The one you'll notice frst is the new shape of the iMovie monitor window, and the new shape of the captured clips. As you can see in Figure 4-9, they're wide instead of square. Welcome to the HDTV age, baby. You'll notice another difference, too, once you start importing: Your Mac probably isn't fast enough to capture this massive amount of data in real time. (Remember, high-defnition footage is three or four times as massive as standard DV.) That's why, if you inspect Figure 4-9 carefully, you'll see the tiny notation "Capturing HD at 1/4 speed" just above the volume slider. This notation changes as the importing process chugs along; it may say "Capturing HD at 1/8 speed" or, if you're lucky, even "Capturing HD at full speed." Tip: If you make your iMovie window smaller--small enough that the Monitor window is only a quarter its usual size--you get much better speed. iMovie, in that case, transcodes the high-def video at only a quarter of its normal size (see the box on page 103), and you get faster, smoother playback and quicker importing. (If your machine is anything slower than a dual-1 gigahertz G4 or G5 processor, in fact, you always get this quarter-sized video, unless you change the Playback settings in iMovie's Preferences dialog box.) Four Special Cases The bottom line, though, is that importing high-def footage isn't a real-time opera- tion, as it is when you import standard-def footage. Even after the camera is fnished
