Users, Yes, I've come to the conclusion that the movie commands are inadequate for what people need and want. My plan is to implement a dedicated camera matrix for each frame, and optionally, a chain of matrices for each molecular state, so that complex animations can be generated without resorting to programming.
In the meantime, scripts which establish mdo/mappend/translate commands are the only way to go. Don't forget about "mmatrix store", which can establish a standard starting point for frame 1...
