Last Updated: 12/09/2015


Kaltura is a rich media streaming service that supports audio and video streams.

How Kaltura is used

Desire2Learn (D2L) Integration

Kaltura has been integrated into D2L, CU-Boulder's online learning environment. This integration allows instructors and students to upload video and audio files into their D2L courses for sharing. Visit the Kaltura - D2L Integration page to learn more.

Kaltura Management Console

CU-Boulder departments or groups that need advanced control over their hosted media can work with OIT to gain access to the Kaltura Managment Console (KMC). This web-based interface provides delegated management of content to individuals within colleges, schools, departments and groups, including group based delegated administration to allow multiple people to share the management of the organization's content. Learn more.

Request Video Captioning

The Captioning service was established as a part of the campuswide Accessibility Initiative aimed at fostering an accessible campus environment. The primary focus of this service is meeting captioning needs for accommodation requests and public-facing academic content. We also provide information, consultation, and guidance for a broad-range of media and activities that may require captioning. For more information about captioning, visit the video captioning service page. To learn more about the campus standards for accessibility and captioning, please review the ICT Standards draft.

DVD to Digital Media File Conversion

If your video content is on a DVD, you will first need to convert the DVD to a digital file format before uploading it into Kaltura. If you need assistance with this process, first contact your department to see if an affiliate unit (i.e. ASSETT or ALTEC) can assist you, if not, refer to Norlin Library's Streaming Media Conversion & Upload Service.
