This much video 1 minute 15 minutes 30 minutes 60 minutes 2 hours 4 hours Needs about this much disk space 228 MB 3.5 GB 7 GB 13 GB 28 GB 53 GB Getting into iMovie As you could probably guess, high-defnition footage is even more massive; each minute of it takes between three and four times as much disk space as standard DV footage. Note: That's "between three and four," because there are two primary HDTV standards, known as 720p and 1080i (see page 92). Video shot in 720p consumes slightly under three times the amount of disk space as standard DV (about 9 MB per second, or 34 gigabytes per hour), and 1080i takes up four times as much (14 MB per second, or 52 gigs per hour). When you save and name your project, you're also telling iMovie where to put these enormous, disk-guzzling fles. If, like most people, you have only one hard drive, the one built into your Mac, fne. Make as much empty room as you can, and proceed with your video-editing career. But many iMovie fans have more than one hard drive. They may have decided to invest in a larger hard drive, as described in the box on page 95, so that they can make longer movies. If you're among them, save your new project onto the larger hard drive if you want to take advantage of its extra space. Tip: People who have used other space-intensive software, such as Photoshop and Premiere, are frequently confused by iMovie. They expect the program to have a Scratch Disk command that lets them specify where (on which hard drive) they want their work fles stored while they're working. As you now know, iMovie has no such command. You choose your scratch disk (the hard drive onto which you save your project) on a movie-by-movie basis. Note, by the way, that digital video requires a fast hard drive. Therefore, make no at- tempt to save your project fle onto a foppy disk, Zip disk, Jaz disk, SuperDisk, iDisk, CD-R, DVD-R, or another disk on the network. It won't be fast enough, and you'll get nothing but error messages. Video format Unlike previous versions, iMovie HD offers a new pop-up menu in the Create Project dialog box called "Video format." The most important lesson to learn about this pop- up menu is that, in general, you should ignore it. Here, you can specify what kind of incoming video iMovie should expect, but you don't have to. iMovie detects what kind of camcorder you've attached automatically, and it creates the right kind of project no matter what this pop-up menu says. chapter4:camcordermeetsmac 91
