The general advice is to turn off any "detail" or sharpening parameter =
when shooting greenscreen. The function of that feature is often to =
harden edges, and you want nice, naturally soft, antialiased edges to =
create nicer matte lines when you key your shot and place it over =
another.

Unless "conventional wisdom" has changed the past few years (I haven't =
done a lot of keying lately).
