green screen issue

[upper veldt]

im trying to do an after effects green screen then add 3d layers to the video but there is still some green color spill at the edges of the video. how do i get it removed?

theres still some green color spill (although its not fully opaque)

you can increase a bit the softness

or if you have the plugin you can use keylights preset than remove some edges etc

you can use key cleaner
