3D marker tracking
Marker tracking is the foundation of ARENA’s motion capture technology. Using reflective markers placed on actors and props, calibrated cameras create a cloud of 3D points. These 3D points can be labeled and exported to other applications or mapped to ARENA's skeleton solver for tracking full body motion. Captured actor and prop data can be exported to 3D animation and analysis packages using standard 6DoF digital file formats.
Skeleton solver
ARENA utilizes a powerful skeleton solver for real-time translation of marker data, automatic marker labeling, and exportable joint-angle data. By optionally saving motion capture data as a skeleton hierarchy, ARENA enables you to use that data in applications that often don’t include skeleton solving, such as game engines and lighter animation packages.
Support for multiple actors
When bundled with 12 or more motion capture cameras, ARENA can track two actors in the same volume—perfect for capturing realistic interaction between characters.
Prop tracking
In addition to one or two actors, ARENA can easily track props through the creation of custom rigid bodies, which can be saved or streamed alongside body motion capture data.
Simple learning curve
ARENA is uniquely user-friendly, with simple setup, capture, and export procedures. Most users are able to capture and export motion data the same day their system is delivered. Comprehensive video tutorials guide new users from beginning to end of the mocap process.
Automatic skeletons & marker assignment
A process that used to take hours is now reduced to minutes. Generate automatic skeletons and marker assignments with the easy-to-follow Skeleton Wizard.
Simple camera calibration
ARENA can calibrate up to 24 USB Flex series cameras or 48 S250e cameras. Wanding and calculation are typically complete in ten minutes or less.
Single user control
With user-defined timers for capture sessions and real-time 3D previews for feedback, a single user can be both software operator and actor.
Comprehensive tutorial videos
Online tutorial videos are available to guide users through every step of the motion capture process—from camera setup and calibration to data cleanup and export.
Preview work inside of ARENA
Live 3D previews allow you to monitor marker, skeleton, and mesh tracking during capture, for real-time feedback on tracking quality. Ensure that your data is exactly what you want before saving and exporting to your rendering software.
Data cleanup and editing
ARENA’s graph editor includes simple tools to clean up your mocap data before export to your animation software. Tools include marker swapping, gap filling, smoothing, track moving, and free-hand track drawing. Include a calibrated scene camera in your volume for a powerful reference during cleanup.

Industry standard data export
Export using industry standard C3D, BVH, and FBX formats to a variety of animation packages, including MotionBuilder, Maya, 3ds Max, Softimage, Cinema 4D, Daz Studio, Poser, LightWave 3D, and others.
Real-time streaming plugins
ARENA streams live to MotionBuilder, 3ds Max, and Daz Studio for real-time data preview and capture within the animation software. Create additional real-time plugins for your preferred animation package or game engine with OptiTrack’s NatNet SDK.
