Motion capture software for full body animation and biomechanical analysis. ARENA and Expression share the same installer, so users with licenses for both only need to download one or the other.


The DirectShow Filter only supports Slim 3U, Flex 3, FLEX:V100, and s250e cameras (up to serial M001694).
Integrate OptiTrack cameras into existing DirectShow compatible applications, such as those built using OpenCV.
The DirectShow Filter should not be used at the same time as other OptiTrack applications due to camera control interference.



Create startlingly realistic facial animation in minutes. Expression and ARENA share the same installer, so users with licenses for both only need to download one or the other.


With an expanded feature set, Motive 2.3.7 advances its precision human and object tracking capabilities across VR, animation, movement sciences and robotics applications.
Notable updates include: Active rigid body speed improvements with up to 66% less latency, IMU sensor fusion improvements, enhanced Continuous Calibration, and support for 250+ cameras in one volume. Additionally, this version of Motive introduces active or passive ‘Anchor Markers’ to both aid Continuous Calibration with disconnected volumes, and provide peace of mind regarding origin drift.
Sample data for use in Motive 2.x or lower from movements such as jumping jacks, golfing, running, etc. Also includes take files used in the tutorial videos.
System Specs: Motive 1.8 beta & Motive 1.10 beta
