Comment (by Pat Gunn):
Unfortunately, we don't have the ability to rework how the file is saved;
typically microscopes have embedded software that write these file
formats; I am one of the maintainers of a piece of scientific software
that takes such files as input and does automated analysis on it. ffmpeg
ends up used by this through moviepy through pims.
It's frustrating that the avi format makes writing a good parser
nontrivial. If always reading the first packet for metadata (like the
palette) before doing a seek is sensible, that'd be great.
