If optimized for iOS the movie will be flattened and result in an opaque black background. The movies have been recreated using the ProRes4444 codec so they will retain transparency with OS X Keynote 6 (and 5). Includes opening and closing curtains. These are the same QuickTime curtain animations that come with Spotlight and Spotlight HD but in different colors. Just drag or insert, resize to slide, center it and you are ready for a big opening... and closing! Available for standard and widescreen presentations, individually or in a package of all 9 colors for a discounted price.
