How to film

A usable clip comes before any priority. Opposite batter's box, chest-facing, full body, phone still.

Before recording on iPhone: Settings > Camera > Formats > Most Compatible.

1. 01Put the phone in the opposite batter's box, facing the hitter's chest.
2. 02Hold it near hip height, roughly perpendicular to the hitter (±15°).
3. 03Show the whole body, head to feet. After any letterbox crop the hitter should fill about a third of the picture, at least about 300 px of body height.
4. 04Landscape. Prop the phone still — don't hold it.
5. 05Use 60 fps or higher when you can. Bright, even light. Avoid backlight.
6. 06Film three or more swings with the same setup. Nobody else in the frame.
