| A few things I'd suggest: Use Levels set to alpha, and play with the alpha gamma or setup. I often now use two instances of Keylight, or one instance of Color Key followed by Keylight. The first instance is a garbage pass: set the controls so that you have a small ring of green around your object to be keyed. Follow that with Keylight, and then you only have to fix a small area. Or, use your Intermediate Result, followed by another instance of Keylight to work on your edges. That's how Intermediate Result is intended to be used.
