This sounds pretty cool.  Any chance you could share the final movie with us?

This is possible from the movie timeline (right-click store with
state, for a given object) or the command API using the 'mview'
command:

# make a blank movie over 110 frames
mset 1x110

# goto frame ten and set obj1 and ob2
frame 10
mview store, object=obj1, state=1
mview store, object=obj2, state=100

# goto frame 110 and set obj1 and obj2 in their final states
# pymol will interpolate everything else for you
frame 110
mview store, object=obj1, state=100
mview store, object=obj2, state=1

This creates a 110 frame movie where in frame 10, object one
transitions from state 1 to state 100 over 100 frames.  Likewise,
object 2 transitions from state 100 down to state 1 over 100 frames.

Hope this helps.
