Video Analysis

Tips for good video Analysis:

 
1- Be midway down a run. Full view top to bottom.
2- Have subject make turns heading down the fall line. Half width of Nastar turns
3 – Keep camera steady. do not move the camera, keep the person in the view
4-  As the person goes by be at least 20 feet away, you now move camera panning
as the person goes by 180 degrees.
5- do the same  2-3 as they have your back to the camera.

This will capture a frontal, side (upright, stance etc) and back.
