When you distribute a movie, you must package your media Xtra extensions, scripting Xtra extensions, and transition Xtra extensions along with the movie. If you do not package the Xtra extensions with the movie, your users will not be able to view all of the movies content or use all of its features. Xtra extensions can be packaged with projectors, or your user can download your required Xtra extensions from the Internet.
If your user is missing an Xtra extension that Director requires, an alert appears when the movie opens. For missing transition Xtra extensions, the movie performs a simple cut transition instead. For missing media Xtra extensions, Director displays a red X as a placeholder for the cast member.
For more information on distributing Xtra extensions with your movie, see "Packaging Movies for Distribution" in the Director Help Panel.
