This video shows the setup that I use when I live stream teach from my office at the university. I use Zoom, PowerPoint, and free OBS broadcasting software. The hardware included a laptop with two external monitors, Logitech BRIO camera, a ringlight, a wireless lapel microphone, and a green curtain as background. I show how to setup OBS with green screen effect so that the slides are shown behind the presenter and the opposite setup where the presentation is shown in front of the presenter.
