OBS (Open Broadcaster Software) or OBS Studio is a software for video recording and live streaming. It is available for Windows, macOS and Linux and is particularly popular with streamers. It is an open source software that can be downloaded directly from the OBS project page.
OBS can be used to create videos for lectures that do not have to be edited or processed afterwards. During the recording, you can switch between different scenes that were already created before the recording.
Our Anleitung (PDF) with recommended settings as well as tips and tricks for OBS gives you an overview of how a very simple setting for a video recording can look like. Integrated into moodle, you can, for example, present frequently asked questions or more complex topics with short videos.
For those interested, we would like to recommend the OBS Studio Complete Course, which provides various instructions on possible applications.
