Open broadcaster is a powerful piece of software for doing streaming and screen recording. I can now do quite complex live screen recordings and UI demonstrations quickly. I now use the software every couple of weeks. I can easily integrate different video sources and automatically switch between different 'scenes' by browsing around my computer. The recordings are output to the video folder and then can easily be dropped in powerpoints.

I really like the fact that Open Broadcaster Software has the best full screen recording and multiple cameras that can be added.

OBS Studio is one of the most complete and customizable streaming softwares out there. It helps me set up my streaming settings and scenes in the blink of an eye. While it may not have that many integrations with streaming platforms directly, like showing new followers, sub numbers etc., it's really easy to use some third-party softwares like StreamElements to make it possible.
