Create an unlimited number of scenes, which are like chapters in a book, and then link the scenes together either sequentially, or through menu-driven button links. A typical scene includes up to 100 objects: video, pictures, buttons, graphics, animations, 3D, narration, MIDI, MP3, CD music, text and VR. This leverages QuickTime s powerful compression/decompression architecture, leading to smaller file sizes, higher-quality video, audio and photography, and reduced memory requirements.
