I would think a coarse grain parallelization is what is indicated.  This 
is to a degree, how rendering is done.  Some number of frames at a time 
distributed to some number of nodes.

Basically have converters running on N nodes, each getting start/stop 
frame indexes. From there, each does the conversion.  A final process 
stitches the frames together.
