When I do animations and I want more control than animated GIF's, I output
single frames into, say, PNG format then assemble them into an AVI or MPEG
using a third party video program such as videomach.  A simple way to
generate series of frames is as follows:

Assume your animation depends on a natural number parameter t...

myDisplay[x_][k_]:=Display[filename<>ToString[x]<>".png",k,"PNG",ImageSize->500]
Do[
....
....
Show[.........(my graphics),DisplayFunction->myDisplay[t]];
....
.....
.....,{t,1,tmax}]
