Having trouble with the Decklink 8k Pro, and Black Magic products are so incredibly unintuitive I can't tell if I have bad hardware or if I'm just using it wrong.

The goal is to have 4 separate inputs. Our multicam setup works great with the Decklink Duo 2. But with the 8k Pro, no dice. At most I can only ever get one input to work at a time. Whichever one I add to vMix first. But even with just one input, sometimes it will just randomly stop working and instead of a video feed I'll get loud static on the audio channel.

The only bit of guidance I've found is to use this process to set up the decklink: https://www.vmix.com/kno...pro-in-4-channel-4k-mode

Am I doing something wrong here? Or do I just have a bad card?
