ATEM Mini features 4 HDMI inputs and has an intuitive, easy to use design. The 4 high quality HDMI inputs can be used for live switching cameras, computers or even game consoles. A built-in DVE provides picture in picture effects, broadcast quality transitions, upstream keyers for removing blue and green screen background, a downstream keyer for superimposing custom graphics, audio inputs, an audio mixer, and more. ATEM Mini also has a USB output that works like a webcam, so you can connect to most any video software, including ProPresenter 7. There's also HDMI video out for projectors.
