Inside Macintosh: QuickTime Components

Importing and Exporting Movie Data

Your application starts a data import or export operation by calling the Movie Toolbox. There are several Movie Toolbox functions that allow you to specify a data import or data export component. For example, the PasteHandleIntoMovie and ConvertFileToMovieFile functions allow you to specify a movie data import component. The PutMovieIntoTypedHandle and ConvertMovieToFile functions allow you to specify a movie data export component. All of these functions select a component for you if you do not specify one yourself. For more information about these functions, see the chapter "Movie Toolbox" in Inside Macintosh: QuickTime .

When you import data into a QuickTime movie, you can specify that the data be placed into a specific existing track in the movie, into a new track that is created by the movie data import component, or into one or more existing tracks (in this case, the component may create additional tracks, if necessary).

When you export data from a QuickTime movie, you can request data from a specific track or from the entire movie. In addition, you can specify a segment of the track or movie to be exported.
