PPT98: Cannot Play Movies from PowerPoint 97 Files

When you open a PowerPoint for Windows presentation that contains movie objects in PowerPoint 98 Macintosh Edition, and double-click the movie object in Slide view, you may receive either of the following error message: -or-

This behavior occurs because the movie file has not been converted to QuickTime for Macintosh format. PowerPoint 98 Macintosh Edition cannot use the PowerPoint for Windows movie data. PowerPoint for Windows stores a bitmap poster frame image of the first frame of the movie. And, it attaches a tag that contains the full path and file name of the movie file. Because this tag is in MS-DOS or Universal Naming Convention format, PowerPoint 98 Macintosh Edition is unable to read it.

To work around this behavior, follow these steps:

1. Copy the original movie files to the computer where PowerPoint 98 Macintosh Edition is installed.
2. Open the presentation in and delete all movie objects.
3. Reinsert each movie object. You can insert movie objects in any of the following formats:
   
   
   • QuickTime (or MoviePlayer).
     
     
   • QuickTime VR. NOTE: To insert these videos you need the QuickTime VR extension, which is available from Apple.
     
     
   • MPEG videos. NOTE: To insert these videos you need the QuickTime MPEG extension, which is available from Apple.
     
     
   • Video for Windows, also called Movie Clips or Audio Video Interleave (AVI) files.

All inserted movies will be linked to your presentation. If you show your presentation on a different computer, remember to also copy the movie file when you copy the presentation. If you don't, you will just have a picture of the poster frame of the movie.

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
