Kaltura - Live Streaming Events

University of Wisconsin System (UWS) institutions can use Kaltura Live to stream events to large online audiences. This guide can help campus Kaltura administrators determine if Kaltura Live is the correct streaming platform for them. This guide also discusses how to set up events in Kaltura Live.

This guide focuses on setting up live streaming through Kaltura Live. Streaming should be one part of a larger video production plan. Consult with your campus video production staff, event planning staff, and network staff before undertaking a streaming video production of a live event.

The University of Wisconsin System (UWS) has licensed Kaltura Live. This does not include the additional features in Kaltura's Live+ or Webcasting modules. 

Advantages of Kaltura Live stream:

  • Available to all UWS institutions under existing contract.

  • Privacy: Kaltura doesn’t use or sell user data.

Disadvantages of Kaltura Live stream:

  • Single source only; video mixing or switching must be done upstream through other hardware or software.

  • Streams the same bitrate (level of quality) for all users. It doesn’t scale up or down depending on user bandwidth.

  • Setup requires precise detail. See the Live Encoding Best Practices Guide for advice.
