I downloaded Windows Live Movie Maker yesterday to edit .MOV footage off my HD dash cam. My first edit gave me the clip I wanted, but the quality, or should I say lack of it, appalled me. I could only save it in .wlmp format and have not found any way of retaining the original quality or any other format for saving the footage. Could anyone advise, please?
