How to film a game

Tripod and position

Put the phone at the halfway line, on the side of the court, centred on the half-court line. If there are stands, go to the back of them. Use a tripod or a clamp and do not move it during the game.

Height

Two to three metres above the floor. Higher sees over the players in front. A tripod that reaches 2 metres works, or a clamp on the stand railing.

Angle and framing

Film in landscape. Both hoops must be fully in the picture, with a little floor beyond each baseline. Do not zoom. The app shows a court outline to line up with, and tells you when the court is in frame.

Battery

Plug in a power bank before you start, turn Do Not Disturb on and lower the screen brightness. If the phone gets hot, the app warns you: move it out of direct sun.

Storage

A basketball game needs about 5 GB. The app checks before tip-off and tells you if space is short. Recording keeps going if the phone locks.

Common mistakes

• Filming in portrait. The court does not fit.
• Too low. Players in front hide the shots.
• One hoop cut off. Half the baskets are missed.
• Zooming in. The AI loses the court lines it uses to measure distance.
• Filming into a bright window. Players become silhouettes.
