For the 8K Pro card there might be an option to run 4x 12G to the card if they are in sync with eachother..
But this needs to be tested.. And i don't own the card yet..
Kind of the way some other brand has done this with there recording monitors..
**Trying hard to not name the brand here..
So when all sources are the same framerate and resolution.. And run in genlock with eachother.. you might be able to pull off something like this.. That doesn't help anyone that needs to capture 4 seperate 4K streams..
And likely will never be able to do this with this card due too possible missing framebuffers on each input.. Which prevents the card running unsynced feeds..
But for some people running an ISO recording from 4 Ursas that are synced up.. Or 4 outputs out of an Atem 4ME Broadcast switcher were all PGM and AUX channels run in sync..
It could be a "solution"...
This would be similair to Quad Link Square Division setup used in 12G single link..
But it might be very well not run if the 8K Pro card does a good check on Payload ID's.. As for Square Division every Square has a number ID in the payload for indentification.
While 4 seperate streams don't have that... So might or not might work..
I can and will test that if i can get my hands on a test card / demo card..
