Hello all,

I have been using after effects pretty heavily for a couple of years, and I have never been able to keyframe the standard glow effect off.

Take a look here:

I want to keyframe the glow to look like the image on the left. I am pretty sure I have tried every combination of settings to get around this with no luck. My options now are to 1) go purchase a trapcode glow plugin 2) duplicate the layer and cut between 3) figure out what I am missing. I was hoping you could enlighten me (option 3). Urgent project, thanks.

Got a screenshot of the offending timeline with the other layers visible?

Another thing to keep in mind is that you can put most effects on an adjustment layer above the layer you want effected and key frame the adjustment layer's opacity to zero to turn off the effect..

The only gotcha there is that you would need to precomp the layer with the adjustment layer, or else every layer below the adjustment layer would be effected as well.

As always, there seems to be a miilion ways to do most things in After Effects.. This is just another perspective.

I realize this is a bit late, but for anyone else that is curious:

Duplicate the layer and set the blending mode to "Add". In the glow settings change "Composite Original" to 'None' and "Glow Operation" to 'None' (this just gives you the glow).

Then just animate the opacity or intensity.
