ARRI UMC-4 Lens data: The Arri UMC-4 Controller incorporates the LDS lens data file and generates accurate lens data for any purpose. The lens data is used for the assignment of lenses to the previously marked focus rings and the visualization of the depth of field in the WCU-4 manual unit. It allows focus tracking by configuring the motor to continuously track a subject by using a Cinetape UMD-1 meter. For VFX tasks, the UMC-4 records lens data with timecode, which helps to match exactly the virtual lens with which it was shot.

ARRI UMC-4 Timecode

The UMC-4 supports an internal and external timecode that is recorded with lens data and frame accuracy on SD card, making the lens data able to be used for post-production. The internal time code clock can be synchronized through an external device, but they can also issue LTC time code
