    Doing some basic green screen editing of a video clip…see attached… have keyed out green via keylight, set the clip black to 15 and clip white to 50 in the Matte view to get the best minimal settings, applied the “chatter” and “green spill”, shrunk image by about 1 or 2 pixels, set the, and fiddled with “screen gain” between 103 and 110…can’t remove the thin jagged white edge around the image… see 2nd clip

    Are you viewing in full resolution? I just had a similar issue in FCP. It was driving me crazy. But, when I rendered the file it was fine. I was using Hawaiki <b style=”font-family: inherit; font-size: inherit; -webkit-text-size-adjust: 100%;”>Keyer 4.5.
