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.
