, what I wanted to say is that you simply can’t know what your are merging into your imported stereo track.
