Video platform Opencast

In order to improve the production, processing and distribution of your teaching videos, the software Opencast has been integrated into Moodle, the learning and examination platform of JKU.

Opencast is an open source product for planning, recording and publishing audiovisual learning content and was developed for the university context (

This service is currently in a test phase. If you would like to participate or have any questions, please feel free to send an email to

If you participate the test phase and want to publish a recording from HS1-8 in Moodle, please send an email to including date, time, lecture hall and link to the Moodle course. We will make the video available in the block "Opencast Videos" in your requsted Moodle course.

To upload videos to Opencast and make them available to students, please use the block "Opencast Videos" in Moodle.

The Opencast administration web client is only needed if you want to use the online video editor. Otherwise the administration via the block "Opencast Videos" in Moodle is sufficient.

  1. Open the Opencast administration web client in an up-to-date browser:
  2. Log in with your  JKU Account
 "Events" and "Series" Tab


In the "Event" tab you will find the overview of all recordings (to which you have editing rights).

  • Sort events: Click on one of the column headings (e.g. "Title" or "Date") to sort the recordings in ascending or descending order.
  • Filter events: If you click on an entry, e.g. the room "HS1", a filter will be active and only recordings of the room "HS1" will be displayed. This way you can filter by date, room and status.

In the "Series" tab you will find an overview of all series to which you have editing rights.

Series are automatically created by us when we make the block "Opencast Videos" available to you in your Moodle course. The name corresponds to the course ID number consisting of the semester and the course number (e.g. "2021W000000"). There can be a maximum of one series per Moodle course.

More information on the "Opencast Videos" block.

If the list of series or recordings is not complete, you must trigger the synchronisation of the rights. To do this, please click on Play in Moodle for an included Opencast video and log in again if necessary.

  3. Select the desired task/workflow:
    Additional actions select workflow
  • Publish
    If you have not published your recording via the video editor, this task can also publish your recording.
  • Process upon reschedule
    This task is only needed if videos fail during the first upload due to unfavourable WebRTC parameters.
  • Republish Metadata
    If you have made a change to the metadata after publishing your recording (e.g. name of the recording, contributors or date/time), this task will also update the metadata outside the backend ( (e.g. for embedded videos in Moodle or similar).
  • Retract

    This task retracts a recording that has already been published. For example, if you have uploaded an entire lecture series but do not want to publish them all at once, simply retract the recordings and publish them at a later date. Retracting and republishing also allows you to refresh the still image with the recording information at the beginning of the video if you have changed it after publishing.

  • Duplicate Event
    This function allows you to duplicate a recording.
    One reason for copying a recording could be that you want to publish two sequences from a recording individually. Be sure to change the metadata before publishing so that you do not have to reduplicate them afterwards.
    Another reason could be that you want to upload a recording into two different series. This way you don't have to upload it twice, but can select a different series in the metadata for one recording. Please do not forget to update the access rights afterwards. To do this, click on the series details (green symbol in the "Actions" column), then on the second tab "Access rights" and finally on the green button "Update access rights of individual recordings".
  • Update previews
    This task updates the thumbnails that are displayed in the video editor.
