Instructions for Best Results

Finding the right spot

Find an uncluttered place (e.g. no shoes on the ground, pizza boxes, furniture, etc...)
Make sure there is a relatively flat path, approximately 10m / 30ft long
Make sure feet are visible (i.e. no tall grass)
Look for an area with even lighting. Avoid strong backlight
Look for an area with minimal background distractions (uniform or distant background)

Setting up to capture the video

Hold camera vertically (portrait mode)
Hold the camera about 1.5m / 5ft off the ground
Stand approximately 3-4m / 10-13ft from subject - note subject should take up about 2/3 of the frame
As subject walks, rotate camera about vertical axis to keep subject centered in frame
For best results the subject should be wearing shorts or form-fitting pants (e.g. yoga pants, running tights, etc...) and a short-sleeved or sleeveless top

Capturing the video

Ask the subject to walk in their comfortable/usual manner
Ask the subject to proceed back and forth four times (two laps)
Start capturing video AFTER subject begins walking
Stop capturing video BEFORE subject stops walking
Alternatively, edit your video so that it starts and stops with the subject walking
