honestly I haven't done a lot of recording, but I have done some and it has been amazing, as are the photos. have you turned off scene optimizer completely, It is likely to do nothing but I always find it interferes more than helps. and of course, I'm sure you have, but have you updated the software? Settings >> Software Update >> Download and Install- if there is an update available it will show as "What's New" if it is up to date, it will say just that.
