Hi people!

I'm about to make a jump into keying for a current project.
We have a small test image that has likely been sharpened inside the camera. How do you deal with this in your keying workflow?
What are great ways to reduce the sharpening around the relevant edges without blurring the whole image?
I've sketched a little comp to show what I'm doing at the moment but there may be simpler and/or better solutions for this problem out there.

here's the cropped source image for the comp. It won't upload.

What was it shot in? That looks more like color accuracy and compression issues. For example, usually DSLR's record in a 4:2:0 H264 codec, which is heavily compressed and doesn't have enough colors to pull a good key.

You could try Secondman's KAK keyer or the technique I've described here.

I usually do an edge detection on my regular key and use it to blend in those alternative keying solutions whenever I have weird or defocused edges. So maybe that works for that halo as well.
