Recently I worked on a multi camera live stream for a school event. The plan was in basis quite simple: we would have four cameras set up across a hall connected to an ATEM Extreme ISO so that we can monitor and live output to a Youtube stream. We used SDI Cables connected via SDI to HDMI Converters to connect to the ATEM. All the cameras we used were BlackMagic Pocket Cinema Cameras, Our A cam we used had an 18-35 lens on which captured a wide shot of the event. For a B camera we used a 70-200 with a person focus pulling and controlling it, Our C camera was connected to an electronic slider which we keyframed to move slowly back and fourth. Our final camera was using a 50-100 which captured a slightly wider tight shot which was generally stationary setup by out ATEM.
