Squat Analysis
Double-leg and single-leg squat control from a front clip: depth, bottom pause, knee alignment, pelvis tilt and trunk lean.
How far has this tool been checked?
The measurements were checked against computer-drawn athletes whose true answers are known exactly. That shows the arithmetic and the event rules are right under clean, controlled conditions. It does not measure how well the body-tracking model sees real people (water, loose clothing, crouching, fast limbs) and has not been compared with a lab or a coach’s stopwatch. Treat the numbers as an aid, and use the confidence label beside each value.
Where the camera goes
Seen from above. Angles are measured round from the front of the athlete; 90° is square-on from the side. Reference line: direction the athlete faces.
Front view, straight-on. Depth, knee alignment, pelvis tilt, and support-side control.
How high, and how it should sit
Framing
Whole body from feet to head for the full rep.
The 70–90% band is our own guidance. No published source gives a camera distance in metres, so use it as a starting point and adjust until the whole movement fits.

All the camera settings
Every setting shows where it came from.
- Camera height
- Tripod around waist height. Hand-holding is discouraged.
- From published guidance
- Distance
- No published distance exists. Stand back until the whole athlete fits with a small margin, so the athlete fills roughly 70-90% of the frame height. Use the 1x lens and move your feet, not the zoom.
- Our guidance
- Frame rate
- 60+ fps. 60 fps or more. Slow-motion footage saved at normal speed works if you enter the recorded rate.
- From published guidance
- Resolution
- 1080p
- From published guidance
- Orientation
- Landscape or portrait both work.
- From published guidance
- Lens and zoom
- Use the 1x lens with no digital zoom. Avoid ultra-wide and fisheye lenses.
- From published guidance
- Lighting
- Bright, even lighting with minimal shadows.
- From published guidance
- Stability
- Tripod or fixed support, level with the horizon.
- From published guidance
- Calibration
- Enter athlete height in metres before reviewing the report; it sets the pixel-to-metre scale.
- From published guidance
Before you start
- Start tall.
- Descend under control to the true bottom, then stand back up without stepping out of frame.
Cues for the athlete
Plain coaching cues, one thing at a time.
General
- Control the descent and reach your true bottom.
- Stand up without stepping out of frame.
Why camera position matters
Research behind these rules.
2D angles are only trustworthy when the limb moves in the plane the camera sees. Camera-side joints are measured more accurately than far-side joints, and timing is only as fine as one frame.
