Motion Analysis – 2D

Video for motion analysis has always seemed a bit redundant to me.   The fact is that videos provide only 2-dimensional data, regardless if there are 2 (Specialized!), 3, 4…  Most cameras are only fast enough for < 80% accuracy, and two millimeters error using “line-drawing” tools can alter function ten-degrees or more.

Dartfish and Quintic software are different, because they provide kinematic functions like trajectory and digitization.

I recently purchased the Quintic Biomechanics/Coaching Software, in route to getting the Biomechanics 9.03.  Hopefully, we can get more US bike-fitters using this phenomenal product.

Best utility is for demonstrating postural considerations and gross positioning issues.
