Rent Arri Universal Motor Controller UMC-4 in New York City.
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.
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.
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.
The UMC-4 includes multiple interfaces for maximum flexibility on set. Two serial interfaces connect peripheral equipment such as ARRI’s UDM-1 distance measure or motion control systems. Optional connector modules interface directly with focus and zoom demands from Fujifilm and Canon. An Ethernet connector integrates the UMC-4 with standard IT equipment, allowing Ethernet-based system control and remote access to the lens data files on SD card.
