Adding Animation, Sound, and Movies to Microsoft® Office PowerPoint® 2007
Animated text and graphics add interest to your slides. You decide how and when the animation occurs.
Avoid abrupt transitions by having one slide smoothly replace another. You can control the transition type, its speed, and when it takes place.
Audio and video clips can convey information or simply add interest. Use sounds and animated clips that come with PowerPoint, or supply your own audio and video files.
After you insert an audio or video object, you can change the way it plays by modifying the animation or action settings.
