Record an athlete with a single phone. ARC Motion AI reconstructs full-body movement frame by frame, measures true speed and technique, and returns a coach-grade report — no lab, no sensors, no wearables.
From a single video, ARC Motion AI produces three layers of insight — the raw motion, the physics, and the verdict.
Every joint tracked across the full run, with live speed and distance rendered on top — the technical detail the eye can't catch, made visible.
A true velocity curve over the whole effort — acceleration, top speed and the point where an athlete starts to fade.
Top speed, speed maintenance, gait symmetry, technique and lower-limb stiffness — scored against biomechanical norms, not opinion.
A four-step pipeline that runs on ordinary footage and scales to thousands of athletes.
A single phone from the side — even a handheld follow-along shot. No rig, no markers.
Full-body pose is tracked frame by frame and stabilized against camera movement.
Speed, cadence, contact and flight time, joint angles, symmetry and stiffness — measured and modeled.
An individualized, plain-language report with a five-dimension score and targeted training advice.
Most tools need a fixed tripod, a calibrated scene and specialist hardware. ARC Motion AI works from the video coaches already take.
Even when the camera pans to follow the athlete and the background scrolls, we recover real ground speed and distance — where ordinary methods read close to zero.
Cadence, contact/flight time, joint angles and symmetry are directly measured. Speed and distance are estimated and clearly labeled — and can be calibrated to ±3% with one known result.
Raw video to a full individualized report, fully automated — so an assessment that took a specialist an afternoon now scales to an entire cohort.
A handheld clip already reveals technique, cadence and symmetry — a full report in minutes.
Fix the camera and give it a real reference — speed and distance calibrate to ±3%.
A dedicated setup unlocks the full competition-grade biomechanics stack.
Every metric traces to peer-reviewed sport-science literature — over 40 studies across five dimensions of movement. Not a black box.
Peak vertical force, vertical displacement and leg stiffness derived from the sine-wave impulse method.

Motion AI sits where sport, fitness and rehabilitation meet — multi-billion-dollar markets across the US, Europe and beyond, all compounding at double digits. The technology thesis is already proven; athletic performance is the lane still wide open.
Market figures: Grand View Research, Fortune Business Insights, Allied Market Research (2024–2025).
At-home training is where the growth is. Virtual and connected fitness is racing from $34B in 2025 toward $312B by 2034 — and every at-home training or rehab device needs a movement-analysis engine behind the camera. That is exactly the layer ARC Motion AI provides.
The model is already validated at scale: publicly-traded leaders in at-home movement care, billion-dollar private valuations, and a $285M category acquisition in 2026 mark a fast-maturing market — all of it clinical rehab. Sport and athletic performance is the lane none of them run.
Run ARC Motion AI as a branded assessment product for your school system, federation, club network or gym chain — web-based, mobile-ready, and priced to scale to entire cohorts.
License the biomechanics engine behind a tablet, kiosk or app — the analytics layer for at-home training and rehab hardware, without building a computer-vision team.
Deployed across a provincial sports association and a leading national university — every clip below is real analysis output.
Whether you run a school system, a club, a gym network, a clinic — or you're building the hardware people train on at home — we'll show you a live analysis on your own footage.
