You can insert movies or sounds into a presentation by inserting them from the Clip Art task pane or a file. Movies can be either animated pictures, also known as animated GIFs, such as cartoons, or they can be digital videos prepared with digitized video equipment. Movies and sounds are inserted as PowerPoint objects. When you insert a sound, a small icon appears representing the sound file. When you insert a movie or sound, PowerPoint asks you how you want it to start in a slide show. You can choose to have the movie or sound play automatically or when clicked.
