Chapter 4. Creating Interactive Movies
QuickTime container files can hold much more that just audio and video. In fact, you can add entire layers of interactivity to your media. “Wiring” your movies transforms the audience’s experience from merely watching the movie play to playing with the movie while watching it.
The exercises in this chapter present basic interactivity you can achieve with QuickTime Pro.
Using Tracks
A basic building block in the QuickTime architecture is the track. Tracks are linear assets containing samples that the QuickTime engine plays in succession. A sample can be a frame of video, a beat of audio, or even a command derived from a script.
The Properties window displays the tracks and their settings.
