In PowerPoint for Windows, you can add closed captions or subtitles to videos and audio files in your presentations. Adding closed captions makes your presentation accessible to a larger audience, including people with hearing disabilities and those who speak languages other than the one in your video.

To read about best practices for accessibility, see Make your PowerPoint presentations accessible.

Beginning with version 2016, PowerPoint has a new, simpler format for caption files, called WebVTT. The video player in the following versions of PowerPoint can show those captions when you play the video:

  • PowerPoint 2016

  • PowerPoint 2019

  • PowerPoint for Microsoft 365

The closed captions are stored in a text-based file with a .vtt filename extension. You can create a closed caption file on your own or use a caption-creation tool. To search online for available tools and detailed instructions, type "create vtt file" in your search engine.

For instructions on showing captions when watching a video in these versions of PowerPoint, see Turn on closed captions or subtitles.

Requirements for this feature

In Office 2016, the availability of the closed-captioning feature depends on the way Office was installed. Closed-captioning is only available for Office 2016 Click-to-Run installations; MSI-based installations don't have closed-captioning features. Read the next section to see whether the feature is available to your installation of PowerPoint 2016.

  1. Open an Office 2016 application.

  2. On the File menu, select Account.

  3. For Office 2016   Click-to-Run installations, you'll have an Update Options button.

    MSI-based installations don't have an Update Options button. You'll only see the About <application name> button.

    Click-to-run installations have an Update Options button on the Account page. MSI-based installations don't have this button.

If you have an MSI-based installation of Office 2016, read the instructions in the 2013 section of this article to see what captioning features are available to you.

Create closed captions

Prepare a text-based caption file with a .vtt filename extension before adding captions. For instructions on how to create the caption file, see Create closed captions for a video.

Add closed captions to a video

  2. Select the video on the slide.

  3. On the Playback tab, click the Insert Captions button, and then select Insert Captions.

  4. In the Insert Captions dialog, browse to your caption file. Select the file and then click Insert .

  5. If you need to add another caption file, just repeat the process.

  6. Play the video and check that the captions appear correctly.

Remove closed captions from a video

If you need to edit a closed caption file that is inserted in a video in PowerPoint, you can first remove the file, modify it, and then add it back to the video. Before removing the file from the PowerPoint video, make sure you have the original copy of the closed caption file stored on your PC.

If you have added more than one caption file to a video, the following process removes all caption files assigned to the video.

  1. In PowerPoint, in the Normal view, open the slide that has the video containing the captions.

  2. Select the video on the slide.

  3. On the Playback tab, click the Insert Captions button, and then select Remove All Captions.

Tip: If you're using Microsoft 365 you can also show live subtitles, including live translation to another language if you like, of your speech as you present. For more information see Present with real-time, automatic captions or subtitles in PowerPoint.

Add captions to an audio file

To add captions to an audio file you should use the STAMP add-in.

In PowerPoint 2013 and PowerPoint 2010, and the MSI-based version of PowerPoint 2016, STAMP (the Subtitling text add-in for Microsoft PowerPoint) lets you add closed captions to your video and audio files. If you work with captioned video and audio files that already have Timed Text Markup (TTML) files associated with them, this add-in lets you import them directly into your presentation. If you don’t have a TTML file, you can add captions directly in your presentation by using the STAMP Caption Editor.

The STAMP add-in allows you to:

  • Import captions from a Timed Text Markup (TTML) file to create captions against an audio or video in the presentation.

  • Create and edit closed captions in PowerPoint 2010, 2013, or 2016.

  • Delete your closed captions.

  • Export captions to a TTML file.

  • Turn captions on and off when in presentation mode. Viewers who have this add-in installed can do this also.

  • Use a video/audio playback while editing Timed Text captions.

  • Align captions when they have moved, or if you re-size the video.

  • Import communicative text formatting information from the TTML file, for example: styling, color and alignment.

What do you want to do?
