FoMaSystems would like to first extend a heartfelt thank you to all operators who provided feedback and helped test the new software. Your insights have been invaluable in shaping the Trinity 2 Software Update 4.0 (SUP 4.0).
By carefully analyzing this feedback, we gained a deeper understanding of how operators use the Trinity 2 in real-world scenarios. This helped us add preconfigured stabilizer modes, calibration tools, safety features, and enhanced connectivity options for professional cinematographers.
The software will be officially released by ARRI today, bringing a host of new features and performance enhancements designed to make on-set operation smoother, safer, and more versatile.
Read on to find out more about the key improvements and new capabilities in Trinity 2 SUP 4.0.
Trinity 2: The Hybrid Stabilizer Redefining Creative Camera Movement
The Trinity 2 is widely recognized as a groundbreaking camera stabilizer that pushes creative camera movement to new heights. The first of its kind to merge classic mechanical with advanced electronic stabilization, enabling seemingly impossible camera moves.
At its core, Trinity 2 is a hybrid system that elegantly combines a tried‑and‑true mechanical stabilization base with a digitally controlled gimbal head. This fusion unlocks five axes of motion and enables uniquely fluid, wide‑ranging camera movements that were previously difficult or impossible to achieve with traditional body‑mounted rigs alone.
This hybrid approach delivers features like 360° continuous roll, extended tilt range, and highly responsive positional control, allowing cinematographers to execute dynamic shots with consistency and precision, from sweeping cinematic takes to challenging run‑and‑gun scenarios.
A key strength of the Trinity 2 system is its modular design. Around 80 % of its components are shared with the Artemis 2 mechanical stabilizer, enabling operators to reconfigure rigs or upgrade without duplicating gear. This modularity enhances workflow flexibility across feature films, commercials, episodic TV, and high‑end documentaries, making it a versatile choice for professional productions of all kinds. The symmetric design of the head equalizes overall weight distribution, preventing surprises during high-speed moves, and giving operators full confidence even in dynamic, fast-paced shots.
Oscar Recognition: Foma Systems Germany at the Forefront of Stabilization Innovation
At the 2025 Academy Scientific and Engineering Awards, the Trinity 2 stabilization system received one of the film industry’s most prestigious honors. The Academy of Motion Picture Arts and Sciences awarded Curt O. Schaller for the concept, design, and development of the Trinity 2 system and Dr. Roman Foltyn — Co‑Managing Director and Chief Engineer at FoMa Systems Germany — for the software and hardware design of its motorized stabilized head.
This innovation enables filmmakers to execute camera movements and transitions that were previously impossible, providing unparalleled creative freedom on set. The award highlights FoMa Systems leadership in pushing the boundaries of cinematography technology and underscores the significant impact of our engineering expertise on modern filmmaking.

Five New Trinity Modes for Flexible Operation
One of the standout features in Trinity 2 SUP 4.0 is the introduction of five distinct Trinity modes, allowing operators to switch behavior on the fly to match the shooting scenario:
- Trinity Mode – Optimized for tight spaces, enabling nearly 0-degree look-around capabilities.
- Artemis Mode – Locks tilt motors while stabilizing the roll axis. Perfect for over-shoulder shots and steep angles.
- Top Down Mode – Maintains camera position with roll stabilization for effortless top-down shots and line-following sequences.
- Side 1 Mode – Ideal for one-axis stabilization. Tilt motor can be switched off, allowing high-speed sideways operation.
- Side 2 Mode – Alternative low-reactivity mode for specialized side operations.
Switching between these modes can be done either via Mastergrip or directly on the RCP interface, giving operators maximum flexibility.
Enhanced Calibration and Roll Control
Trinity 2 SUP 4.0 introduces Roll Scale Calibration, allowing for higher precision roll movements in just a few seconds. To perform this calibration, make sure the Trinity 2 is docked in the docking bracket and that tilt and roll motors are powered on.
Operators can access the calibration via: Menu → Head Calibration → Roll Scale Calibration
This new calibration ensures smoother automated roll movements and more accurate stabilization, especially for complex shots.
Safety Upgrade
We added a critical safety feature: in case of obstruction during a roll movement, the system will now shut down automatically to prevent damage to equipment.
Battery Upgrade
Battery management has also been improved, allowing for longer, uninterrupted shooting sessions on set.
Zoom Sync for Live Broadcasts and Long Lenses
Trinity 2 SUP 4.0 introduces Zoom Sync, enabling Trinity 2 to communicate directly with your lens via LBUS. This is especially useful for live broadcasts or long-eng lenses where smooth zoom adjustments are critical.
The Zoom Sync function is used to automatically adjust the pan and tilt speed to the current zoom factor. When zooming in, the speed is reduced; when zooming out, it is increased accordingly. This ensures that the operator always maintains a consistent feel for framing.
Operators can set the zoom-out speed and activate Zoom Sync via: FIZ Setup → Zoom Sync → Activate
Motor Off Function for Easier Setup
You can now turn off the motors, allowing one person to add batteries or attach accessories while the operator makes settings in the menu. Once the setup is complete, the motors can be switched back on immediately.
ARRI TRINITY 2 Pan Axis Module
With a Pan Axis Module attached, the Trinity 2 camera stabilizer converts into a compact and powerful three-axis stabilized remote head, allowing Trinity 2 operators to expand the skills and chargeable services they can offer on set. By augmenting the powerful tilt and roll motors of the Trinity 2 head with a similarly powerful pan axis, the new module permits Trinity 2 to be used in situations that would normally be reserved for standalone remote heads or three-axis gimbals.
The Trinity 2 Pan Axis allows Pan rotations up to 720°, in addition to multiple roll rotations and 170° of tilt range. Weighing only 3.5 kg / 7.7 lb., the compact Pan Axis Module turns Trinity 2 into a three-axis stabilized head that is smaller than most others, making it a great solution for space-constrained setups such as inside a car or mounted to a motorcycle.
The modular pan axis design has the same shape as the Trinity 2 head, enabling easy mounting. Switching between body-mounted operation of the stabilizer and hard-mounted remote head mode with the Pan Axis Module is simple and can be achieved on set in under five minutes, which allows for spontaneous creative decisions without affecting the shooting schedule. Camera builds can be left in the Trinity 2 head when making these changeovers, so no time needs to be spent rebalancing the rig.
When used as a three-axis remote head, the Trinity 2 has a formidable 25 kg / 55 lb. payload capacity. Camera and lens combinations that are physically long are easily accommodated due to the concentric ring design, allowing for simple builds, often without counterweights. All features of the Trinity 2 head, such as flexible connectivity, Camera Stabilizer System (CSS) accessory compatibility, mounting points, and tilt lock are retained.
Pan Axis Module Software Improvements
The Off Center Indicator lets operators quickly identify balance issues by observing the current and position indicators in the PID settings menu.
Additionally, Manual Drift Correction allows operators to correct drift in real-time, maintaining smooth, precise camera motion throughout the shot.
Why SUP 4.0 Is a Gamechanger
The Trinity 2 4.0 software update is a major step forward for on-set flexibility, safety, and precision. From five new operating modes to enhanced calibration, Zoom Sync, and pan-axis remote control, FoMaSystems continues to refine the Trinity for professional cinematography. Whether you’re shooting tight indoor spaces, live broadcasts, or crane shots, Trinity 2 SUP 4.0 equips you with the tools to elevate your camera work to the next level.
