The RMC-185 controller makes it easier to use the KMU-100. The integrated joystick allows you to easily pan and zoom anywhere on the 4K signal to select up to four user defined shots per 4K camera. An additional 4K camera could be connected to the KMU-100 to allow up to eight defined outputs from two 4K signals.
You can set up these shots in advance and save them as presets on the RMC-185, or you can do it in real-time. These eight virtual camera signals (up to 1080p) could be connected to any HD-SDI switcher, giving the illusion of a multi camera production when in reality, you only have two 4K cameras.
