Swing Video Upload
Upload a video of your swing from the face-on, down-the-line, or sport-specific angle. SwingVantage segments the video into phases and provides coaching notes for each phase.
What it is
Swing Video Upload turns a phone clip into a structured, phase-by-phase read of your motion. Record from the face-on, down-the-line, or a sport-specific angle, upload it, and SwingVantage segments the swing into its natural phases and attaches coaching notes to each one — so you can see where in the motion the problem actually originates.
Your video is processed locally in your browser. When you run an analysis, only sampled still frames — not your full video — are sent to the AI vision provider for review, and the frames are not retained afterward. Your original footage never leaves your device, and it is never used to train a shared model.
Treat the read as a confident starting point rather than a measurement: single-camera video is interpreted heuristically and sharpens as you add data. For on-device pose tracking and a rotatable 3D reconstruction, step up to Motion Lab.
Who it’s for
- Players in video-first sports (tennis, pickleball, padel, baseball, softball)
- Golfers who want a phase-level look to complement launch-monitor data
How to take full advantage
A step-by-step guide to getting everything out of Swing Video Upload.
- 1
Film a usable angle
Record face-on or down-the-line (or your sport’s standard angle), full body in frame, steady camera, good light. A clean clip is worth more than a long one.
- 2
Accept the privacy notice and upload
Confirm the on-device processing notice, then upload. Only sampled frames are sent for the read, and they aren’t kept.
- 3
Step through the phases
Open the phase-by-phase timeline and read the note on each phase. Find the earliest phase where things go wrong — that’s usually the real cause.
- 4
Cross-check with data
Where you have launch-monitor or tracker data, compare. When the video and the numbers agree, your confidence goes up.
- 5
Graduate to Motion Lab when ready
For a measured 3D view, film the same rep from two angles ~90° apart and run it through Motion Lab.
Pro tips
- →Film the same angle every time so reads are comparable session to session.
- →A two-second clip centred on the actual swing beats a thirty-second clip with setup and reaction.
Good to know
Every video read is a heuristic estimate that sharpens as you add data — a confident starting point you can act on today. For full on-device pose tracking and a rotatable 3D reconstruction, see Motion Lab.
- • Single-camera reads are heuristic estimates, not lab biomechanics — labelled as such throughout.
- • No medical, injury, or tour-grade claims are made from video.
Frequently asked questions
Is my video uploaded to a server?
Your full video is processed on your device and is never uploaded or stored on our servers. When you analyse, only sampled still frames are sent to the vision provider, and they are not retained afterward.
What angle should I film from?
Face-on and down-the-line are the workhorses for most sports. Film full-body, steady, in good light. Consistency of angle matters more than which one you pick.

Phase-by-Phase Timeline
Each sport has its own swing phases. Golf: address, backswing, transition, downswing, impact, follow-through. Tennis, pickleball, padel, baseball, and softball have sport-appropriate phases.
