Editing MovieSchool 4 (section)

=== Multiple Zooming ===
Let's try making a movie where we zoom into each ligand that's not water.  In order to make this movie, I had to find a protein with suitable ligands, so you can do the same for your own protein.  Just replace the hard-coded residue numbers.

'''Goal:''' Make a movie that zoom into the three ligands, stays on that ligand for 2 seconds, then moves to the next.  I also want smooth zoom out at the end.  Don't let the length of this movie script throw you off, you've seen all of the movie commands and the initial commands are just loading the and making it look good.

# At 30 FPS this is then a 16 second movie.
# We look at the structure for 2 seconds, zoom in to each ligand
# and look at it for another 2 seconds, then, zoom out and look again
# at everything for another 2 seconds.
