Request Machine Captions for Kaltura Media


All videos added to Kaltura ("My Media" in Canvas or MediaSpace) after 13 June 2020 automatically have machine captions added to the entry. Kaltura entries resulting from the integration with Zoom bring Zoom's machine-generated captions with them.

If the conditions are right (see the "critical concepts" section below) Kaltura media owners and co-editors can request machine captions for their Kaltura entry.

These instructions apply to all UCSD Kaltura users (instructors, students, and staff with active directory credentials).

Users can request machine captions in both Canvas and MediaSpace.
