You can punch up your presentation by adding multimedia elements ”such as sound effects, movies, background music, recorded narration, and more ”to your slides. Each multimedia element, or clip, you add to a slide becomes a slide object that you can then manipulate. You can add a single multimedia object, or include several on the same slide.
You can choose from a variety of prerecorded sound clips from PowerPoint's clip-art collection, as well as animated GIF files. You can also add your own video clips, such as footage you record with a digital camcorder. You can even record your own sounds and narration to go along with your presentation, or you can instruct PowerPoint to play background music from a music CD-ROM. A few well-placed multimedia objects can really make your slide show come to life.
