Overview of OptiTrack Motive 2.3.7
OptiTrack Motive 2.3.7 is a point release in the Motive 2.x series, developed by OptiTrack (NaturalPoint, Inc.), a leader in optical motion capture systems. Motive is the flagship software for real-time tracking of human and object motion using infrared cameras, passive/active markers, and rigid bodies. It supports applications in VR/AR, animation, film production, movement sciences, robotics, and engineering, delivering sub-millimeter accuracy and low-latency data streaming. Released in late 2023, version 2.3.7 focuses on stability enhancements, hardware compatibility fixes, and workflow improvements for USB-based camera systems (e.g., Flex, Slim series). As of September 25, 2025, the Motive series has advanced to version 3.x (with Ethernet support for Prime/Primex cameras), but 2.3.7 remains relevant for legacy USB setups and users with valid licenses through December 7, 2023. It runs on Windows and integrates with SDKs like NatNet for custom applications.
Key Features
- Tracking Capabilities: Real-time 6DoF rigid body and skeleton solving, with support for up to 250+ cameras in large volumes.
- Data Management: Record, edit, and export in formats like C3D, FBX, BVH, and CSV; includes video overlay for reference footage.
- Integration: Native support for force plates (AMTI, Bertec, Kistler), EMG (Delsys), and peripherals; streams via NatNet SDK to Unity, Unreal, MotionBuilder, etc.
- Calibration Tools: Continuous Calibration for ongoing accuracy; Anchor Markers to prevent origin drift.
- UI and Workflow: Customizable layouts, hotkeys, and panes for live/edit modes; API for bypassing the UI.
What’s New in Motive 2.3.7
This update builds on 2.3.0’s foundation (e.g., active rigid body latency reductions up to 66%, IMU fusion improvements) with targeted fixes for reliability and compatibility. It advances precision tracking for VR, animation, and robotics without major overhauls.
