ARRI Trinity 2 SUP 4.0 Adds New Modes and Performance Upgrades

ARRI has released Software Update Package (SUP) 4.0 for its high-end TRINITY 2 camera stabilizer and the companion TRINITY 2 Pan Axis Module, delivering a suite of new user modes, performance refinements, and usability enhancements for demanding production environments.

Why This Update Matters

The TRINITY 2 system is ARRI’s flagship hybrid camera stabilizer, blending mechanical precision with electronic control to enable cinematographers to achieve fluid, complex camera moves with reliability and responsiveness. The new SUP 4.0 builds on this foundation by giving operators more control in challenging shooting scenarios while improving everyday operational efficiency.

Key Features in SUP 4.0

The update includes several practical and performance-oriented improvements:

Five New User Modes: Tailored settings designed for specific shooting conditions — including a mode that enables panning even when the TRINITY 2 post is nearly horizontal — expand the system’s versatility directly on set.
Zoom Sync: A mode that matches the pan and tilt motion speed to the camera’s focal length, making lens-driven adjustments feel more cohesive and natural during dynamic moves.
PID Auto Tune Method: This new control algorithm simplifies the process of tuning stabilization performance, helping operators adapt more quickly to varying setups.
Motor Control Enhancements: A dedicated Motor ON/OFF switch available via the PID menu lets users manage power efficiently.
Usability Upgrades: Improvements include faster start-up times, a screen lock feature for in-field protection, an enhanced Drop mode, and more stable pairing with the ARRI RF-2400 radio system.

Each of these refinements aims to streamline workflow on set and give stabilizer operators greater control without adding complexity during high-pressure shoots.

Performance and Compatibility

SUP 4.0 is designed to work seamlessly with both the TRINITY 2 head and the Pan Axis Module, ensuring that the entire system benefits from smoother calibration, responsive behavior, and communication reliability. Operators planning to install the update should also note pairing adjustments — for example, the RF-2400 radio may need to be re-paired after applying the firmware.

ARRI recommends keeping stabilizer and related control panels up to date to get the best performance and compatibility across devices. While additional firmware packages are available for other components in ARRI’s lineup, updating to the latest SUP is essential for maintaining peak TRINITY 2 performance.

What This Means for Cinematographers

For productions that rely on agile camera movement — such as narrative film, commercials, and high-end event shooting — the SUP 4.0 upgrades offer practical gains:

More customizable handling through dedicated user modes
Increased motion fidelity with features like Zoom Sync
Better on-set usability thanks to faster boot times and interface improvements

These enhancements help ensure operators can focus on creative framing and movement rather than technical setup, reducing turnaround times between shots and improving overall shooting efficiency.

How to Access the Update

ARRI’s official technical service page lists the SUP 4.0 download and release notes, and installation instructions are typically included in the package or accompanying documentation. Crews should follow ARRI’s recommended procedures to update equipment safely and ensure compatibility across all connected systems.

The release of SUP 4.0 underscores ARRI’s ongoing commitment to refining its camera stabilizer systems through user-driven feedback and real-world testing. For cinematographers and rig operators who already rely on the TRINITY 2 for creative camera work, this software update promises smoother, more responsive performance tailored to modern production challenges.
