Movie Toolbox: Previews

This chapter describes the functions your application can use to create and display movie posters and previews, and also to extract still pictures from movies. A poster is a single image from a movie, while a preview is a short excerpt (sometimes as short as a single image). A preview is normally displayed as part of an Open File dialog box, and may be something other than an image, such as a sound.

This chapter also documents functions of the Movie Toolbox used to create QuickTime pictures from movies, tracks, or posters.
