FWIW, every time a camera or video recorder comes anywhere near an aeroplane which I am flying, all sorts of disasters occur, which are neatly recorded for the subsequent board of inquiry! As a consequence, I have banned their presence from the cockpit. As a result, all my sorties are now perfectly flown and incident free. Oh, and they all record with minute detail, always in focus with no camera shake or wobble; indeed, the finished product always seems to be professionally finished, so you needn't have any worries on that score....
