    In looking at old posts concerning this issue, since I’m having similar issues with keylight, Dave LaRonde appeared to have a good formula for this issue. But when I look to see his advice, there is nothing there. It just says apply 2 keylights, though it looked like he had a more detailed. If you’re out there Dave, can you help us out? Your method seemed to be the way to go.

    This is really great – extremely helpful. However, I’m not sure I’ve totally got what you’re saying right as regards the lower layer and the effect to achieve there. Basically I’m still getting some green “bleed” on the edges of my subject and your explanation sounds like that shouldn’t be there. Do you have this posted anywhere in greater detail? Maybe a walkthrough somewhere?

    David, I just discovered this post and although it’s over two years old was still completely relevant and an incredible help. Just wanted to say thanks for sharing such a useful tip.

    I just read this brilliant post and can see it working while I write it down in my notebook. Just sublime, brilliant and so simple.

    The spill suppression bonus is just darn good stuff too.

    O.K., I’m gonna put myself out there and look like the fool. I love the way this post SOUNDS, but I still need some help. I’m relatively new to green screen. We don’t have the BEST light kit in the world, a couple soft boxes and a couple brolly boxes, but it’s been getting us by, at least for web/youtube videos where are videos are primarily based. The blacks have a graininess to them that I smooth out as best I can, and additional smoothing is added naturally when exporting in H.264 and uploading to youtube, they look fine. I’m having some issues at the moment however and I would love to give this post a try and the simple “just get it till it looks gray” is still a little vague for my experience level. What should I be playing with? can we break this down a little more? Thank you SO much!

    Can someone please explain what this means:

    “Fool with the lower layer’s Keylight settings until it looks like the subject looks fine, but is over a grayish, washed-out chroma key background. It’ll take some doing, but you will have gotten it to the point where Keylight’s spill suppressor is working. That’s good, because the Keylight spill suppressor works darned well.”

    I guess the layer that is keyed out is made as good as possible before it is duplicated and already looks as fine as I can get it…
    Thats why I do not understand what exactly I need to do with the layer underneath.
