I have some home movies which originated on a HD cam and which have been edited with Final Cut then saved as mov files. As they're large (typically 1gb per minute for 1920x1080), I want to convert them to a more convenient file size (probably 10mb per minute) whilst keeping the frame size. Is QT export as H.264 mp4 the sensible option? If so at what bit rate? Is there any advantage/disadvantage in changing from mov to mp4?
