Hey,
The specs say the card has direct show, which i think is a good sign it will work with resolume, but i as long as nobody tested it, could possibly not work. Is latenzy an issue in your setup ?
I have good experince with the blackmagic stuff, decklink quad (v1) would have 4 SDI inputs, which can be used simultainiously. You would have to convert every hdmi signal to sdi, which would cost abit.
I worked with 4x decklink recorder(lowcost pcie hdmi input) so with the right motherboard a 5x setup is possible.
I would recommend one decklink quad and one decklink recorder, or two decklink duo and one decklink recorder.
Hope that helps
PS: if you can get your hands on a quad v2, you have up to 8 inputs for the same price as the v1.
I'm not sure if the PCIe will make a difference but my BM Intensity Pro cards (R.I.P.) had much lower latency than the Magewell USB 3 capture card. I assume this is because Resolume is designed to work directly with BM devices
Just to pitch in I use the 4 HDMI PCIe card first gen, make sure your motherboard has PCIe Lanes, i6700 are no good. I use a 5930 or 5960 to get the 40 PCIe lanes. Also the motherboard must be good. If you can find one, get one with a PCIe data watcher, so you see where the bottleneck would be.
