So I'm running this event at a venue, and they don't have a usable video system in the arena. I am the director, and would like to record it using at least four different video angles, (event will take place on a central stage), and then play them back later through a video mixing device, and record it then. I guess what I'm saying is I want to record each video feed separately. I do have access to a video mixer/desktop production device, but how would I go about recording all this video? I don't have any cameras, cables, or any type of hard disk recorders. Any advice?
