Service Summary

Kaltura is a video management tool that allows faculty and students to create, host, and share video and audio inside the Blackboard Courses environment. Users upload audio and video directly to Blackboard using the Kaltura Media Mashup tool. Media uploaded resides in the user's My Media Library (a personal cloud-based storage area). In the My Media library, users can choose to manage their media across all their courses, create screen recordings, or capture webcam video. Kaltura is also available outside of Blackboard on the Course Media website.


Media is retained in the system until the video has not been played (by anyone) for four (4) years. An email will be sent to the owner 30 days before a video is deleted with options to stop the deletion and retain the video for another four years. For more information, please review the Kaltura Retention Guidelines.

Faculty & Staff

All Zoom recordings created by Faculty and Staff users are transferred to the Zoom session creator's MyMedia account. For more information, please review the Zoom Recordings knowledge base articles.
