Uploading & Recording a Swing

Step by step

1. 1

   Open Motion Lab

   Go to swingvantage.com/motion-lab/studio. On a phone, you can also tap Analyze and choose Motion Lab.

2. 2

   Pick your sport

   Choose your sport (golf, tennis, baseball, softball, pickleball or padel) and the motion, such as a swing or a serve. Then upload an existing clip from your camera roll or record a new one.

3. 3

   Frame the swing

   Film from the side with your whole body and the full motion in frame. For on-screen guides, film with Record a swing (Record Assist).

4. 4

   Capture one clean rep

   A 5–10 second clip of one swing in good light beats a long, shaky one. Slow motion is not required.

5. 5

   Let it analyze

   Motion Lab reads the clip on your device. You get your main issue, one fix, a practice plan and a retest target, all from one clip.

Why the video matters most

The single biggest factor in a good analysis is a good video. A clear, side-on clip of a full swing gives the AI everything it needs; a dark, cropped, or angled clip forces it to guess.

Spend ten extra seconds on framing and you will get a dramatically better report.

The ideal swing video

• Angle: film from the side (down-the-line or face-on), not from behind a fence or at a steep angle.
• Framing: your whole body and the full swing arc should stay in frame from start to finish.
• Light: bright, even light. Avoid strong backlight that turns you into a silhouette.
• Steadiness: prop the phone up or have someone hold it still.
• Length: one swing, roughly 5–10 seconds. You do not need slow motion.

One clip, one full analysis

One clip gives you the whole analysis: a summary, your main issue, one fix, a practice plan and a retest target. Visual Proof replays your motion, with a 3D skeleton and avatar when the clip allows it.

An AI second opinion, under One Fix, is optional. Frames leave your device only if you start it.

Record Assist

Choose Record a swing to film with Record Assist, the in-app recorder. It gives you framing guides, a shake warning, and frame-by-frame review so your capture is clean the first time. It is the easiest way to get a usable swing.

How accurate is it?

Every result that comes from watching your video is a well-reasoned starting point, not a lab measurement. Treat it like a sharp-eyed coach giving you their read, then check it when you practice.

Accuracy depends on what you give it. A clear, well-lit, side-on video of a full swing produces a far better report than a dark, cropped, or partial clip.

When the analysis is unsure, it tells you so rather than inventing a number. Honesty over false precision is a core principle.

Your video and your privacy

Your swing is yours. Motion Lab reads it on your device: body tracking runs in your browser, and your video file is not uploaded for analysis.

Frames from your video leave your device only through optional features you choose. The AI vision review, which you start yourself, sends a small sample of still frames to a third-party AI provider; our servers pass them through without storing them. If your device cannot read a clip, you can agree to an optional cloud re-read of a limited set of still frames.

We do not sell your data or use it for advertising. When you sign in, your sessions, progress and saved analyses are kept in your private account and synced across your devices. A saved analysis can include one still frame for its swing trace. Your video files are not uploaded unless you choose to share one for training, an optional box offered only to signed-in adults filming themselves.

You can review, export, or delete what you create from the Data Center at any time.
