ARRI UMC-4 (Universal Motor Controller) is a sophisticated, three-channel motor controller designed to bridge the gap between various cameras and ARRI’s electronic control system (ECS). It provides complete remote control of focus, iris, and zoom on nearly any camera and lens combination.
Universal Compatibility: Works with ARRI, Sony, Canon, RED, and Panavision cameras, allowing for a standardized workflow across different platforms.
Three-Channel Control: Supports up to three lens motors (Focus, Iris, and Zoom) simultaneously.
LDS Integration: Equipped with Lens Data System (LDS) technology, which transmits lens metadata (focal length, T-stop, focus distance) to the viewfinder or recording media.
Wireless Reliability: Utilizes the white-coded radio module for high-speed, long-range wireless communication with ARRI hand units like the WCU-4 or Hi-5.
Internal Recording: Features an SD card slot for logging lens metadata, which is invaluable for high-end VFX and post-production tracking.
Timecode Support: Built-in timecode clock ensures frame-accurate synchronization between lens data and camera footage.
