It's the other way around.
Using a mask with color correction always has the potential for edges like
this. It depends on the mask and that's true for any software.
The difference here is Howards method, which did not use keying at all, but
instead used simple math to breakup the image into primaries and
secondaries. This however, does not allow for changes in the "width" of the
hue you are controlling.
I was mimicking the Adobe way completely. The Hue & Sat effect has a hue
keyer built into it, and I use it often, and so it was important for me to
keep it.
I'm about to publish a new version that builds the various parts up in a
different way and produces, what I think, are better, smoother results. If
you can send me a frame of your car, I can take a look what it does to it
first, and only then upload to Nukepedia.
