Full-swing analysis using only high-speed video. No sensors, no markers. Built for MLB, collegiate, and elite development programs.
Traditional bat sensors and lab-based mocap systems miss the full picture. Theia3D captures bat + body together in the environments where hitters actually train.
Most systems lock coaches into markers, instrumentation, and controlled spaces. Theia3D works in cages, bullpens, and anywhere teams train, giving coaches true flexibility.
Theia3D captures the full bat path while simultaneously measuring joint angles, sequencing, and whole-body mechanics, letting coaches connect movement to performance.
Traditional motion-capture tools create friction every time a new athlete steps in. Theia3D keeps sessions moving. Swap hitters in seconds without interrupting training pace.
Theia3D turns everyday training footage into clear, usable swing data with a fast, three-step, markerless workflow. No sensors, no lab setup, and no extra workload on staff—just trustworthy data coaches can put to work right away.
Use a standard wand or your proprietary Theia3D calibration board (shipped at purchase) for flawless and fully automatic motion capture setup. This minimizes errors and optimizes data collection, ensuring top-tier accuracy.
Capture multi-camera video in your environment with subjects wearing their everyday clothing. No preparation or spandex suits required. Allow natural movement in the environments that matter.
Leverage Theia3D’s motion capture technology to track 124+ keypoints for precise 3D skeletal models. Load videos and calibration files into Theia3D to examine a single pitch or swing, or use Theia3D Batch to automatically analyze large datasets for efficient measurement reporting. Export data in multiple formats, including .c3d motion files, allowing seamless review and reporting of key metrics in customizable workflows.
Leading performance programs trust Theia3D to deliver accurate movement data from real training environments—helping coaches tailor training with confidence.

Theia’s markerless tracking platform is backed by 50+ peer-reviewed studies and validated across a wide range of sports and motion protocols. The bat-tracking expansion builds on the same modules used by elite biomechanics labs and performance institutes worldwide.
Tested on more than 300 athletes and over 2,000 swings, the system consistently delivers bat-angle errors under 3°, aligning with Theia’s proven markerless motion-capture accuracy.
Yes. Theia is designed for real-world environments — indoor cages, outdoor turf, bullpens, and on-field training.
A high-speed video setup (300 fps or higher) with 6+ synchronized cameras, and Theia3D with the bat tracking add-on.
A single session setup is all that's required. Athletes rotate with zero setup or calibration between swings.
Yes. Theia supports roster-scale throughput without re-instrumentation.
Measure the bat. Measure the body. See the full picture in the environments where hitters actually train.
