Are you having video or audio playback issues?

Are you having video or audio playback issues?

To avoid playback issues when your PowerPoint presentation contains audio or video 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 slide show will play correctly. See also: Video and audio file formats supported in PowerPoint and Requirements for using the PowerPoint YouTube feature.

Important    Certain older video file formats may not compress or export properly in Office on a Windows RT PC. Instead, use modern media formats such as H.264 and Advanced Audio Coding (AAC), which PowerPoint 2013 RT supports. Want to know what version of Office you are using? And see: Requirements for using the PowerPoint YouTube feature.

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

  1. 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. If it doesn’t appear, you don’t have compatibility issues.Click the Optimize Compatilibilty button

  3. Click Optimize Compatibility.

  4. Below, PowerPoint improves any media that requires optimization.

Optimizing media files for playback

Notes    When the Optimize Compatibility button 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 or later (and if the files were linked, they will be embedded), on the File tab, click Info, and then click Convert.

Are you having trouble inserting or playing media?

If you are having trouble inserting or playing 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 on your computer. The best solution is for the author to run Optimize Compatibilitybefore sending the file to anyone else.

And, when attempting to insert a video file, you could receive an error message like this if you do not have the associated 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.
