How Do You Synchronize Multiple Cameras To A Video Switcher?
• Identify your switcher as the type that needs to be timed or “genlocked” with camera inputs. AV mixers and some of the newest switchers have automatic timing. Just plug in the cameras and they work. Older professional switchers have connectors in back that are labeled “Ref In”, “S/C” and “BB” among other rows of inputs and outputs. • Identify your cameras as the type that can be timed or “genlocked”. Only pro cameras are “genlockable”. Look for a BNC connector on the camera that is labeled GEN or REF IN. Non-pro cameras will require a second piece of equipment called a “Time Base Corrector” or TBC. (See Tips). • Acquire enough BNC cables to do the job. Two, equal length BNC cables will be needed for each camera. They will need to be long enough to reach from the camera position to the switcher. If you happen to have a multipin camera cable that connects to a camera control unit (CCU), then the cables only need to reach the CCU. A bunch of shorter cables will be handy for monitors and
