Hasta La Motion!

Someone please explain to me how to rid those annoying edges in keylight. A lot of people are lyric about keylight and it does a sweet job overall, but whatever I do, I keep getting light edges on dark subjects with a black background.

I can waste hours with my keys and still have those edges forfeit all my effords to make it look good. So apparently there’s one trick unrelated to the rest of the key that I am just not getting.

Quick example:

Black background, nevermind the bad key
Any dark background makes this key look bad

It is as if the physical edge is fixed by a thin black line (which is okay), followed by a big whitish smear. And when compared to the alpha channel, this smear is often supposed to be pretty much invisible, but it is painly visible over any dark background, whether I unpremultiply or not.

Clipping blacks ofcourse cleans the dust in the background, but it hardly touches the light borders even they appear on very transparent area’s, according to alpha.

I can do some edgeblur and lightwrap, although dark backgrounds hardly have anything to wrap, but to overcome this I must really make unrealistic smears and blurs.
