On the Insert menu, point to Movies and Sounds, and then click Movie from File. Choose the video you want to use and then click OK.

PowerPoint does not include the video in the actual presentation file (.PPT). It only creates a link. It's a good idea to put the movie file in the same folder as your PowerPoint presentation. If you later move the PowerPoint presentation to another PC or folder, copy the movie too. Keeping your movie in the same folder as your presentation guarantees that the link will still work. If you plan on distributing copies of your presentation, you should consider using the Package for CD command on the PowerPoint File menu.
