Skeleton Overlay
Also known as: pose overlay, keypoint visualization
A 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.
SwingVantage renders the detected skeleton on top of the video frame by frame, making the pose estimation output visible rather than invisible. This serves two purposes: it lets you verify that tracking was accurate before trusting the numbers (if the hip joint jumps around, something went wrong), and it lets you observe your own movement in a stylized form that is easier to analyze than raw video. In the Motion Lab 3D view, the skeleton is projected onto a three-dimensional avatar for more intuitive analysis.
Example
After upload, the skeleton overlay shows a hip landmark drifting off the body at the top of the backswing — a sign of tracking loss, not a real movement.

- 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.
- 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.
