If you know a person with hearing, sight, or reading disabilities you would know what we are talking about, STAMP (the Subtitling Text Add-in for Microsoft PowerPoint 2010) is a new, free public beta plugin for office powerpoint that increases the accessibility of your presentations by adding closed captions to video and audio files. STAMP lets you create captions within PowerPoint or import existing industry standard Timed Text Mark-up Language (TTML) files.

STAMP helps Microsoft PowerPoint 2010 users to quickly and easily add closed captions to any video and audio files included in their presentations, either by creating the captions within PowerPoint or by importing an existing industry-standard Timed Text Mark-up Language (TTML) file. If you don’t have access to an existing TTML file but still need to create captions (or adjust imported captions), you can use the simple caption editor STAMP provides.

With STAMP you can also subtitle videos or audio files in another language, for example, for a training program. Our own Office Training team is using STAMP to subtitle our training videos for audiences around the world, and to help our subsidiaries localize those videos into many different languages.

The Subtitling text add-in for Microsoft PowerPoint lets you add closed captions to the video and audio files you include in your presentations. 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.

The STAMP add-in allows you to do the following:

  • 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.
  • Delete your closed captions.
  • 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.
