One thing I learned about video is that you need to tape multiple angles to pick up errors and or dysfunction. Much of the side view filming is for performance, while shooting from behind and in front can capture more medical problems and compensations. When I do analysis I watch all multiple speeds because slow motion is often deceiving, showing errors that may not be the true cause of performance loss. I picked up a few tips from a few coaches over the years and facial expression often shows injury, too much stimulation, and breathing patterns. The reason I film from behind is to see ankle action and foot mechanics. From the from I check shoulder and knee balance, and from the side range and projection angles.
