How Tennis Video Analysis Works

From video to pose timeline

You upload a clip (web or mobile). The system tracks body landmarks across frames to build a pose timeline of your stroke.

That timeline powers the checks: shoulder turn, room at contact, and the swing path on groundstrokes; leg drive, reach, and shoulder tilt on serves; a short punch on volleys. Each reading is taken across all your swings. Foggy landmarks are ignored so a bad camera angle does not invent a flaw.

What the technique score means

The score summarizes hard form flags and softer quality signals into one clear number. It is tennis video analysis of your mechanics — not a ranking against named players and never a likeness comparison.

Every check stays on your pose timeline alone. Foggy landmarks are gated out so bad camera angles do not invent false flaws.

Explained feedback, not vibes

Every issue comes as explained feedback: what happened, why it matters, and a drill to fix it. Praise cards highlight what already works.

That is the difference between tennis video analysis software and a silent score: you leave knowing how to improve before the next session.

More room to improve

A free account includes one full analysis: score, skeleton, coaching, and coach chat on that report. Pro adds scored clips each month, and coach chat that refills with your plan.

Either way, the path is the same: film, analyse your tennis swing with AI, read the report, then practice the cue.

Share a report that recruits friends

You can share a redacted public link with score, video, and coaching cards — no private notes or raw telemetry. Friends see the result and can try the tennis video analysis app themselves.
