I have 3 cameras and 1 atem mini pro. Can you send 3 cameras live on ue4?
I can’t remember for sure before, but I did a test with 3 live cam using a BMD DECKLINK 8K product. I just tested the resolution at 1920x1080 and putting 3 in seems to overload the computer and sometimes 1 out of 3 freezes. And since all of the bmd in-out boards were sdi, all cameras at the time were only HDMI output, so I remember using a converter. It’s been a while, so I can’t remember, but I hope this helps.
