[joseph wilkins] “So the ex1 and c100 would be best?”
Yes as HDMI and/or SDI gives you the best HD quality source.
MXO2 would work for one camera.
You could get Blackmagic Ultrastudio MiniRecorder for the other.
I’m not sure if the two drivers will play well together otherwise you can use two MiniRecorders. They’re only about $140 each. Telestream will be testing them but they do work.
I have both the MiniRecorder and MXO2. The MXO2 needs the Thunderbolt adaptor… which does cost more than a MiniRecorder.
Also not tested by Telestream but Magewell has a driverless HDMI or SDI to USB3 device which I’ve seen running on Mac with Wirecast.
