Filming guide

How to film.

The AI finds rallies from two signals: player movement and the sound of ball strikes. A good angle is one that captures both.

2–5m behind the baseline · 1.5–2.5m high · centered

Fix the camera

Use a tripod or fence mount. Handheld shake pollutes the motion signal.

Both players must stay in frame. Slightly elevated, centered behind the court works best.

Portrait crops the sides of the court and players leave the frame.

The AI separates rallies from breaks by the sound of strikes. Don't cover the mic or film from too far away.

Avoid

1080p / 30fps is all you need. 4K gives identical results and only slows down the upload.
