Easy to Learn and Fast to Learn: There's never been a switcher that’s easier to use, as you simply press any of the input buttons labeled 1 to 4 on the front panel to cut between video sources. You can choose between cut or effects transitions by selecting the cut or auto buttons. Unlike cut, the auto button tells ATEM Mini to use a video effect when switching inputs

Connect up to 4 Independent Cameras: With 4 independent HDMI inputs, you can connect up to 4 high quality video cameras. Video cameras with HDMI outputs are dramatically better quality than simple webcams as they use higher quality lenses and have better low light sensitivity

Outputs to HDMI Video and USB Webcam: To ensure maximum compatibility, ATEM Mini features a USB connection that operates as a simple webcam source.
