Best setup for 2 key&fill + Ref In

I am wondering what is the best card(s) to get 2 key and kill sources (two different graphics simultaneously)out of a CasparCG system and into the ATEM 4M/E while also having reference in.

In 4k

To be honest I would like to know as well

Because currently I have a decklink quad that I am trying to set up on caspercg
I can’t see any of the outputs on my atem

I have been trying for the last 3 days of trial and error. There has been lots of cursing and swearing

I have been watching all the YouTube and reading the caspercg forums but no way in hell would it work

So if anyone has solutions. I would greatly appreciated

A quad or Quad 2. Be sure you have setup the card first trough Desktop Video application

Also first put a monitor on it to check if you have SDI output and in what resolution and framerate.. As you need to match the res and framerate of the Atem or it wont show..

Also check with Caspar documentation what the propper numbering of the ports is.. It could be 1,5,2,6,3,7,4,8,ref

so even the DeckLink 4K Extreme 12G can only do one 4k out for key&fill? can i use on of the sdi ins for ref. in?

Decklink 4K Extreme will do 1 in and 1 out.. The Extreme part only points to all other input posibilities.. (Analog, Fiber, Hdmi, Etc..) The Genlock / Ref connector is in the fan out cable on that one. That is the High Density connecot above the SDI connectors..
