The ATEM Mini Pro Iso model has a built in hardware streaming engine for live streaming via its built in Ethernet connection. That means you can live stream to YouTube, Facebook and Twitch in better quality, without dropped frames and with much simpler settings. Just select the streaming service and enter the streaming key! There are palettes in ATEM Software Control for streaming setup and status, plus streaming status is also displayed in the multiview. Streaming status is easy to understand as the data rate indicator shows internet speed required for the video format you're using. If you're technically minded, you can even hack the detailed streaming profiles in the XML preference file and load new services.
It also offers a recording function, where you can record all 4 streams of video, along with your mixed edit onto an external USB-C drive, AND it saves it all as a DaVinci file for editing later.
