The tradeoff, of course, is video quality. Higher bit rates generally provide clearer and more accurate picture reproduction than lower bit rates do, especially in action scenes. If the bit rate of a DVD is very low, you get blocky-looking, unclear video. But iDVD's "lowest-quality" mode--4 Mbps--is still above the minimum bit rate needed for clear video for home movies. Don't constrain yourself needlessly to the 60-minute format until you've given the Best Quality format a try. Phase 5: Burning Your DVD Burning Your Project When you've fnished editing your disc and testing it thoroughly, it's time to proceed with your burn. This is the moment you've been working toward. Note: The following steps walk you through the process for burning with an internal Apple SuperDrive (or equivalent). If you want to burn your discs to an external drive, see page 450. 1.MakesureiDVDisreadytoburn. Part of iDVD's job is to encode (convert) your movies, music, and pictures into the MPEG-2 format required by standard DVDs. Therefore, it's a good idea to open the Customize Drawer, click the Status button at the top, and make sure that the word "Done" appears next to each asset. (Apple uses the term "asset" as shorthand for "picture, movie, soundtrack, or what have you.") See Figure 15-19. Tip: If iDVD doesn't say "Done" for all assets in the list, and yet it doesn't seem to be processing them automatically, make sure you've turned on background compression. Choose iDVDPreferences, click the General button, and turn on "Enable background encoding." The only time you'd want to turn off background encoding is when you discover that it's slowing down your Mac as you work. Figure 15-19: Look for the word "Done" to the right of each asset. If a status bar appears instead, let iDVD 5 continue encoding until "Done" appears. There's no further action you must take. iDVD encodes in the background without any intervention. chapter15:fromimovietoidvd 379
