I'm trying to export a multi-track QT movie, so that my clients on the other end will be able to open the mov with all tracks 1-6 laid out. I've tried assigning roles, and exporting using the multi-track quicktime option, but it always ends up collapsed into one single track.
Maybe you already know, but if you import a multi track file after export and place it on a timeline to check if everything's OK, you'll see only one audio track. To reveal all the tracks in the timeline you need to check "expand audio components".
