Hi,
  Sorry for the delayed reply, I've been away from email while using
up vacation days that were on the chopping block...

The "vmdmovie" plugin itself can be driven from an external
loop, so it can be easly called from a parallel rendering script.
We did this extensively for the work described here:
  https://doi.org/10.1016/j.parco.2020.102698
  http://dx.doi.org/10.1016/j.parco.2015.10.015

Rather than driving "vmdmovie" directly however, most of the cases
where this was done were instead driving the "viewchangerender" plugin,
which already has tie-ins to the "vmdmovie" plugin to drive it.

If you're still interested in doing this, I've attached old
scripts that did this for some fairly simple VR movies we rendered
a while back, in a couple of different variations. I have lots of
other variants floating around, but this one was easy to locate.

Best,
  John Stone

I have MPI compiled into VMD and a simple parallel script works fine- it would be nice to use some of the features the plugin provides like 'ppmtompeg' and baked-in animations.
