Filter Reading System for ARRI LMB 4×5 and 25


The Filter Reading System (FRS) upgrade for the ARRI LMB replaces the filter section of the matte box with a new module that includes an RFID antenna, an upgraded brake system,and composite trays. The system reads inserted filters using RFID tags that are adhered to the edge of the glass, and displays the data on wireless e-ink displays, or “CineTags.”

Using the RFID sticker tags, the FRS module detects the type and position of each inserted filter and displays the information so that the camera crew can easily keep track of what is in the matte box.

The tags are easily programmable using a phone app. Each filter tag can be programmed to include a custom display name, as well as different background colors and display modes.
All of the filter programming can be done either at the rental house or in prep, leaving the camera crew free to focus on more important things during a shoot.
The FRS doesn’t send data to the camera quite yet, but each connected CineTag does log every filter change to a CSV file either using timecode or real time.
