Keying Problem on intersecting edges
on Sep 2, 2019 at 3:51:30 pm

Hey there,

I have encoutered this problem dozends of times but I don't really know if there is a name for this. The key itself looks ok, but where 2 people are intersecting you get this bright edge that travels along the intersections. (see image)

Is there a clever way to get rid of this? The chokers just take away the edge even where it has to stay and if I start masking the effect it is veeery timeconsuming.

Any ideas?

Thanks very much in advance!

Not sure which keyer you are using but sometimes Edge Color Correction can help here.

Also I sometimes pre process my green footage in a sub comp. I use Hue Saturation to boost only the green channel saturation and also sometimes add a denoiser. Then in the main comp I pick that now much more saturated green....this helps define the edges better.

I almost always use Edge Color Correction in Keylight and I can make any slightly green or brighter edge areas match the shirt they are wearing or a background color etc to make a more convincing composite.
