Quick roto 4k green screen

Hi there,

I need some roto artist here to remove background. It is close up so I somehow need sharp edges as much as possible.

I have 4k shot, about 116 frames/25 fps https://www.dropbox.com/s/lywalt6osktqh0g/SH030_cut.mov?dl=0

Please, show me your previous work and how you can deal with motion blurred videos.

Let me know.

Thanks.
