Kaltura (Captioning) - Manually Requesting Machine Captions
The University of Wisconsin System (except for UW Madison) instance of Kaltura automatically provides machine generated captions at no charge for all videos added to Kaltura after December 1, 2021. For videos added to the UW System instance of Kaltura before this date or videos whose captions have been deleted, the video owner or co-editor can manually request that machine-generated captions be added.
Accuracy and Editing
Kaltura auto captions are meant for general use and are, on average, approximately 90 percent accurate.
For more information on editing captions, see the Kaltura (Captioning) - Editing Captions guide.
If captions are needed to fulfill a reasonable accommodation for disability-related access, please follow the established process on your campus to ensure your video captions are accurate and meet Americans With Disabilities Act (ADA) requirements.
Requesting Machine Captions
Here is how a video owner or co-editor can request machine-generated captions for a Kaltura video:
1) Go to Kaltura's "My Media"
1a) In Canvas, go to Canvas > Account > My Media.1b) In Mediaspace, go to Guest > Login, then [Your Name] > My Media.
2) On the My Media list, check the box next to one or more videos you'd like to caption.
3) Click the Actions drop-down menu near the top right of the screen, then select Caption & Enrich.
4) Under Order Captions, select:
- Service: Machine
- Source Media Language: English [or other language, as needed]
- Feature: Captions.
5) Click Submit.
The resulting screen will show you all of your previous captions requests for that video. You can get back to this Captions Requests screen by going to Actions > Caption & Enrich.
6) The time needed for Kaltura to generate the captions may vary from several minutes to several hours.
When the captions are ready, the "CC" button to turn on caption display will automatically appear in the video player anywhere that the video is embedded or posted (even existing embeds or shares). At this point, users watching the video will have the option to display the captions, with no further action from the video owner needed.
7) We recommend that the video owner or co-editor edit the new captions in order to improve their quality.
