The ATEM Mini Pro retains the same rear-panel setup on which four HDMI inputs are available on the rear of the chassis and they input up to 1080p HD video. There is also an HDMI output for a projector or multiview monitoring, a USB Type-C output as for recording HD video to a computer, and an RJ45 10/100/1000 Ethernet port for direct live streaming as well as system management, remote control, and upgrades. You can adjust frame rate depending on the quality of your stream, and there is no need for additional streaming software because the Pro includes a built-in hardware encoder.
