Hi guys!
Thanks for your support so far! I somehow managed to get Python 2 to work..
I actually made some progress...not perfectly the way I wanted it to be, but it might get the job done. I'll post the whole script on here later, if someone is interested.
I was wondering...on the one hand there seem to be some powerful scripting possibilites, on the other hand, something simple as "GetCurrentClip()" does not exist.
I was struggling with stuff like this:
Does not work: FirstClip.AddMarker(i, "red", "Marker1", "Marker1 at frame 1", 1)
Does work: FirstClip.AddMarker(i, "Red", "Marker1", "Marker1 at frame 1", 1)
But I can't find a documentation of those attributes/arguments anywhere

Also in the Fusion script guide I couldn't find this...
Thanks!
Volker
