I am using the Pan/Crop tool to create focus and movement 
with still images.  The tool only allows beginning and 
ending settings (size and center).  Additional movement 
requires multiple copies of the image with the ending 
setting of one becoming the beginning setting of the next.  
The problem is that this is not true.  When I type in the 
beginning settings to match the ending settings the 
location of the pan is offset - sometimes a little and 
sometimes a lot.  To get a smooth pan they have to be 
identical.  What causes this?  How do I make them identical 
or at least predicatble so I can get smooth transitions 
easily?
Thanks.
