Overall

Ensure you are connected to a stable Internet connection. Video upload may fail with a poor connection.
Do not move cameras once you've passed the calibration step. If you accidentally moved a camera, start a new session.
The checkerboard is only used for calibrating the cameras, you can remove it after successfully completing the calibration step.

The camera on the back of the iOS device, rear-facing camera, is the one used for recording.
Position the cameras to avoid segment occlusions.
Avoid people in the background. Our algorithms are built to handle this, but it will make them slower and error prone.
Avoid having the participant exit and re-enter the capture volume.
At least two cameras need to see every body segment at all times during the movement. Two cameras is sufficient for many tasks, but tasks where segments get occluded may benefit from an additional front-facing camera.
For a two-camera setup, cameras at 30-45° off of the line facing forward from the participant is typically best. Pure sagittal views do not work well due to limb occlusion.
