To insert a movie into a PowerPoint presentation, use the Movie from File option on the Insert menu. If the presentation is located anywhere in the file path at which the movie file is located, PowerPoint stores the movie file as a relative path in the presentation. If the presentation is not located at the path at which the movie file is stored, PowerPoint stores the movie file as an absolute path in the presentation
Insert a movie file as an object
When you insert a movie as an object, PowerPoint is not involved in the process. The process occurs in Microsoft Windows Media Player. Windows Media Player has a set of APIs that PowerPoint 2003 uses primarily for movie playback. Windows Media Player keeps its own set of codecs. And, it uses the Windows registry file types to determine which format and codec to use. Windows Media Player looks for a codec signature in the file and then matches the codec that it finds. If Windows Media Player cannot find an appropriate codec, it searches the Web for a valid codec.
Use the Wmp.ppa add-in
By default, when you use the Wmp.ppa add-in to insert a movie file into a PowerPoint presentation, PowerPoint stores the movie file as an absolute path in the presentation. If the movie file is not in the absolute path, the movie does not play. The add-in also contains an option that you can use to copy the movie file into the same folder as the presentation. When you use this option, PowerPoint stores the movie file as a relative path in the presentation. When you play the movie file in the presentation, PowerPoint looks for the presentation in the folder that is defined when the presentation is created. If the movie file is not in that folder, the movie will not play.
We do not recommend that you use this add-in if you are using PowerPoint 2003. PowerPoint 2003 uses Windows Media Player to play most movies.
Insert the movie as a package
You can insert a movie file as a package in a PowerPoint presentation. To do this, follow these steps:
1. On the Insert menu, click Object.
2. Click Create new, and then click Package under Object type.
When you insert a movie as a package in a PowerPoint presentation, the movie file is kept inside a package that is embedded in the presentation. If you move the presentation to another location, the package is also moved to this location.
