If your animations are only changing the data symbols (or lines) (and if 
SVG is an acceptable format), you could try using my (experimental!) 
gridSVG package (I expect an SVG file would be a lot smaller).

If you can generate a tiny version from some of your data and send me a 
file showing the sort of animation you are doing, I can have a go at 
mocking up an SVG version.
