ARRI UMC-4 3-Ch Motor Controller

3 Axis Lens Control The Universal Motor Controller UMC-4 is an advanced 3-axis motor controller. Up to three different hand units can connect to the UMC-4 at the same time, controlling focus, iris and zoom on any camera. The intuitive user interface helps to quickly setup the system and makes it easy to use. The high-quality outdoor antenna offers improved durability and reliable radio connectivity. Lens Data The UMC-4 incorporates the LDS Lens Data Archive and generates frame-accurate lens data with any lens. Lens data is used for lens mapping to pre-marked focus rings and depth-of-field display on the WCU-4 hand unit. It also enables focus tracking – setting the focus motor to continuously follow a subject by using an ultrasonic distance measurer. For VFX tasks in post, the UMC-4 records lens data with timecode, helping match the virtual lens to the recorded image. Timecode The UMC-4 supports internal and external timecode that is recorded with frame-accurate lens data onto SD card, making the lens data usable for postproduction. The internal timecode clock can be jam-synced from external devices, but can output LTC timecode as well.
