This document is intended to provide foundational information about UW-Madison Kaltura MediaSpace, including some guidelines and recommended best practices for usage.
These recommendations are more important while Kaltura MediaSpace is seeing unprecedented usage during the COVID-19 situation:
Kaltura MediaSpace is a service to stream media files from UW-Madison faculty, staff, and students for UW-Madison-related purposes. Kaltura is not meant to be a permanent storage repository where media lives forever. We recommend you keep a backup copy of your media files outside Kaltura and delete media that is no longer needed or used. In the future it is possible media may be archived or deleted if a media item has not received any plays within two years.
Chrome and Firefox on Windows or macOS platforms work best for viewing embedded Kaltura MediaSpace videos in Canvas.
The speed required to view Kaltura MediaSpace videos varies based on the size of the video uploaded. At the high end, users will need up to 4.2 Mbps download speed to view the largest, highest quality videos uploaded to Kaltura MediaSpace. Many uploaded videos don't require that top-end speed. You can also manually select a lower quality version of a video by clicking Play, then Pause, and finally the gear icon to select a lower quality version. More information is available in the KnowledgeBase document Requirements to view Kaltura MediaSpace videos.
Kaltura MediaSpace doesn't have a file size limit. However, the larger the file, the longer it takes to upload and process. We recommend that you try to keep your file sizes under 2 GB as some browsers may have trouble uploading larger files. We generally recommend that you upload MP4 video to Kaltura MediaSpace. More detailed specifications can be found in Kaltura MediaSpace - Recommended video source formats and specifications (UW-Madison).
Currently there is no quota or limit to how much media you can upload to Kaltura MediaSpace. However Kaltura MediaSpace is not meant to be a permanent storage repository. We do recommend you keep copies of your media files so you'll have your own copy should you leave UW-Madison. In the future it is also possible that we will need to implement a policy to delete media that has not received any plays within two years.
After your file is uploaded, Kaltura MediaSpace will take additional time to initially display your video in your "My Media" area. When it does appear in My Media an icon indicating it is still processing will display until it is done processing. The amount of time it takes Kaltura MediaSpace to process a file is dependent on its complexity, file size, and duration.
Generally it takes about 2-3 times the video's duration for Kaltura MediaSpace to display an initial lower quality version of your video. For example a 15 minute video will usually take about 30-45 minutes to initially process. The other higher quality versions will take longer to process. When Kaltura MediaSpace is being heavily used, processing times will lengthen and could take up to 24 hours. If your video takes longer than 24 hours to process, please call the DoIT Help Desk. More detailed information is available in Kaltura's document involving transcoding times and quality of service.
Yes, you can embed any videos you have in Kaltura in Canvas anytime you use the Rich Content Editor, such as in Discussions, or if your instructor gives you permission in Pages, Quizzes and Assignments. You can also access your personal Kaltura MediaSpace media by using the "Kaltura My Media" feature available from your Canvas account profile.
"Kaltura My Media" can be enabled by an instructor in Canvas course navigation or accessed by clicking your user profile and selecting it. Each instructor or student will see their own media here - not the course's media. For more information see Canvas - Upload, access, and share video in Canvas with Kaltura My Media . "Kaltura Media" (soon to be renamed "Kaltura Gallery" is a media gallery of shared media with the course participants. For more information see Kaltura - Using "Kaltura Gallery" course media galleries and analytics in Canvas .
While Kaltura MediaSpace content can be delivered to audiences outside UW-Madison, the service is not intended for viral videos that receive tens of thousands of hits. Please consider using an alternate video platform like YouTube or Vimeo if you want content to have a wide public audience. If a media item has “gone viral”, an alternative delivery platform may need to be considered.
We recommend you keep your webcam and screen recordings short (5-10 minutes) for a few reasons:
Kaltura MediaSpace is not a repository for the permanent storage or archival of digital media. Currently, it is the responsibility of each user to keep a copy of their media, monitor the active usage of their media, and remove media that is no longer being actively viewed or used.
For more information on how to monitor the active usage of your media please see Kaltura - MediaSpace analytics (UW-Madison)
As of Spring 2020 there is no regular removal of media from Kaltura MediaSpace. However, we are exploring options for potentially removing media based on usage patterns or age. Users would be notified in advance of any removal policies. We recommend you keep backup copies of your media files outside Kaltura and delete media that is no longer needed or used. In the future it is possible old media may be archived or deleted after a period of two years of inactivity.
If you are leaving the university, please delete media that is no longer needed. If you would like to transfer ownership of your media to another user, please follow this tutorial: Kaltura - Media Collaboration: Changing media ownership, adding editors and publishers. Users can also submit a bulk ownership transfer request by following the instructions in Kaltura - Requesting changes including ownership, download, co-editor/co-publisher/co-viewer and restoring deleted media (UW-Madison) .
UW-Madison’s Web Accessibility Policy specifies that every non-text element posted on the web—including audio and video files—must have a text equivalent. Users can add captions by following Kaltura - How to add a captions file to media in MediaSpace (UW-Madison) . For more information on captions see Captioning transcripts, and audio descriptions - Getting Started (UW-Madison) .f
