Mac Mini for 4K streaming
I am considering getting a Mac Mini for 4K streaming--although as of right now, I may decide to wait until the next round of the M chip version. I've never owned a Mac before, and am totally unfamiliar with the type of ports on the Mini.
What would be the best option for getting 3 or 4 4K streams in to a Mini? I have one 4K USB capture device, but would prefer something like the Atem Mini for multiple devices, but I'm not finding anything like that for 4K capture. All my cameras are HDMI.
There current M1 MacMini has 2 Thunderbolt 3 ports (USB-C USB3.1) and 2 USB A ports. Thunderbolt devices. I'm not sure if there's a good way to get 3 or 4 4K sources into it. It's possible if you can find a PCIe card that supports 4K on each input and then a PCIe to Thunderbolt case, that may work. Magewell makes HDMI 4K cards. We haven't tested this workflow.
It's possible the processing and bandwidth resources for 4K HDMI are difficult especially when you add heat dispersion.
