effect help - looney toons fade?

[pete321]

I'm trying to do an effect where it's sort of like a fade in, but it starts in the very center of the screen,
and grows out from a small circle into 100% opacity, then goes back to the small centre while it fades out. Sort of
think loony toons. I want it to sync to the sound of a heart beat if that might help some people visualize.

Any ideas?

much thanks in advance.

you can use the cookie cutter FX ( use "circle" then key frame the "size" )
for the circle small to large or large to small effect

use the Iris wipe transition. You can feather the edges and also determine the center start point. Just drag the event fade handle over and drop the iris wipe on the fade area of the event to replace the fade.
