I need to animate the following images from the stroke glow text to fill glow text and from fill to stroke. I believe there should be several ways that this can be done, but I would like to create the effect of a light bulb going from dim to bright (as I am using glow and stroke effects in the images below, possibly giving the fill a higher glow radius) when animating from stroke to fill and vice-versa for the opposite. How can this be done?
Duplicate the text layer. Make the bottom one fill only, and the top one stroke only. Animate the opacity of the bottom layer. I figure two frames from 0% to 100% opacity.
