HOW TO: Upload existing closed captions to a presentation

If you already have captions for your video, either by creating them yourself outside of Mediasite or by obtaining them through another source, you can pair them with your Mediasite presentation by following the steps below.

Important Note: You should make any desired edits to your Mediasite video before you create and add captions. Mediasite will not automatically edit or remove portions of existing captions. For example, if a video already has captions, and you edit the video to remove the first 30 seconds of content, the existing captions will remain unchanged, meaning the captions will run 30 seconds behind the edited video. Creating and adding closed captions should occur after your final edit.

1. From within the list of presentations in your My Mediasite portal, select the name of the presentation to which you wish to add closed captions. A summary of the presentation will appear.

2. Select Edit Details in the right column. Options for editing the presentation will appear.
   

3. Select the Delivery tab.

4. Check the Audio Transcriptions checkbox.

5. Select a file, locating and choosing your closed caption file. Supported file formats include:

   • SubRip (SRT) preferred
   • WebVTT (VTT)
   • Synchronized Accessible Media Interchange (SAMI)
   • Distribution Format Exchange Profile (DFXP)

   

6. Select Save at the top-right.

7. Optionally, make subsequent edits to the captions using Mediasite's built-in caption editor.

Verify the captions have been inserted into the Mediasite presentation

1. From the presentation summary, select Watch In New Window from the right column. The player will load in a new tab/window.

2. Select the Play button to begin playing the presentation.

3. Using the player controls at the bottom, select CC to display the captions. This button will only be available if correctly formatted captions are present in a Mediasite presentation.
