I've looked at some forums for this, but I'm not a technical wizard and don't understand what they mean. Someone said it only happens in MP4 (which is the same for me) and then was told to update their gpu cards which I'm not even sure how you do that or what it would be. I need some help on this. I only noticed that it started today and it has never happened before this so I'm quite confused. I paid good money for this so I'd like to be able to film in MP4 like I want to. Thanks
