Compare Swings
Put two swings side by side — yours then vs. now, or your swing next to a model — to see exactly what changed.Last updated
In short
Compare lets you view two swings side by side and in sync, so differences jump out. Use it to see your before-and-after on a fix, or to line your swing up against a reference.
Step by step
- 1
Open Compare
Go to swingvantage.com/compare and pick the two swings you want to view together.
- 2
Sync them up
Line the swings up at the same moment so you are comparing like with like.
- 3
Spot the difference
Watch them together to see exactly what changed in your positions and motion.
- 4
Act on it
Take what you learn back to your fix and drills, then retest again.
What Compare is for
Seeing two swings together makes change obvious in a way a single clip cannot. It is the visual partner to your retest — proof you can actually watch.
Ways to use it
- Your swing before a fix vs. after, to confirm progress.
- Your swing next to a model move you are working toward.
- Two of your own swings to check consistency.
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.
Frequently asked questions
What can I compare?
Two of your own swings (e.g. before and after a fix), or your swing against a reference, viewed side by side and in sync.
How does this help me improve?
It turns “I think it changed” into something you can see, which makes the fix concrete and motivating.
What kind of video gives the best results?
Film from the side (down-the-line or face-on), in good light, with your whole body and the full swing in frame. Hold the phone steady or prop it up. A 5–10 second clip of one swing is ideal. Normal speed works; for golf, baseball, and fast-pitch, 60 fps sharpens the moment of contact.
