Well, it's certainly possible but I'm not sure it's worth doing. I tested with the imagemagick cli and the enlarged filesize ends up non-trivial (though much smaller than the original)....

Thanks for the report! I've never tested JPT with anything animated before. There's a new version in the works which completely replaces the image handling backend and also exposes more...

You could bypass JPT, just write the HTML directly. You can write HTML in markdown.
