[Frank Kruse]

It's a virtual clip made of a whole bunch of others but on a single track. Like clip groups in PT but they essentially become one clip in MC. Often a scene shot with green screen plus the plate plus whatever else so it becomes just one "brick" on a single track (unlike clip-groups in PT) which is easier to handle when editing. The equivalent of a clip group in PT containing 10 tracks that you can place on a single track like in Reaper. PT seems to fail to read these entirely from the video track in the AAF.
