Sony Vegas Pro 10 chromo keyer and windows 7

I am going to be working with green screen alot in my next project and i was wondering are there any better ways to chromo keyer becaus in vegas i still get that very faint green all around the person.
i use 2 effects to chromo keyer first i use chromo blur and then i use chromo keyer.
Are there any other effects in vegas pro 10 that i can use to get a cleared cut outline of a person.
is there an extra plugin i use that worls woth vegas.

Also i know this may sound very stupid but i will ask it anyway.
i am still using Windows XP. i have 4GIG of RAM but obviosly XP only sees 2 that is why i am thinking of changing to window 7. Currently i am running XP 32bit can i change to Windows 64bit and still use vegas pro 10 32bit or do i have change vegas also. please advise

Thanks John for the quick response. with the newblueFX plugins do you have to buy the whole package or can you buy specific plugins

Thanks John for your help I purchased the New Blue essentials II that has the chroma key effects and it works great thanks for introducing me to New Blue FX.

I am currently running vegas pro 10 just upgraded from vegas 7, a big jump i see, not just in the look and feel but also my computer is feeling the extra processing power needed to run pro 10. It seems when i am in vegas pro 10 working on a project if i move away and open a folder or media player vegas stops responding and i have to go to task manager to close it down .

Also i am running Windows XP Professional. I want to move to window 7 then my computer can use all 4GIGs of RAM rather than just the 2,5 GIGs that it sees right now with windows XP

I have to agree with Bill here, if you light the set just right, with plenty of space between your subject and the greenscreen as well as good back lighting, Properly white balance your camera before the shoot "In the set you'll be shooting in". As long as you don't show feet and need shadows, the Vegas chromakeyer wcan do a pretty good job. But the lighting has to be right so you have no spill, or it's useless. Hope this helps, Danny Hays
