How is Kaltura MediaSpace intended to be used?

Kaltura MediaSpace is a service available for hosting and delivery of media files by UW-Madison faculty, staff, and students for UW-Madison-related purposes. Kaltura MediaSpace is not intended for media storage or archival purposes.

Can I upload whatever I want to Kaltura MediaSpace?

Users should comply with campus policies, including Responsible Use of Information Technology Policy and the University of Wisconsin System’s Kaltura Terms of Use Policy. UW-Madison does not routinely pre-screen, monitor, or regularly review posted content and associated data, yet reserves the right to remove, at any time, at its sole discretion, any content considered to violate these Terms of Use or the provisions of any other campus policies that may govern use of the campus networks, or that it deems in violation of a University policy or local, state, or federal law.

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. If you decide to host viral videos using YouTube, you have the option to embed those videos in Kaltura. Please see Kaltura Media Ingestion Tools for more information.

What are your recommendations for webcam recordings and screen captures?

We recommend you keep your webcam and screen recordings short (5-10 minutes) for a few reasons:

  1. Shorter recordings reduce the cognitive load on the viewer;
  2. Lapses in the viewer's attention become more frequent with longer videos;
  3. Updating your material is much easier if it is more modular (updating a 5 minute video is a lot easier than a 60 minute video); 
  4. Longer recordings tend to encounter more frequent technical issues

How much storage is available to me?

While currently there are no formal storage or bandwidth quotas in Kaltura MediaSpace, users are encouraged to be mindful of the amount of media uploaded. The cost of UW-Madison’s use of Kaltura MediaSpace is partially based on the amount of storage and number of times videos are streamed. As a best practice, please regularly review your content and remove media that is no longer needed.

What format of video should I upload to Kaltura MediaSpace?

We generally recommend that you upload MP4 video to Kaltura MediaSpace. More detailed specifications can be found in Kaltura - Recommended Video Source Formats and Specifications (UW-Madison).

How long can I keep my media on Kaltura MediaSpace?

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 Media Analytics (UW-Madison)

At this time there is no regular removal of media from Kaltura MediaSpace. However, UW System is exploring options for potentially removing media based on usage patterns or age. Active users would be notified in advance of any removal policies.

Is the original media file kept in Kaltura MediaSpace?

Source files ARE retained as part of the transcoding process, so they CAN be retrieved from Kaltura MediaSpace. Although the Kaltura MediaSpace server retains the original copy, it is recommended that the content publisher retain an original copy of their media content for archival or other purposes. For information on how to download the source file, please see Kaltura - Downloading Media (UW-Madison).

What happens to my media when I leave UW-Madison?

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. Files deleted from Kaltura MediaSpace cannot be restored.

Should I caption my video?

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. Adding captions to video is very straightforward in Kaltura MediaSpace. Instructions are located here: Kaltura - How to add a captions file to media in MediaSpace (UW-Madison) . The two UW-Madison approved vendors for captioning are 3Play and Automatic Sync. More information can be found here.

Are there recommended conventions for tagging media?

Tags are used to help find media when searching. You should make tags as meaningful and relevant to the media as possible so they will be useful in a search. And, you can add as many tags as you want. Tags can be a useful way to group your media. For instance, if you have several pieces of media for one course, it’s a good idea to tag them with the same course title or code so that they can be located together in a search.

Can I give other people access to manage my media and channels?

Yes. For more information about sharing access to channels, please see Kaltura - Sharing Access to Channels (UW-Madison). For more information about sharing access to your media, please see Kaltura - Media Collaboration - Changing Media Ownership, Adding Editors and Publishers.
