I shot video in low light using a Canon Vixia HF M500 on a tripod in the back of the room. The lighting and camera position were fixed throughout the shoot, but in watching the footage, it seems the camera attempted to auto-adjust for exposure - it very gradually goes to very underexposed, before very gradually coming back. This happens 4 or 5 times in the course of 10 minutes.
Is there a way to correct this in FCP? So the lighting doesn't appear to change at all? (since it didn't!!!)
