We have to deliver a few HDTV ad spots to a video post house for striping. They require delivery on ADAT, DV-824 or 8-track BWF. The channels within an 8-track BWF should be labeled as in a DV-824 file. I can output 7.1 BWF from the Pro Tools session without a problem, but what I need now is some way of going into that file and labeling the individual channels to suit the post house's standards. At least, that's what I got from a slightly technically-challenged machine-room underling at the post house.
