Video analysis tells you your wrist is wrong. But it can't tell you which muscle caused it. The EFFECT is visible. The CAUSE is hidden inside your body.
CAMERA LIMITATIONS
Your downswing takes 250ms. At 30fps, a camera captures just 7-8 frames of it. The critical micro-timing that separates a pro from an amateur happens BETWEEN those frames.
Standard camera
Slow-mo camera
Our IMU sensors
Our EMG sensors
WHAT'S INVISIBLE
Which muscle fires first — core or forearms? Only EMG knows.
How hard each segment pushes, and when. Invisible to any lens.
When muscles tire, others take over silently. You can't see this switch happen.
Peak-to-peak transitions happen in 20-50ms. Camera captures 1 frame in that window.
Shoulder and hip rotation rates that determine power. Only measurable by gyroscope.
OUR APPROACH
We don't replace your camera. We add the two layers it can never provide: precise timing and muscle activation. Together, they answer the full question.
WHAT happened
Body positions, angles, posture. The visible layer.
HOW FAST it happened
Angular velocity, acceleration, timing between peaks.
WHY it happened
Muscle activation, firing order, compensation patterns.
