A web site with physic videos?

[lawtonfogle]

I am trying to find a (free) website which has med. to high quality videos of real world physics, such as a bat hitting a baseball. The catch is, it needs to be with a motion camera with time in milliseconds, so one can measure how long one object is in contact with another.

This is not actual homework, but my physics teacher asked me to help find a video like I described.
