Velocity Analysis

Previous  Next


The Velocity Time Analysis allows you to create graphs based on velocity over time of up to 50 markers at a time.  You can graph any of these markers relative to another marker.  Additionally, you can graph the velocity data relative to the starting position by selecting the Normalize option.  This option will calculate an average of the first n frames and then subtract this velocity from each consecutive frame creating a “change of velocity” graph.


The following formula is used to calculate the velocity:
