Keying problem—Bad green screen and Bad lighting

Hi,guys here.An old question comes again:How to get smooth edge lines of matte when do keying work with bad greenscreen shot?(bad green screen and bad lighting….footage :HD 1920 x 1080)

I know one method: colorspace,linear to Ycbcr —–>blur rgb channel( g and b channel ,value 4)—–>colorspace,Ycbcr to linear.
This method may do help in some case,but in my bad greenscreen shot,the reflection of green screen is a trouble,and actors’s clothes are effected.The matte edges of keying result is ugly.

The director may think that compositer can do anytings by roto drawing even wtih bad footage.

May guys catch waht I mean according to the pics.I wanna get smooth matte edge by keying,espically with those bad greenscreen,etc….I am eager to receive advices about keying.
