OpenTrackIO
With OpenTrackIO, camera and lens data is transmitted in real time with exceptional precision. Accurate compositing can be achieved with no additional equipment, and seamless integration with leading rendering engines, including Unreal Engine, is possible.
OpenTrackIO is also compatible with genuine Sony E-mount lenses, delivering flexibility to meet diverse shooting needs.
What is OpenTrackIO?
OpenTrackIO is a new protocol for transmitting camera‑tracking data, established by the SMPTE RIS‑OSVP group.
To faithfully reproduce precise VFX (visual effects) in virtual production, it is essential to increase the accuracy of information such as the camera, lens, position and orientation, and timing, and to achieve rigorous synchronization between the physical and virtual spaces. OpenTrackIO provides a complete dataset that meets these requirements and transmits the data to rendering engines in real time.
Unreal Engine, widely used as a rendering engine, officially supports this standard starting from version 5.6.
By combining FR7 with Unreal Engine, realizing virtual production without additional hardware, plug‑ins, or configuration is possible.
Camera Tracking Data
Benefits
Conventionally, additional camera tracking devices, lens encoders, and specialized lens calibration work were required. With FR7 Ver.4.00, these steps are eliminated. Camera and lens position, orientation, and high-precision lens data are transmitted directly to Unreal Engine, enabling accurate compositing and synchronization of live footage with CG backgrounds. Timecode synchronization further ensures alignment of video signals and tracking data, contributing to greater efficiency on set and improved image quality.
Conventional Solution
OpenTrackIO Based Solution
* OpenTrackIO compatibility with 3D rendering engines will expand in the future.
Expanding the System with OpenTrackIO
Even more precise compositing of live-action footage and CG backgrounds can be achieved with lens and stage offset calibration. By combining the FR7 with CalibFX®, the camera’s position and orientation, relative to the virtual space, can be fed back to the camera with a single button press, immediately updating the relative tracking position data.
Example Use Case
Sony’s OpenTrackIO Compatible Lens
We plan to support 44 genuine Sony E-mount lenses* as OpenTrackIO-compatible options, enabling selection of the ideal lens for a wide range of shooting scenarios.
* As of February 2026
Compatible CG Rendering Engines
The list of compatible CG rendering engines are subject to change without notice.
