This is because ARRI's wireless control unit, the WCU-4, not only controls motors attached directly to the Mini, but with the right license, the WCU-4 can also change settings on the camera. The WCU-4 works directly with the ALEXA Mini, as well as other ALEXA Plus cameras (ALEXA Plus, ALEXA XT Plus, and ALEXA SXT), or with their UMC-4 receiver, which means you can use it for a wide variety of scenarios. In this video series, I will break down how to connect the WCU-4 with the Mini, and how to remote control the camera. Then in the second video, I give a demonstration of how to create lens mapping files to work with non-LDS or Cooke /i lenses.
