As said, you should get my AdvancedDespill macro on Reactor. Sometimes I preform an edge extend, but it depends on the footage I'm working with. What I usually do is to use the DeltaKeyer just to create the Alpha. I suggested to move look at the intermediate result to see if it was a despoiling problem. That Blue fringe you see is also a matter of despilling. Too bad the Final Result doesn't deliver a clean result. I wonder, would it be possible for an a alpha of the original Final Result key be able to applied to the Intermediate result so that we are pulling the clean image without the more out of control spill? In DaVinci, I used the GoPro CineForm RGB-16 bit codec with Alpha export on, and that’s the only codec with an alpha channel available for me on this computer, so I can’t test other options.Thanks! That does work, save for the fact that three is now a blue fringe that I can't seem to eliminate.

I messed with every material setting that had a positive value, and it changes nothing.I set the alpha in my video’s node in the Shading tab’s N-panel to both Straight, and Premultiplied.I set Light paths → Clamping both to 0.

Even though there’s nothing that would get in the way to prevent light from passing through, etc
