Placing a picture frame around a movie is an attractive way to display it on a slide. To add a picture frame, use the Stroke settings in the Graphic inspector.
Select it, and then click the Inspector button in the toolbar to open the Inspector window. Click the Graphic inspector button in the Inspector window.
Choose Picture Frame from the Stroke pop-up menu.
Click the picture frame that appears below the Stroke pop-up menu, and select a frame style.
Drag the Scale slider or specify a percentage to set the thickness of the picture frame.
When your movie plays during your slideshow, playback controls appear when you move the pointer over the movie. To learn more about controlling the playback of your audio or movie during your presentation, see Playing Movies.
