A UIVideoEditorController object, or video editor, manages the system-supplied user interface for trimming video frames from the start and end of a previously recorded movie as well as reencoding to lower quality. The object manages user interactions and provides the filesystem path of the edited movie to your delegate object (see UIVideoEditorControllerDelegate). The features of the UIVideoEditorController class are available only on devices that support video recording.


Use a video editor when your intent is to provide an interface for movie editing. While the UIImagePickerController class also lets a user trim movies, its primary roles are choosing saved pictures and movies, and capturing new pictures and movies.
