#20 Using iMovie to Capture for FCP edit
Shane’s Stock Answer #20:
iMovie handles the media differently from FCP, specifically where audio is concerned. So it is not a recommended workflow. Here’s why…
iMovie captures using DV Stream (.dv) standard which does not use timecode. That is a big disadvantage over the way that FCP captures in that you can’t go back and recapture the material at a later date if you need to revisit a project.
The DV/NTSC specification (the one FCP uses) also calls for seperate tracks for audio and video, even if you capture it as one clip. iMovie’ DV stream format is muxed audio and video, which means that they are tied together (I can’t get into specifics because I ain’t no engineer or programmer). FCP is a bit more demanding and captures the seperate audio/video tracks, either in a single media file or as seperate video and audio files. With FCP you could capture video only or audio only because each is defined by the DV specs. while with iMovie you can’t.
Also, if you drop the iMovie footage into the timeline, your will get the RED render bar forcing you to render the footage in order to see it…
