Play a movie full screen
Instead of playing a movie as part of a slide in your presentation, you can play it so that it fills the entire screen. This is called playing a movie full screen. Depending on the resolution of your original movie file, the movie might appear distorted when played full screen. For this reason, it is always a good idea to preview your movie, so that if the movie appears distorted or blurry, you can undo the full screen option.
If you set the movie to play full screen and it is also set to start automatically, you can drag the movie frame off the slide so it will not be visible on the slide, nor will it flash briefly before the movie goes to full screen.
Important If you drag the movie frame off the slide or hide the movie frame, you must set the movie to play automatically or by some other kind of control, such as a trigger. A trigger is something on a slide, such as a picture, shape, button, paragraph of text, or text box, that initiates an action when you click it.
Set a movie to play full screen
In Normal view, click the movie that you want to play full screen.
Under Movie Tools, on the Options tab, in the Movie Options group, click Play Full Screen.
Preview a movie
To preview a movie, in Normal view, do one of the following:
Double-click the movie.
Click the movie, and then under Movie Tools, on the Options tab, in the Play group, click Preview.
Click the slide with the movie, and then click Slide Show at the bottom of the Microsoft Office PowerPoint 2007 window, or press F5. If you set the movie to play when you click it, click the movie frame.
If your movie is part of a custom animation sequence, to preview it, click Play in the Custom Animation task pane.
If there are multiple slides in your presentation, use the title placeholder to identify the slide that contains the movie frame, so that you know which slide to click and play.
If you inserted a movie as an object to play in Microsoft Windows Media Player, you may have to click the Stop, Start, and Pause buttons in Media Player to control your movie.
