Softball Pitching Analysis
Fast-pitch and slow-pitch delivery analysis from side and rear views: stride, sequencing, release position, arm circle and head stability.
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: target line.
Side view, throwing-arm side, perpendicular to the target line. Stride length, sequencing, joint angles, release position and height.
How high, and how it should sit
Framing
Full body, ball hand, stride landing and the rubber, from set through recovery.
The 50–75% 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
- Side: hip-to-chest height, level and stable. Rear: not stated.
- From published guidance
- Distance
- Side: far enough away to preserve the entire arm circle. Rear: offset from the ball path. No numeric distance is published.
- From published guidance
- Frame rate
- 60+ fps. Select the camera’s ORIGINAL capture rate, not the exported playback rate. Timing confidence is capped low at 30, medium at 60 and may reach high at 120+. Selectable capture rates: 30, 60, 120, 240, 1000.
- From published guidance
- Resolution
- 1080p recommended
- 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
- Increase light. Avoid baggy clothing that blends into the background.
- From published guidance
- Stability
- A stable mount.
- From published guidance
- Calibration
- No calibration is needed for angles. Distances and speeds need a scale (see Calibration).
- From published guidance
Before you start
- Set the delivery first: athlete, fast or slow pitch, side or rear view, hand, pitch type, pose model and capture frame rate.
- For slow pitch select Slow Pitch before analysis.

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.
