Motion Lab
Motion Lab is the browser-based 3D motion analysis tool in SwingVantage that turns your video into a three-dimensional avatar and timeline, letting you rotate, scrub, and measure your swing without any installed software.
Motion Lab runs entirely in the browser using on-device pose estimation and a WebGL 3D renderer. After processing your video, it displays a rigged 3D avatar that mirrors your detected body movement, with a frame-by-frame timeline, angle overlays, and sport-specific fault annotations. You can rotate the avatar to view the swing from any angle — down-the-line, face-on, or top — even if your video was only recorded from one direction. The analysis inside Motion Lab is deterministic first: angles and sequence findings come from the rules engine; AI depth is optional.
Example
After uploading a face-on tennis video, Motion Lab renders a 3D avatar that can be rotated to a down-the-line view, revealing a late racquet drop that was hard to see in the original footage.
Why it matters
Seeing your movement in 3D from any angle is more informative than a single-camera clip and was previously possible only in professional labs.

- Pose EstimationPose estimation is the computer-vision process that detects the positions of major body joints (keypoints) in each video frame, producing the skeleton that SwingVantage uses to measure angles and movement patterns.
- Skeleton OverlayA skeleton overlay is the on-screen visualization of detected body joints and the lines connecting them, drawn over your video so you can see exactly what the system tracked.
- Swing DecodeSwing Decode is SwingVantage's golf-specific analysis view that breaks the swing into distinct phases — address, takeaway, top, downswing, impact, and follow-through — and annotates each phase with the relevant mechanics detected.
- Landmark TrackingLandmark tracking follows the position of each detected body keypoint across consecutive video frames, creating a time-series trajectory for every joint that enables timing and velocity measurements.
