Office Mix and STAMP: 2 Ways to Add Captions in PowerPoint

Updated: June 1, 2021

Microsoft PowerPoint has released a new feature that can be used to add captions and subtitles to PowerPoint presentations.

Office Mix for PowerPoint

Office Mix is a free add-on with the MS Office suite, compatible with PowerPoint versions 2013 and 365. It lets you integrate rich media into your slide deck, like screen-captured recordings, audio narration, and animated markups on your slides. These enhanced presentations are called “mixes” and can be stored on the cloud and shared with the public or members of your organization. Check out our step-by-step instructions for adding captions with Office Mix.

STAMP for PowerPoint

If you have an older version of PowerPoint (2010), you’ll need to use STAMP to caption your presentations. STAMP, or Subtitling text add-in for Microsoft PowerPoint, is another free add-on designed to help you add captions in PowerPoint. This tool adds an “Add Captions” function to your program so you can upload caption files in a specialized PPT XML format. Check out our step-by-step instructions for adding captions with STAMP.

Adding Captions to PowerPoint

If your PowerPoint presentation includes audio, make sure to transcribe and caption the speech to make it accessible to a wider audience. This is especially important if the deck is being used for educational purposes, since institutes of higher education are often required to caption videos for legal reasons.
