I'm editing a project for a client who sent me a disk with 3 mpg files on it. They are the same files but large, medsium and smaller files. The files contain ad spots, and a 4 minute video they wish to incorporate into the show. How do I import these videos into m1008.2.1 with the best quality? (I'm using a 720 program, and the final edited video will go out on a DVD. Also, how do I get the audio into the m100 so it can be synced with the video? Thanks so much!
