Step-by-Step Instructions

Automatic Captioning in Kaltura

To ensure your videos in Kaltura are automatically captioned, do the following:

  1. Upload your video to Kaltura. If it’s a Zoom recording, Kaltura will use the Zoom Audio Transcript for captioning (Note: the Zoom Audio Transcript must be enabled). For other videos, Kaltura REACH provides automatic captioning.
  2. Be aware that automatic captions may not always be accurate. For critical content, consider using the Technology Equity and Inclusion department's captioning service, though availability may vary.

If your video did not receive automatic captions, you can request them through the Caption & Enrich menu:

  1. Go to My Media from Kaltura or Canvas.
  2. Open the video without captions.
  3. Select Actions [1] > Caption & Enrich [2] > Order Captions & Enrichment Services [3].
  4. Select the appropriate captioning language.
  5. Select Submit to generate captions [4]. This process can take a while, depending on the length of the video.

Reviewing Caption Edits

After editing your video's captions, it’s essential to review your changes:

  2. Watch it in its entirety to ensure the captions accurately reflect the audio content and are properly synchronized.
  3. Make any further edits if necessary to ensure the highest quality captions for your viewers.
