Tip: All of the canned export presets preserve the stereo sound present in your original camcorder footage. Unfortunately, most computers don't have stereo speakers. (Only certain Mac models come with built-in stereo speakers.) Meanwhile, saving two independent soundtracks makes your QuickTime fle larger than it would be if it were saved in mono. Therefore, if creating a compact QuickTime Movie fle is important to you, consider using the Expert settings, described later in this chapter, to eliminate the duplicate soundtrack. The Share Presets ·Timetocompressoneminuteofvideo. The "Time to Compress" statistic provided below indicates how long it took a PowerBook G4 to compress a standard sample movie that's exactly one minute long. (Compressing a 10-minute movie, of course, would take about ten times as long.) Of course, the time it will take your movie to get compressed and saved depends on the codec you've chosen, the length of the movie, how much motion is visible on the screen, and your Mac's speed, but the next section offers a rough guide. ·Filesize. The fnal statistic provided for each option shows you how big the resulting QuickTime fle might be (in megabytes). These numbers, too, refer to the sample one-minute DV movie described in the previous paragraph. Email Video codec: H.263 Size: 160 x 120 Frame rate: 10 per second Audio codec: QDesign Music 2, mono, 22 kHz Time to compress one minute of video: 1 minute File size: 1.2 MB The movie you export with these settings is fairly blurry, and the size of the QuickTime screen is closer in size to a Wheat Thin than a Cineplex. Still, the H.263 video codec has two important benefts. First, it makes the exporting much faster than if you used, say, the Sorenson 3 codec (which takes nearly twice as long). Second, the resulting QuickTime fle is relatively tiny; at just over 1 MB for a minute-long movie, it's actually within the realm of possibility that you could email this thing to somebody without incurring their wrath. (The Sorenson 3 codec produces a better-looking movie. But its movies are 3.3 MB per minute--far too large for casual emailing.)
