Key / Fill option on ATEM Broadcast package

How is the Playout Key/Fill option implemented not the Broadcast version? I am looking to have mimoLive send separate Key/Fill signals from a laptop to my ATEM. I assume we would have to use a BMD Ultrastudio 4k (or maybe 2 UltraStudio Mini Monitors) to get the separate Key and Fill signals to the switcher?

@“John Mortensen” Thank you for your interest in mimoLive.

You need a Blackmagic device with at least 2 SDI outputs. They have to be in the same device so that the signal is synchronized. Two Mini Montors won’t work.

More Info and a list of supported devices:

The key/fill playout via SDI requires a Commercial or Broadcast license.
