Thanks Steve. I think I now have a clue into the world of demuxing. What sort of source material should I try and find where that needs this technique on it's way into iMovie 3 so I can practice learning to do this? You know where there are any docs for Extractor? Is it better to demux the audio into AIFF or is the MP3 choice just as good? Are we demuxing one sort of video type into the DV format? Is that the idea? Or are we demuxing into another video format? When and why? k On Thursday, February 6, 2003, at 11:40 PM, Steven Rogers wrote: > On Friday, February 7, 2003, at 01:35 AM, Thubten Kunga wrote: > >> Is there a keystroke combination to move the audio track a frame at a >> time in either direction? > > When a video or audio track item is select, the arrow keys will move > it a frame at a time.
