Quick question, When doing the keying using keylight 1.2, the result looks fine however the original footage, 1080p 25f has a "dragging effect" dont know how to call it exactly therefore I have pink and red edges around the moving arm of the actress... (see picture attached)

You don't say which version of AE you have, but the Feather Masks feature in CS6 can be a real friend here. What you're seeing is motion blur - the video was shot with a slow enough shutter speed that the arm movement is too quick to be captured in focus, hence the blur.
I've had good luck using a combination of the Roto Brush and masks to clean this up. It's tedious, though. Good luck...
