How slow is it now, and how fast do you want it to be?

One possibility is to generate frames in parallel... though if you're
recording a video of a sequence of operations, each of which depends on
the previous, it may not be possible to parallelize.

I have a toy project that generates animations of a 3D model
parametrized over time. It generates .pov files and runs POVRay to
generate frames, then calls ffmpeg to make the video.  This is
parallelized with std.parallelism.parallel, and is reasonably fast.
However, ffmpeg will take a long time no matter what (encoding a video
is a non-trivial operation).
