Functions for Getting and Playing Movies

Preferred Movie Settings

Every movie has default, or preferred, settings for playback rate and volume. These settings are stored with the movie in its movie file. The Movie Toolbox provides functions that allow your application to manipulate these default settings.

You can use the GetMoviePreferredRate and SetMoviePreferredRate functions to work with a movie's default playback rate. You can use the GetMoviePreferredVolume and SetMoviePreferredVolume functions to work with the default sound volume of a movie.

You can use the SetMovieRate function to change a movie's playback rate--see "Working with Movie Time" beginning on page 2-169 for a complete description of this function. The Movie Toolbox also provides a number of functions that allow you to change other settings when you play a movie. These functions are discussed in "Functions That Modify Movie Properties" beginning on page 2-142.
