Ameteur greenscreen key with stop-motion
Warning: Pretty inexperienced using After Effects
So to test it out I recorded a very short brickfilm sequence with green card behind to act as a mini greenscreen. I have no additional lighting available apart from the room light and an omnidirectional touch table lamp (not used). I used to have more lighting, again fairly basic, but I don’t have access to it at the moment and the results were the same with it.

With key, I used a random background image off Pixabay:
b.pngAdmittedly the lighting environment is dreadful which may be a factor but I don’t want to keep buying things just because I don’t have access to them.
Could this be corrected in the camera or AE? I manually white balanced it, macro on and camera on Program mode. Compact Nikon Coolpix S9700. I’d upload GIFs of the sequence but had trouble exporting.

If you’re looking to key your image, there are a few ways. I’ve made three example attempts here with Color Range, Keylight, and copies of the obsolete Color Key effect. So, turn one example off in the layer stack, turn another on, and take a peek. 10806_legokeying.aep.zip

I managed to pull an okay, fast key with only using…
Screen gain — 130
Screen Balance — 50
Then
Clip White — 8
Screen softness — 5
But since you have the original footage you will probably get away with less softness.
And now the most important part.
Replace Method — SourceIt’s the soft color choice that introduces the artifacts you see on your key. So I would say in 99% of the cases use the “Source” option for Replace Method.
