What is Kaltura?

Kaltura is a hosting service that we have contracted with to provide rich media streaming services. It allows for uploading, editing and managing rich media content for campus colleges, schools, departments and groups. It allows for integration with the campus online learning environment (Desire2Learn) and with campus websites. It allows for media such as video, audio, photographs to be stored and presented in a variety of way to benefit faculty, students, campus affiliates and external viewers.

What is the maximum file size upload via Kaltura?

A maximum approaching 2 GB worth of data may be uploaded into Kaltura at a given time. If you get any error upon uploading, please check the file size.  If the file is too large there are free programs such as iMovie (for Mac) and Live Movie Maker (for Windows) that will edit files down in size.  If further assistance is needed, a media preparation service is offered (for a fee) at the Norlin Library e-reserves.

What is the maximum file size upload?

There are no file size limits for files uploaded to D2L; however, the ability to upload large files is influenced by your Internet connection and web browser. If a file is too large, the browser may time out or stop the upload.

Does Zoom integrate with Desire2Learn?

Zoom does not include a “credential passing” Learning Tools Interoperability (LTI) integration with Desire2Learn. However, D2L’s “content” link posting can be used to share a link to a Zoom meeting. For more information on adding a Zoom link in D2L, please visit the D2L - Add a Zoom Web Conference Link tutorial.

No. Grades and other sensitive information should be password protected and sent via a more secure route than an email message. OIT recommends using the Large File Transfer service to more securely send grade files.

What are Intelligent Agents and why should I use them?

The Intelligent Agents tool allows Instructors to setup automatic notifications to be sent to themselves, advisors, and students when specified course performance criteria are met. It can be a great way to both recognize student achievement (e.g., a high score on a quiz) and warn of potential problems (e.g., lack of online activity or poor performance on an exam).  Setting up intelligent agents can help instructors monitor each student’s performance and provide students with feedback without a lot of additional follow up by the instructor.

Visit OIT's Creating an Intelligent Agent tutorial for step-by-step instructions.
