I am looking into using Qlab for live cameras for an upcoming show. I know that Qlab can handle video, audio and MIDI cues (I have used it for that before), but I have never worked with live cameras. For this show, we will need 3 cameras. They will be inputted via Firewire, however I would like to know if I will need a separate Firewire cards for each camera, or if they will all work on one Firewire card with multiple inputs (I will be using a Mac Pro for this). I know some programs (such as Wirecast) require each camera to have its own Firewire card. If anyone knows the answer to this, it would help a lot. Thanks!
