I don't know if this works in PT (I suppose you could import a video and export as audio...?) but in Logic I can import a video and it prompts me to import either both the audio and video or the audio only.
Just figured it out...literally just drop the damn thing right into pro tools...and yeah the vid is on my comp, it seemed like it would be a little more complex then that lol
It was just an AVI file that a buddy recorded with his "iflip" i think...if you want send the file to me and ill see what i can do with it and send it back to you
