Preview a movie or animated GIF in a presentation

In normal view, display the slide, and click Slide Show in the lower-left corner of the Microsoft PowerPoint window. If you set up the movie or animated GIF to play when you click it, you'll have to click it to play it. (Or, if you've inserted a movie as an object to play in Microsoft Windows Media Player, you may have to click Stop, Start, and Pause buttons.)

Notes

You can also preview a movie in normal view by double-clicking it.
If your movie or animated GIF is part of a custom animation sequence, you can preview it by clicking Play in the Custom Animation task pane.
