Another green-screen question - cropping

Look at the green screen sample here:

raw sample

keyed sample

and notice the the right and left edges missed the screen.

I know I could pan/crop this and get rid of that, but is there a way to use a mask or something to tell it "everything in this mask is chroma key'd" or whatever?

And if so, would I do that before or after chroma keying this video?

I'm not even sure if I'm explaining this correctly, but hopefully some of you will know what I mean not what I say...

:)

OK - I was able to use the cookie cutter square to mask it off, but is there a better way, or is this the recommended method?

You can use a bezier mask, but a cookie cutter is easier.

if you've got $5000 laying around get Fusion 5. :-)

you are talking about garbage masks, where you can just draw a polygon around whatever needs to be keyed out, but not sure how that would work in Vegas ( never had to do it ). what you did is probablly the best way in vegas, especially for that example.
