Kaltura MediaSpace Experiences Intermittent Issues

October 2, 2020 Update: Kaltura has indicated that the ongoing issues users were experiencing with Kaltura MediaSpace and the Kaltura Canvas integration should be resolved. The Learn@UW-Madison continues to monitor these and other Learn@UW tools.


September 9, 2020 Update: Although significant improvements were made directly after the weekend, Kaltura MediaSpace and the Kaltura Canvas integration are experiencing intermittent issues again. Due to these ongoing issues, the Learn@UW-Madison team has developed a KnowledgeBase document outlining how WebEx, Zoom, Canvas and Google Drive can be used as temporary alternatives.


Kaltura MediaSpace, the university’s cloud-based video hosting platform, as well as the Kaltura Canvas integration are experiencing intermittent issues as instructors at UW-Madison and other institutions upload content for the semester. On the first day of class alone, 891 videos accounting for 190 hours were uploaded to UW-Madison’s Kaltura MediaSpace. 

The influx in uploads has led to some users experiencing issues. Kaltura has doubled capacity to start to address media processing delays, and done work to address some of the errors users were seeing. While there has been improvement in the system’s stability, the following issues are still occurring:  

  • Media is taking longer to process and become available. Videos may take 24 hours or longer to process. Kaltura is hoping this will improve through the weekend.
  • Kaltura Capture uploads may stall and not complete.
  • Lecture captures may not upload.

Learn@UW-Madison, the DoIT Academic Team that manages Kaltura Mediaspace, continues communicating with the vendor who is working on the issues as quickly as possible.

Videos are an effective way to create a sense of connectedness when teaching remotely or in a blended course. This Developing High Quality Video & Audio guide provides recommendations for creating high quality media. One important step is to break long videos into shorter cuts. Various studies have shown that limiting instructional videos to 6 minutes or less has a positive impact on student learning. Not only does this make it easier to reuse videos in the future, it also helps with load time.
