Okay I guess it's a bit more complicated. I'm rotoscoping an object. Suppose it's a dog. Suppose it's a dog that's sitting and then stands. I want waves to emit out as the dog goes from sitting to standing, but I want previously emitted waves to maintain their 'birth' shape. Using a blur/colorama effect will update the all emitted waves realtime. Imagine if perhaps they were smoke rings. I don't want my smoke rings to animate as the dog changes position. Does that make any sense?

Yes. Use Colorama. Duplicate your layer, blur it/ add glow. Slap on Colorama and use your blurred transparency/ Alpah as the input parameter. Define your color stops for the "lines". Now all you need to do is animate the phase/ offset.

I have an animated mask and I'd like to emit waves (concentric outlines) from the mask. The radio waves effect seems to emit from a point control rather than from the mask itself, so I can't get the lines to really radiate out from the mask. Is there any way to get this effect?
