This is a developer recording tool, not a form shoppers need to complete. To try glasses live, open try-on.1. Open the camera
Camera settings appear after opening.
Physical references — measured validation only
Place a ruler in one plane perpendicular to the camera. Enter the ruler height visible from the top to bottom edge and the distance from the camera lens to that ruler plane. This ruler-plane distance is only for vertical FOV; it is not the subject’s distance during a clip. FOV is computed as 2·atan(visible height / (2·distance)).
The first PD/card sample is fixed to yaw-sweep.mp4. Choose a different canonical clip for the second sample and measure distance PD independently before each. Keep an ID-1 card flat against the forehead during both clips.

If needed, normalize WebM locally with FFmpeg. Keep the quick- filename prefix for quick recordings. This preserves source resolution and cadence, removes audio, and emits H.264/yuv420p:
ffmpeg -i INPUT.webm -map 0:v:0 -an -c:v libx264 -pix_fmt yuv420p -fps_mode passthrough OUTPUT.mp4
