Recording guide
Camera setup is the single biggest factor in rating accuracy. A well-framed video scores 90+; a zoomed or shaky video can score as low as 20.
Set the phone behind your own baseline
Stand the phone at your end of the court, looking down the court at your opponents — so you are recorded from behind, nearest the camera.
Most people prop the phone at the far end to film themselves head-on. It looks better, but your side of the court ends up small and partly hidden behind the net, which is exactly where our positioning measurements lose accuracy. Filming from your own end keeps you in the clearest part of the frame.
Other angles still work — tap yourself after upload and we will analyse whatever we can measure reliably, and tell you when we cannot.
Behind YOUR baseline, wide angle, all corners visible
Zoomed in / partial court — misses key player positions
Setup checklist
- Put the phone behind YOUR OWN baseline, so you're filmed from behind — this is the setup we measure most accurately
- Full court in frame — all four corners visible at all times
- Behind the baseline or an elevated sideline — not on the court
- Stable mount — tripod, fence clamp, or stable surface (no handheld)
- 1080p at 30 fps is plenty — 4K and 60 fps only make the upload bigger
- 2–3 minutes of real points (at least 90 seconds) — enough rallies for a reliable read, and under the 1 GB limit
- Avoid: Zoom in or pan during play — it keeps us from tracking you reliably
- Avoid: Record through a fence with obstruction — use a gap or angle around it
- Avoid: Backlit or very dark lighting — the court lines need to be clearly visible
Phone tips
- iPhone: Use the native Camera app, 1× zoom, landscape, 1080p at 30 fps (Settings → Camera → Record Video).
- Android: Set resolution to 1080p (not 4K), landscape, lock exposure before recording, use a clip-on tripod mount.
- Placement: Fence top, bleacher rail, or a Joby GorillaPod-style clamp at 6–8 ft elevation gives the best court coverage.
