Hello guys,

Ok, I created a short intro in after effects, but I created it at a resolution of 650x500 and tried to export to flash swf. Well, the file size is too big (680 kb).

I want something smaller in file size, so I need to change the resolution to half of that (325x250). Well according to after effects help, you can nest a composition in a smaller composition to make your composition stretch down… but it only stretches it down, it doesnt change the file size. (aka renders it at the same resolution I started at, but display at half teh size)

How can I actualy make it smaller without starting all over again??

THanks:rap:
