Optimize the media in your presentation for compatibility

The Optimize Compatibility command in PowerPoint will help you to resolve playback issues.

Resolve issues so media will play without fail

To avoid playback issues when your PowerPoint presentation contains media, such as video or audio files, you can optimize the media files for compatibility. This makes it easy to share your presentation with others or take it with you to another location (perhaps to use a different computer to present it elsewhere) and your slideshow will play correctly

  1. When you are ready to share your presentation, with the presentation open in PowerPoint, on the File tab, click Info.

    On the File tab, click Info.

  2. If the media in your presentation was inserted in a format that could present compatibility issues when played on another computer, the Optimize Compatibility option will appear.

    Optimize the media for compatibility

    When the Optimize Compatibility appears, it provides a summarization for resolutions of potential playback issues. It also provides a list of the number of occurrences of media in the presentation. The following are common scenarios that can cause playback issues:

    • If you have linked videos, the Optimize for Compatibility summarization will report that you need to embed them. Click the View Links option to proceed. The dialog box that opens will allow you to embed the videos simply by clicking Break Link for each media item that you want to embed.

    • If you have videos that were inserted using an earlier version of PowerPoint, such as version 2007, you will need to upgrade your media file format in order to ensure that these files will play back. Upgrading will automatically update and embed these media items to the new format. Once you have upgraded, you should run the Optimize for Compatibility command.

      To upgrade your media files from an earlier version to PowerPoint 2010 (and if the files were linked, they will be embedded), on the File tab, click Info, and then click Convert.

      Having trouble playing or inserting media?

      If you are having trouble playing or inserting media, it is likely that you do not have the proper codec installed. For example, someone could send you a PowerPoint presentation with media already inserted, and that media is based on a codec that you do not have installed. The best solution is for the author to run Optimize Compatibilitybefore sending you the file. Try one of the following to help resolve any lingering issues:

    • One solution is to download a third-party media decoder and encoder filter, such as ffdshow, QuickTime, or DivX, which will allow you to decode and encode a variety of formats.

    • If you decide to deliver the presentation that you created on a PC, on an Apple Macintosh, the file formats, .wmv and .wma are not native to a Macintosh computer. In this case you will need an Internet connection so that you can download a QuickTime component (for the Mac operating system) that supports Windows Media Video, such as Flip4Mac, to play these your media files.
