![]() One scene, of a mountainside at dusk shot from a moving car, did contain compression artifacts that weren’t in the shorter movie, possibly because the clip’s content was noisy to begin with.įor schools and offices that can’t afford to supply everyone with SuperDrive-equipped Macs, iDVD 4 can now run on any Mac with a 733MHz PowerPC G4 processor or higher. (Unlike the Best Performance encoding setting, which begins encoding your DVD assets in the background while you’re designing the project, the Best Quality setting doesn’t start encoding until you click on the Burn button.) The video quality, however, was indistinguishable from that of the shorter project in most aspects. ![]() By comparison, burning a 118-minute project at the new Best Quality setting required 4 hours and 40 minutes. In my tests, burning a 48-minute iMovie project at iDVD 4’s Best Performance encoding setting (which is equivalent to the encoding scheme in iDVD 3) took roughly 50 minutes on a 1.25GHz PowerBook G4. iDVD 4 adopts the same MPEG-2 encoding technology that Final Cut Pro uses, which translates to not only more data per disc but also better-quality data. With iDVD 4, Apple at last breaks the 90-minute barrier, allowing you to burn as much as two hours on a DVD. I’d like to be able to rearrange the media hierarchy in the Map’s flowchart format. It’s disappointing that the Map feature is only a window to your data - you can’t actually move things around in it. But keep in mind that viewers can’t skip over the AutoPlay movie to jump to the navigation, even if they’ve seen it several times before (although they can fast-forward). Drag any media file to the AutoPlay area in the upper left corner of the Map window, and the file will play as soon as the DVD is inserted in a player. Clicking on the Map button displays a hierarchical view of the assets in your project. To do this, you use iDVD 4’s new Map feature. Naturally, you can choose your own media files for AutoPlay. It lets you play a media file before the first navigation page appears. AutoPlay and the MapĪnother new trick that adds professional polish to your movies is iDVD 4’s AutoPlay feature. To top it off, you can finally create button titles with line breaks. ![]() Also, motion menus can now be longer than 30 seconds - in fact, they’re limited only by the amount of free space available in your project.
