Preloading AVI digital video

You can eliminate the delay caused by loading an AVI digital video from disk during a Director
movie by loading it at the beginning of the movie. You can preload an entire AVI digital video (or
as much of the video as will fit into available memory) using the Property inspector.
To preload an AVI digital video:
Select an AVI digital video cast member in the Cast window.
1
Click the AVI tab in the Property inspector.

Select Preload.

load the entire movie, Director loads only what will fit into memory. If this option is turned off,
Director does not load the movie into memory and instead plays it from disk. This results in
slower animation speeds, since each frame must be retrieved from disk before it is played.

Synchronizing video and animation

To pause the playhead until a specified cue point in digital video is reached, you can use the Wait
for Cue Point option in the Tempo dialog box. You can also use this function to wait for the end
of the digital video, even if it has no cue points. Cue points can also be used to trigger events that
will be interpreted by Lingo.
The techniques for synchronizing digital video and animation are the same as those for
synchronizing sound and animation. For details see "Synchronizing media" on page 328.

Using RealMedia content in Director

The Macromedia Director Xtra for RealSystem Streaming Media (Xtra for RealMedia) adds
RealAudio and RealVideo to the media types supported by Director (Windows only), and
handles the playback of RealMedia content in the Shockwave player (Windows only) using an
embedded RealPlayer engine. Support for the RealAudio and RealVideo media types allows
Director developers to add streaming RealMedia content to Shockwave movies and manipulate it
using the standard controls available in Director. This content can be viewed by users who have
the Shockwave player and RealPlayer 8 or RealOne Player installed on their system.
