Rewind The Quicktime Sprite - MACROMEDIA DIRECTOR MX 2004-GETTING STARTED WITH DIRECTOR Getting Started

Digital video movies use a timeline instead of a Score. The timing of the video playback is tied
closely to the sound track of the video. For example, if the video has a sound track, the timing of
the video and sound must remain synchronized during the entire playback of the video. For this
reason, digital videos will skip frames if necessary to keep up with the sound track. On slower
computers, several frames might be skipped during video playback. This kind of animation is
called time-based. These differences are the reason you navigate a Director movie by jumping to
different frames in the movie, and you navigate a digital video by jumping to different times
within the video.
Now you are ready to add scripts to the bitmap graphic buttons for controlling the digital video
playback. The bitmap graphic buttons are a Play button, a Pause button, and a Rewind button.
For these buttons, you use some new scripting terms, including the
properties of the QuickTime sprite. By changing the values of these properties with Lingo, you
change the way the video plays on the Stage.
When the user navigates to the sound and video scene from a different scene, the digital video
plays from start to finish once. To play the video again without first leaving the scene, you need to
rewind it. You rewind the video by setting its
