>>> Hi Jack,

I like the sideview of the swing that the individual exhibits on your swing analysis page. My only problem, though, is that it shows the batter's form before and after the arrival the ball--NOT AT COLLISION. Can you provide the precise moment where the batter makes CONTACT with the ball from the DIRECT SIDE VIEW shown in the instructional page. It would be a benefit for us all. <<<

Hi BHL

I’m afraid we can not show what you suggest with clips from broadcast video. The ball is in contact with the bat for about 1/2000 second. Broadcast video is shot at 30 fps with a shudder speed at 1/60 second in most cases.

Therefore, the bat can rotate through 30+ degrees of rotation while the shudder is open. To see the exact frame at contact would require a high-speed camera with the shudder speed set at 1/2000 second or faster. Otherwise, you may show the frame where contact was made, but not the exact position of the batter or bat at the precise moment of contact.
