Blackmagic Atem Mini, what is it?
The Blackmagic Atem Mini is an HDMI switcher and USB video interface. It is capable of live switching between four HDMI inputs, or rather four cameras that can output an HDMI video signal. The Atem Mini supports video signal formats up to 1080p60. It is also capable of interfacing with a computer, via a USB cable, in order to send a video signal to a computer. It uses a USB-C to USB-A cable to connect to a computer. The video signal can then be sent to remote collaborators using a variety of popular video streaming platforms such as Zoom, Skype, or OBS Studio. The Atem Mini is great for theatrical or live music performances, and also video conferencing. This unit is quickly integrates Zoom meetings, and it makes setting up your audio, an often overlooked component to video streaming, very easy. You will want to download the Blackmagic application “Atem Switchers Update” to get started.
