    Acceleration in Scaling - CS4


      I am using CS4 and have used scaling in some still photos to achieve the "Ken Burns" affect.  The result is as expected.  However, I would like to ease in and out of the motion by smoothly changing the acceleration of the motion.  I have read the CS4 manual looking for instructions on doing this and I can't find it.  Nothing is mentioned about acceleration adjustments to scaling and motion.  I can achieve it in a manner by setting keyframes at various points in the clip but the acceleration does not change smoothly.  I want to start the motion slowly, build to the maximum and then gradually slow it at the end of the frame.  Any asistance would be appreciated.
