Blackmagic Studio to Atem Mini Pro

Hi All,

I have tried to find the answers here and am struggling to figure out where I am going wrong.

I have the Blackmagic studio 4k, which I have recently updated to the most recent software. I have it plugged into an SDI cable (50m) to a micro converter. The micro converter has power, and has been updated too. I have that then going into the Atem mini Pro via HDMI into camera channel 1. I can't get it to show up on the switcher at all.

I have plugged it in directly through HDMI which works fine. I have gone into the cameras settings and I thought I had set it to output as SDI (this is soemthing I think I may be doing wrong).
I am struggling to find in the manual what to do. I have tried both a [Micro Converter SDI to HDMI 12G] and a [Micro Converter Bi Directional SDI/HDMI 12g]

I have tried plugging both of the SDIs in and having only 1 SDI (the SDI Out) plugged in.

Sorry if that's not enough info and thanks for any help in advance!

Check the camera resolution - the ATEM Mini range don't accept 4K signals, and the studio camera will output 4K on SDI while down converting to HD for the HDMI output.
