SWAG:

 

9mm 1400 fps extracted shell case velocity ?=X

Simple math extraction speed =140 fps means the bullet would be 10' down range near the victims face. If we knew the frame rate (shutter speed) of the camera we could extrapolate the numbers better. There should be some field distortion where the projectile would be in the frame. I might be wrong, running on 4hrs sleep over a long 24hr day.

I guess we could chronograph the velocity of a ejected case . Mark the est distance of the case from the weapon then again work backwards to determine where along the path the projectile is based on the time interval of the event . I used 140fps as an ejection speed as an easy number and is would seem about right but we can't be sure.
