Markerless 3D motion analysis

Movement, measured.

A 3D skeleton from any video — no markers, no suit. Joint angles, frame by frame.

Markerless 3D motion analysis

Every frame, read like a coach can see inside it.

Upload a clip. Formak rebuilds your 3D skeleton and turns raw kinematics into prioritized, plain-language coaching — joint angles, symmetry, injury risk.

The pipeline

Three steps.

  1. Capture

    Record yourself on any camera and upload the clip. Add the sport and a brief scene note to sharpen the read.

  2. Reconstruct

    Markerless computer vision estimates a 70+ joint 3D skeleton across every frame of the movement.

  3. Analyze

    Formak reads the kinematics and returns prioritized findings — each with the biomechanical why and a cue.

Angle. Risk. Cue.

  • AngleMeasured at the joint.
  • RiskHow far from the range.
  • CueWhat to do on the next rep.
Built for

Everyone asks: how am I moving?

Athletes

Train the movement, not just the watts.

See exactly where your form leaks power or invites injury, and get a cue you can feel in the next rep.

  • Spot asymmetry and risk early
  • Track form across sessions
Coaches

An objective second set of eyes.

Turn a phone clip into measured, shareable findings — back up your coaching with numbers your athletes trust.

  • Measured angles, not eyeballing
  • Prioritized, plain-language reports
Curious

Just want to see how you move?

Upload a clip and explore your own 3D skeleton. No sensors, no studio — just your camera and a few minutes.

  • Works from a single clip
  • Plain-language, no jargon wall
Sports

Tuned per sport. More on the way.

Each sport ships its own biomechanics parameters, risk flags, and cues.
