OptiTrack Motive 3.4: Professional Motion Capture Software

Motive 3.4 is the latest version of OptiTrack’s powerful motion capture software, designed for applications ranging from biomechanics research and film production to real-time tracking and virtual production. This release introduces significant enhancements in skeletal tracking, camera SDK support, and usability improvements .

Key New Features in Motive 3.4

Camera SDK for Linux

  • Linux Support: Camera SDK now supports both Ubuntu and Fedora operating systems

  • Easy Integration: New sample application simplifies camera integration into custom software solutions

  • All Modes Support: PrimeX, VersaX, and SlimX cameras support all video modes including new Duplex Mode

  • Color Camera Ready: Prime Color cameras work in example applications with no modifications

  • Simplified Reference: Additional simple application for stripped-down reference code including eSync 2 debugging

Range of Motion (Bone Refinement)

  • Precision Skeleton Calibration: Refine joint placement and scale bones to better match a real performer’s movement

  • Guided Routine: Actor completes guided Range of Motion routine moving each tracked bone to compute accurate joint locations

  • Session Reusability: Joint locations can be reused across multiple sessions by updating constraint locations (not bone lengths)

  • Workflow Integration: See documentation for detailed instructions on completing Range of Motion refinement

Improved Marker Placement Guide

  • Enhanced Builder Pane: New green marker visual for easier marker placement definition

  • Joint Axis Lines: Visual guides to more clearly define where joint markers should be placed

  • Marker Type Information: Comprehensive documentation for different marker types used to create skeletons

Licensing Updates

  • Tracker License Expansion: Motive:Tracker licenses now support standard (non-trained) markersets

  • Max Ray Length: Solver setting returns, allowing exclusion of long rays in big spaces to reduce jitter and improve tracking stability

Interface Improvements

  • Continuous Calibration Pane: Previously part of Info pane, now has dedicated pane for easier access

  • Distance Display: Added ability to display distance between any selected 3D objects (previously only displayed when markers selected)

  • Hardware Notes: User-definable Notes property now available for all hardware devices

  • Spine Model Update: New skeleton spine model (introduced in 3.3) renamed to “7 Spine Segment” and now default when creating new skeletons
