yes i tried -Vc (it's the same as -t video -c i guess?). it's still pretty
big.

i don't find the swf specification anywhere but i could imagine the shape
encoded swfs simply store rectangular bitmap areas which get drawn where
something has changed on the screen. couldn't shape encoded swfs use some
aggressive jpg compression then for these bitmaps? or are they already
compressed with something like rle and jpg wouldn't make much difference?

could video encoded swfs use sorensen or something like that?
