Quicktime might be overkill for this purpose, since even the best MPEG
compression algorithm will not do as well as one which can recreate the
images from a connection table with coordinates.  More importantly, reducing
the animation to a Quicktime movie eliminates the possibility of interactive
exploration, for example, viewing the movie from a different angle.

Quicktime is slick, and would allow the movies to be used in interesting
ways, but I don't think it's right as a distribution medium.

At the risk of making a commercial plug, I will note that our Chem3D Viewer
is freely distributable.  A Chem3D owner can create a single-frame model or
a movie containing any number of molecules and give it to a colleague with a
copy of Chem3D Viewer, and the colleague can view the structure(s) from any
angle.

Moving ever closer to that oh-so-fine-line, for those still interested in
Quicktime, I note that it would be a natural direction for future
enhancement of Chem3D to support the creation of Quicktime movies.
