This gizmo lets you preserve the original grain from your plate after keying.
Sometimes making a matte after Denoising then copying it into your RGB plate just doesnt cut it. I usually like the fine edges result I get from the IBK keyer and would like to get back that original grain i removed from my foreground elements after keying.
