OptiTrack Motive:Body offers uncommonly simple workflows and impeccable body tracking data, including precision finger tracking in large volumes with high subject counts—perfect for indie studios and AAA production houses alike.
In Depth
One-click subject calibration
Calibrate new skeletons in an instant, with a single button click, for subject setup that is unprecedented in its speed and simplicity. You can even do so with multiple subjects in the volume at once. And when you’re ready to send your data to MotionBuilder, OptiTrack Motive:Body will export a pre-configured Actor, with skeletal proportions and markerset ready and waiting on the other end.
Precision finger tracking
When used with Flex 13 or Prime Series cameras, OptiTrack Motive:Body leverages the industry’s most precise 3D point data and our new kinematic labeler to produce impeccable finger tracking data that shines in large volumes.
Expanded subject counts
Motive:Body’s kinematic labeler has been optimized to track higher subject counts, for capturing more people in larger volumes.
Kinematic labeling
OptiTrack Motive:Body uses a clear understanding of each of the subjects’ skeletal structure to produce marker labels. This approach delivers tremendously accurate marker labels, providing stunning real-time output, even during close interaction.
New markerset templates
Whether you solve your skeleton in OptiTrack Motive:Body, MotionBuilder, Visual3D, or another third-party tool, Motive:Body’s new markerset templates provide more verbose marker data for better continuity and a cleaner solve.
Setup is easy
OptiTrack Motive:Body reduces system setup time by up to 75%. Aim Assist, auto-masking, one-click rigid body creation, versatile hardware and the industry’s longest range cameras make even large systems easy to setup with just one person.
64-bit, multi-threaded architecture
OptiTrack Motive:Body was designed from the ground-up to leverage the native power of the latest Windows 64-bit OS and Intel/AMD 64-bit processors, enabling tracking of more objects and actors, longer recordings, larger file sizes, and support for hundreds of cameras per system.
Comprehensive data management
Plan and execute complex motion capture sessions with OptiTrack Motive:Body’s new asset and shot management systems. Drag and drop your shot list from Excel, Google Docs, or whatever application you use to build out your shot list. Throughout the shoot, Motive:Body will track your assets and assign each to the takes they were captured in as file metadata—perfect for managing large production shoots.
Flexible real-time streaming
OptiTrack Motive:Body gives users the choice of turn-key pipelines or complete access to develop customized output for unique requirements. Stream mocap via our free MotionBuilder plugin, or write your own interface with our NatNet SDK.
Ikinema Action for Maya
Stream characters into Maya in real-time with IKinema Action, which offers a super-fast marker solve and straightforward pipeline into the industry’s most popular animation package.Watch the tutorial
Open SDKs
OptiTrack Motive:Body’s flexible architecture and free dev tools create the world’s first truly open motion capture platform, offering access to data at any stage in the pipeline—2D camera data, centroid data, unlabeled markers, labeled markers, rigid bodies, and skeletal data. You can even replace the Motive:Body UI completely and directly control system operation in your application with the Motive API.
SMPTE Time Code
Users with an Ethernet-based OptiTrack system and the eSync device can stamp recorded and streamed motion tracking data with SMPTE Time Code for integrating with other media and data in post.
External sync in/out
Synchronize your system to almost any signal or source with the eSync 2 or OptiHub devices. Cameras can be sync’d to external sources such as a professional video Genlock signal, and can also be triggered to record from general purpose inputs and software commands. Motive:Body also broadcasts a simple XML UDP packet with Time Code and take data that elegantly provides start/stop record for triggering remote devices, such as reference video cameras.
System health monitoring with indicators
OptiTrack Motive:Body’s extensive health system monitors real-time performance throughout your pipeline, from camera operation to the quality of your takes. Prime Series users will enjoy Motive:Body’s native integration of the camera status indicator ring, which provides real-time indication of every camera in the system’s activity and health.
Sync’d reference video with 3D overlay
Drop any motion capture camera into the video reference group in the camera manager and transform it into a full-frame reference camera. Calibrated and synchronized reference cameras provide an overlay of 3D marker and bone data, creating the perfect visual reference for real-time previs and assistance with post.
