Are you having video or audio playback issues?

To avoid audio or video playback issues in PowerPoint, you can optimize media files you've inserted into your presentation for compatibility. For a list of supported file types, visit Video and audio file formats supported in PowerPoint and Requirements for using the PowerPoint YouTube feature.

Tip    Some older video file formats may work properly in Office on a Windows RT PC. If you're using that kind of PC, it's best to use newer media formats like H.264 and Advanced Audio Coding (AAC).

When you're ready to share your presentation, do the following:

  1. On the File tab, select Info.

  2. If the media in your presentation was inserted in a format that might have compatibility issues when played on another device, the Optimize Compatibility option will appear. If it doesn’t appear, you don’t have compatibility issues and are ready to share.

  3. Select Optimize Compatibility. PowerPoint will improve any media that requires optimization.

Notes    When the Optimize Compatibility button appears, it provides a summary of 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, Optimize for Compatibility will report that you need to embed them. Select View Links to proceed. The dialog box that opens will allow you to embed the videos by selecting Break Link for each link you want to embed.

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

To upgrade your media files from an earlier version to PowerPoint 2010 or later (and embed linked files), on the File tab, select Info, and then select Convert.

Having trouble inserting or playing media?

If you are having trouble inserting or playing media, it could be that you don't have the proper codec installed. For example, someone could send you a PowerPoint presentation with media based on a codec that your PC doesn't have. The best solution is for the author to run Optimize Compatibilitybefore sending the file to anyone else.

When attempting to insert a video file, you could receive an error message like this if you don't have the right codec file installed:

Having trouble synchronizing your music with your slide show?

If your slide show is longer than one song, you can add more songs. However, if you find that you are having trouble synchronizing the music with the slide show, you can use a third-party audio editing tool, such as Audacity®to string the songs together into one file so they play continuously throughout the slide show.
