Hi,Nigel Askew, sorry to hear you encountered such problem. When we spend time and money for good .mov files from other video formats, but at last we just get the bad converted video. I hate this, and I just encouned this days ago. So you don’t need to be mad at this, it always happens. I’m a layman for transfering videos, but I’m so lucky to get good freeware named iWisoft Free Video Converter, it helps me to convert any video to mov. And it allows to change codec, video size, crop, trim etc. I like it.
