Opencast is a university-wide video management service that on the one hand enables the automated recording of (teaching) events in large lecture halls, on the other hand offers the storage and provision of digital instructional videos mainly in ILIAS, but also in web projects or in the OER framework. The playback of the version installed at the University of Cologne is always via HLS streaming.

Digital instructional videos

Due to the constant increase in digital instructional videos, their direct provision in ILIAS is no longer up-to-date, both for storage reasons and the way they are played as HTML5 videos. As a video management system, Opencast offers the management of the videos outside of ILIAS. Most of the management functions are directly available to you in ILIAS. The following functions are possible:

  • Upload videos
  • Record videos in the browser ('Opencast Studio' see below)
  • Take existing videos from Opencast
  • Delete video
  • Cut videos
  • Change metadata
  • Put videos on/offline
  • Allow students within a course to upload videos themselves

Further functions can be found in the user interface of the local installation of Opencast.

How to use these functions in ILIAS in general, you can read in the handout to Opencast in ILIAS or follow this link for a short description via video.

All accesses are only possible within the ILIAS course authorizations and roles.

Via the opencast object in ILIAS, you will also find a tool for creating your own videos. 'Opencast Studio' allows the creation of video content in your browser in an uncomplicated way and without the installation of additional software. It allows you to simultaneously record your screen or window of a single application (e.B. a presentation), your audio output and the image of your webcam. How you combine these possibilities is up to you. Lectures, presentations, instructions or lectures can thus be easily made accessible to students regardless of time and place. See this link for a short video on using Opencast Studio

Unfortunately, no pure audio files can be processed in the Opencast system at the moment, so the conversion into a video file is necessary. A very easily accessible option is, for example, the use of Microsoft PowerPoint without having to resort to dedicated and usually complex multimedia editing software. A quick start guide can be found at this link.
