THE RECORDING GUIDE

A natural walk.
A clearer picture.

You don’t need a studio. You need a steady camera, enough light, and room to walk normally.

Set up the view

1. Place the phone at hip height, from the side. Keep it still and level. Avoid a camera angle looking down or up at you.
2. Keep your whole body in frame. Leave room around your head and feet. Choose a distance that lets you walk across the image without cropping.
3. Use good, even lighting. A plain background and clothing that makes your legs visible help the system locate landmarks. Avoid backlighting.
4. Walk naturally across a level, clear path. Record several uninterrupted steps. Leave turns and pauses in the video; we look for usable sections.

Before you upload

Use an unedited MP4 or MOV, up to two minutes and 250 MB. Record one adult at a time, with their permission. Avoid filming bystanders or private details in the background.

If your video is rejected

A report needs enough visible, consistent walking. Try a steadier side view, more visible feet, better lighting, or a few more uninterrupted steps. We leave out measurements that do not pass their quality checks.

If walking feels painful, unsafe, or unusually difficult, don’t push through to get a recording. Consider appropriate professional advice.
