I've got some longer format videos with audio. In Avenue 3 they play back with perfect sync to themselves (the single clip's audio and video stay sync'd up.) In Arena 4, they are off immediately, and seem to get worse and worse as it plays, lipsync is completely shot.
Note that this is a single MOV file, not separated audio/video. And that Avenue 3 shows no issues with the same files.
The clips are set to timeline sync.
