In each case, iMovie stores the appropriately compressed version of your movie in a temporary folder inside the Shared Movies folder. Here, you'll fnd a folder called, for example, iDVD, Bluetooth, or HomePage. The idea is that if you want to send the same movie out again later, you'll have a ready-to-transmit copy. You won't have to wait for iMovie to compress the movie all over again. How iMovie Organizes Its Files Cache Folder This folder is where iMovie stores little scraps and bits it needs for its own use. For example: · The Timeline movie is a lot like the reference movie described above, except that the movie is primarily for iMovie's own use. It doesn't incorporate everything you might consider an important part of the movie (for example, it doesn't include DVD chapter markers). · Thumbnails.plist and Timeline Movie Data.plist are special data fles that store in- formation about the status of your Clips pane (Thumbnails.plist) and the timeline at the bottom of the window (Timeline Movie Data.plist), like what zoom level you've selected and whether or not you've opted to display sound waves on the audio clips (see the following section). These .plist fles are for iMovie's use, not yours. Audio Waveforms Folder Audio waveforms are visual "sound waves" that appear on audio clips. These visible peaks and valleys make it a lot easier to cue up certain video moments with the audio. These graphic representations of your sound fles don't appear by magic, though. First, you have to turn on this feature by choosing ViewShow Clip Volume Levels. Then, iMovie has to compute the waveforms' shapes, based on the sonic information in each clip. Because that computational task takes time, iMovie stores a copy of these visuals in the Audio Waveforms folder, which it creates on the fy. Thereafter, each time you open your iMovie project, you won't have to wait for the waveforms to appear. iMovie will retrieve the information about their shapes from the fles in this folder and blast them to the screen in a matter of moments. (The .wvf fles are the waveform graph- ics; .snp fles store "snap to" information for Timeline snapping, as described and illustrated on page 217.) Importing Footage from Non-DV Tapes We live in a transitional period. Millions of the world's existing camcorders and VCRs require VHS, VHS-C, or 8 mm cassettes--that is, analog tapes instead of digital. DV camcorders are rapidly catching up; they're the only kind people buy these days. But in the meantime, potential video editors face a very real problem: how to transfer chapter4:camcordermeetsmac 115
