Hey, thanks everyone for the very quick and helpful replies! One question: >From: sb <videovideo at mac.com> > >Aiff at 44.1khz stereo 16 bit is the specification for an audio cd I just tried that, and got a nice audio file from it. However, because of the length of the iMovie project (nearly 2.5 hours), the resulting audio was 1.37 GB, making it too long for an audio CD. So I need to punt down one level. What are the quality and file-size differences between 22.05KHz 16-bit stereo, and 44.1KHz 8-bit stereo? Patty
