I notice that sometimes a video will have like an aurora of light, and it will move back and forth around someone's head and other features in the video. I can have the same video playing on both decks, and one deck will have it. I have all effects off. If I restart MixEmergency, it may or may not re-appear. But eventually it may come back another session.
