Green screen solutions

I recently did my first green screen work and, of course, it's left a lot to be desired. An issue I'm currently try to resolve is a green halo that occurs around my talent's hair. I can't get it to key out, but it's not subtle enough to let fly by.

A benefit of mine is this: after I do the best I can with the green screen, I'll be shooting it off a television. The intended effect is to make it look as though I'm recording an actual live news broadcast off of a television. So this gives me some playing room.

Does anyone have any advice? Is there a Vegas tool similar to Photoshop's smudge? I'm thinking I can create a parent track and put some cookie cutters over the outline of her hair where this problem is occuring. I've tried that already with some saturation reduction, reducing the greens, etc. So far, nothing has been satisfactory.

Any and all advice welcome! I know it's not gonna be perfect because I fouled it up in production, but I'd like to salvage it as much as absolutely possible. Sadly, I can't just shoot it again because I no longer have access to the talent and I have to complete the video by next week.

Thanks!
 
you shot it wrong then. always try to get the green/bg out of focus and the subject in focus. if everything is sharp it kinda just blends in and you dont want that. id suggest bringing up the greens as much as possible (while keeping the subject safe) and then play with the threshold. also your lighting could've been bad.
 
Oh, I absolutely shot it wrong. I'm just trying to salvage it best I can with the Sony Vegas plug-ins at my disposal.
 
You can try applying a chroma blur before the greenscreen (which you can still do by changing the order of the FX). You can also manipulate the chromakey High and Low sliders.

If you have a lot of spill on the actor, which you may, especially if you shot her close to the greenscreen (you need good distance), then it'll make things tougher.

You can try secondary color correction.

As for shooting a TV screen? Probably not necessary. You can achieve the same thing with proper application of the TV Simulator FX and various other FX for sweetening.
 
Chroma blur helps a lot. As David also mentioned, use the secondary CC effect. Select a portion of your screen and increase the saturation. That helps me sometimes.
