Use cadence as a same-pace baseline instead of a universal score.
Running form analysis
Turn a phone video into a running-form baseline.
Upload a steady side or rear clip. ViSIn tracks the runner frame by frame and turns the result into plain-language measurements you can compare over time.
No app install · short preview without signup · source video not retained
A result you can read before opening the charts.
Compare side-to-side timing and confirm patterns in another clip.
Track how the estimate changes at similar pace and camera placement.
Three steps, no sensors or markers.
- Record. Keep the full runner visible from the side or rear.
- Detect. The 26-point pose engine includes heels and toes.
- Compare. Save a baseline and repeat at the same pace later.
Side view
Review rhythm and projected joint motion.
Estimate cadence, contact timing, vertical motion, knees, shins, feet, elbows, and trunk angle from several visible strides.
Rear view
Review alignment and symmetry.
Estimate pelvic-line tilt, lateral trunk motion, 2D knee alignment, step width, and repeated crossover patterns.
Useful measurements, honest limits.
ViSIn produces 2D video estimates. Camera angle, pace, lighting, clothing, blur, and occlusion affect the result. Use the report for training and repeatable comparison—not diagnosis or medical advice.
