Understanding Motive: Tracker within the Motive 3 Ecosystem

OptiTrack Motive: Tracker is a specialized software edition that operates within the comprehensive Motive 3 motion capture software platform. Access to the powerful features of Motive: Tracker is enabled through a specific license key. This allows users to leverage the core strengths of Motive 3 while unlocking the dedicated toolset designed for high-precision object tracking in engineering and research applications.

Flexible real-time streaming options

OptiTrack Motive: Tracker ensures flexible real-time streaming by supporting standard engines like VRPN and Trackd. For bespoke solutions, custom network interfaces can be developed using our free NatNet SDK, allowing tailored data delivery for your specific tracking applications and system integrations.

Open SDKs & API access

Motive: Tracker offers an open optical tracking environment with its adaptable architecture and complimentary developer tools. Gain access to data throughout the processing pipeline—from raw 2D images to fully labeled rigid bodies—and even replace the UI using our Motive API.

Recording and data management

Streamline data handling with Motive: Tracker’s updated asset and data management. This system automatically links tracked rigid bodies and custom markersets as metadata within their recordings. All project files are organized into a single folder, simplifying management for complex trials.
