I have some question about the professional streaming service i see online.
Often they have from 4 to 8 cameras so i can assume that they use video mixer with something like a control room and they send to the streaming device a "out" signal they runs out of the control room?? Am I wrong??

Are normally SDI or HDMI?? cause i've seen BNC connections that is NOT an HDMI standard plug.

If i want to use OBS studio as a "control room" i need MANY input devices, what do you suggest??
a Desktop PC with 2 or 3 HDMI card like the good old Live gamer HD?? could do the job??

OBS can handle such amunt of inputs?

Thanks
