Golf Swing Analysis
Swing review from one strict view: address, top and impact markers, with lead-arm extension, knee flex, head sway, shoulder-hip separation and spine angle.
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 golfer’s chest faces at address.
Face-on (strict). Head sway, lead arm, knee flex. Pick this OR down-the-line, not both in one clip.
How high, and how it should sit
Framing
Golfer, hands, club and ball area visible from address through finish.
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 at about hip height.
- 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 higher. Slow motion saved at normal speed works if you enter the recorded frame rate.
- From published guidance
- Resolution
- 1080p
- From published guidance
- Orientation
- Landscape or portrait both work.
- From published guidance
- Lens and zoom
- Use the 1x zoom.
- From published guidance
- Lighting
- Bright, clean conditions: daylight or strong light, a clear background and a visible target line.
- From published guidance
- Stability
- A stable tripod, not handheld video.
- From published guidance
- Calibration
- No calibration is needed for angles. Distances and speeds need a scale (see Calibration).
- From published guidance
Before you start
- After upload, set golfer handedness and the camera view.
- Confirm the Address, Top and Impact markers before exporting or comparing results.

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.
