For instructors and students: Access to heiCAST via the Moodle platform
Instructors and students can share videos via Moodle. In the background, heiCAST processes and hosts the video and publishes it to Moodle for playback. The steps needed to do this can be done via Moodle. Separate access to heiCAST is not necessary.

How do I record videos for teaching?

There are many different tools for recording videos for teaching that can then be shared via Moodle (and therefore via heiCAST). These are some of the available options:

  • Opencast Studio (integrated in heiCAST, browser-based)
  • Camtasia (available at a reduced price through the URZ)
  • PowerPoint presentation exported as a video file
  • OBS Studio (cost-free Open Source software, Tool for advanced users)
The Moodle video player isn't loading. What do I do?

Try using another browser. We recommend the latest version of Mozilla Firefox.

Deactivate your Javascript blocker if you have one.

My video disappeared after uploading. Why did this happen?

Make sure that the video resolution can be divided by 2.


1280x996 = OK

1280x995 = Doesn't work
