When I am capturing analog video using a convertor to IMovie 4.0, the format it automatically saves to is Quicktime. I am interested in compressing the video as much as possible without affecting the viewing quality and I also want to insure it DVD plays on as many DVD players as possible. With quality of playback and the burned disks ability to play on most players are the main concerns, is there a compressor I should use rather than quicktime for optimal compression? If so, the procedure in which to do so would be more than greatly appreciated. I currently have ILife. Many thanks.
