Background Video Instead of a photo background, you can also create moving, animated, video back- grounds, just like the ones you fnd on many commercial Hollywood DVDs. It's far easier to customize your background video than, say, to administer anesthesia to yourself and then extract your own teeth. Note: In all, iDVD provides three different places to install movies onto your menu screens. The following instructions pertain to only full-screen background videos. Don't confuse video backgrounds with drop zone videos or button videos. Changing Backgrounds Before you delve into this exciting new career, keep these points in mind: · Yourvideowillloop. Your background video fle will play, then restart and play again as long as your audience leaves the menu on the TV screen. There's no way to make a video play just once. · iDVDaddsbothvideoandsound. When your imported background video con- tains a soundtrack, that sound becomes the new soundtrack for the menu screen. It wipes out whatever music came with the theme. · iDVDhandlestiming.iDVD automatically adjusts the Duration slider (at the top of the Settings pane) to match the length of your movie. power users' clinic Designing Video Loops in iMovie Background videos don't have to jump between the end of one play-through and the beginning of the next. If you're willing to take a little time in iMovie, you can eliminate sud- den visual changes that create unpleasant jumps. Consider these techniques: Fade or Wash In and Out: Create a smooth fade out at the end of the movie clip, and a smooth fade in at the beginning, using the Fade In and Fade Out transition styles described in Chapter 6 (or, if you're partial to white, Wash In and Wash Out). Use Cross Dissolve: If you prefer, you can design your movie so that the end cross-dissolves into the beginning each time it loops. Move the playhead to 4:02 seconds before the end of your movie. Choose EditSplit Video at Playhead to break off that 4-second segment into a clip of its own. Now drag this 4:02-second clip to the front of your movie, add a 4-second cross-dissolve between the transposed clip and the start of your movie, and save your work. You can choose a different length for the crossfade; just make sure that the transposed clip lasts at least two frames longer than the desired transition time. This method works particularly well on stock footage, such as wind-swept grass, fsh in an aquarium, and so forth. You may discover a couple of drawbacks to this method. First, the start and end audio and video will overlap, and you may not like the results. Second, the background video will, unfortunately, start with the crossfade. There's no way yet to make it start playing from an un-crossfaded spot--iDVD 6, perhaps? chapter17:designingidvdthemes 423
