Captioning your Presentation


In compliance with the Ohio State Digital Accessibility Policy and Minimum Web Accessibility Standards, all multimedia presentations should provide captioning.

Once a presentation is created, you can add closed captions. All players will support presentations with closed captions.

Accepted file types include: Video Text Tract (VTT), Synchronized Accessible Media Interchange (SAMI), SubRip (SRT) or Distribution Format Exchange Profile (DFXP).

There are multiple ways you might create a SRT file. The simplest method is YouTube. To do so:

  1. Download your Mediasite presentation and extract the MP4 file.
  2. Upload the MP4 file to YouTube and create / export the SRT file.
  3. Once you have the SRT file, use the instructions below to upload it your Mediasite presentation.
