There are pictures posted below; The first picture is an image a pro sent me after chroma keying an image I sent him using dvMatte, flawless. The following pictures are my attempts at duplicating it (with a slightly different picture) the last image is my final product, aside from adjusting the brightness I think it came out pretty well. The only problem I still have is the blur which exists between the hair detail. You can tell that mine is much softer/blurred. I have tried every option in dvmatte and cant seem to adjust this. Any advice?

My specs are as follows:
-2.4ghz intel pro 2 duo
-4gig ram ddr3
-macbook pro
-final cut pro 7
-dvMatte 1.5
