ARRI Camera Stabilizer System: TRINITY

ARRI Camera Stabilizer System: TRINITY

With gimbal technology and usage accelerating fast, the symbiosis between cameras and stabilizers is becoming increasingly sophisticated, which is why ARRI has incorporated the new CSS (Camera Stabilizer System) product group into its camera systems division. The flagship of the range is ARRI TRINITY, incorporating the MAXIMA gimbal, though behind this unique 5-axis hybrid stabilizer is a complete system that covers varied requirements across the film and TV industry.

TRINITY is the first hybrid camera stabilizer that combines classic mechanical stabilization with advanced active electronic stabilization, provided via 32 bit ARM-based gimbal technology. This combination results in five axes of control and enables uniquely fluid, wide-ranging and precisely controlled movements for unrestricted shot-making and total creative freedom. 

New angles for the operator and new storytelling options for the director and DP are opened up by TRINITY. By inverting the post the camera can be moved from low mode to high mode during a shot; using the joystick-controlled, fully-stabilized tilt axis to look up or down during this motion is also possible, so a low angle can smoothly transition into an over-the-shoulder shot. By holding the post at 45 degrees and twisting it left or right, the camera can even look around corners, whether in low or high mode. Additional stabilization in the roll axis permits the use of telephoto lenses.

All of these extraordinary new shots, angles and movements are possible when TRINITY is used in its fully stabilized mode. For situations when a more classical style of operating is required, TRINITY can be put into a locked mode, whereby the tilt axis is connected directly to the post in the traditional manner.

TRINITY is available as a complete 5-axis rig or as a 2-axis head upgrade to existing mechanical stabilizers. While it works especially well in a compact configuration with the ALEXA Mini, TRINITY's 30 kg maximum payload and height adjustability mean that larger cameras and heavy lenses can also be supported. Full-size digital cameras such as ALEXA SXT are easily accommodated, as are film cameras such as the ARRIFLEX 235 and 416.

The MAXIMA gimbal is a crucial component of TRINITY, though it is also available separately as the MX30 -- a 3-axis electronically stabilized gimbal, suitable for a wide range of users. The slick, lightweight design, with perfect center of gravity, provides a level of freedom that has not previously been possible. With MAXIMA, the creativity of filmmakers need not be stifled by camera length or weight limitations. 

At the center of the unique MAXIMA design is an extremely durable ball bearing roll cage, as well as specially designed brushless motors. Optimized bearings and high torque ensure that there is always enough power in reserve, no matter how demanding the application. Carefully selected components enable seamless, reliable operation and impressive heat resistance. 

Direct and intuitive handling of this high-capacity gimbal is managed by a 32 bit multiprocessor; additional slave RISC processor support means multi-sensor data is processed without losses. The maximum angular deviation is just 0.05 degrees. In addition to a variety of preconfigured profiles, customized profiles can also be added.

The 1.5" OLED screen allows users to keep tabs on the operating mode and battery status, and to quickly toggle between different profiles. 'On the fly' configuration of software setups and rapid changes between the five customized camera settings can be done via the smart GUI, while bigger setup alterations and software updates can be implemented via USB.

Changes of angle are achieved with a highly sensitive and ultra-precise joystick mounted at the outer frame of MAXIMA, close to the handles. An optional bidirectional 2.4 GHz wireless remote control is also available, allowing tilt, pan and roll movements. The intelligent software and precise hardware enable vertical swivels of up to 90 degrees.
