OBS tutorial 

This is an introductory tutorial of OBS (open broadcast software). OBS allows you to set 'scenes', effectively giving you the ability to organise many inputs into your stream/recording resulting in personalised screens that are flexible and instantly switchable.
Integrating OBS into your recording process will give you a form of stage management and blocking capability for your online content creation and can also be used to record a stream without being 'live' on a platform.
The video concludes by showing a basic example of how, alongside other software, you can even use it to integrate a virtual stage into your recording.
