That's great Julian! Thank you for your response.
Anybody have anything on the workflow of how to squeeze the footage to 3.1:1 (or 3360x1080 or 1920x617)? It seems that FCP has anamorphic settings... but in choosing say "DVCPRO 24p Anamorphic" in the settings... nothing happens in the viewer?
Or, do I have to great a 1920x617 aspect ratio using Motion - and then bring it into a new FCP project in order to edit at the 3.1:1 aspect ratio?
