Has anyone else had this problem when using their ipad2 video camera? I sometimes get black flashes across the screen as if part is being shown as negative. For example I was recording the view across some fields and the clouds turned black for a second or two. This is also visible on playback. The black flashes always seem to take the shape of something and are not just random marks. Very annoying. Has spoilt a few home videos of my 6 month old.
