So my very long title probably says it well enough, basically I've got some greenscreen footage of an actor, keyed it out, and now want to blur / 'soften' the keyed results. The thing is, I get a blur over the whole thing, including a blurred edge! I can't work out how to do an 'inner blur' if you follow me, that keeps the crisp outline of the key. Alternatively there might be a plugin that does similar beauty work?, any help very appreciated, thankyou!

Make a copy of your key, then try the Simple Choker, giving it a value of, say, 5.0
Then add a Fast Blur.

Combine that result with your original to get a nice matte (blurred inside, crisp outside), precomp it and use the new and improved alpha to your heart's delight.

thankyou I will try this also, I should post my other workaround too - I duplicate the layer, blur the original, then set the Trackmatte to the duplicated layer (which I make invisible).
