Go back and read my original response. The trick is to use
the time silder with only two "keyframes", one at the beginning
of the shot, and one at the end. Then set up you zoom at the
beginning, note all the setting numbers, and go to the end and
enter exactly the same numbers. Do NOT set any key-frames
anywhere else in the timeline of the shot. Your zoom will stay
rock-solid for the length of the shot.
