So there's this recording of this 3d rubik's cube I have( It's onstantly rotating and changing shape). The BG is pure white, and the cube has clear black outline. But if I try to key out the cube using color or luminance, the white parts of the cube itself also gets keyed out.
Is there a way I could somehow limit the keying to only outside the outlines? Maybe any way I could choose how many pixels in an area to remove at once? (the bg is a huge area while the cube stickers are small areas)
I remember seeing something like this in After Effects if I remember correcly.
Attached is a screenshot of the vid (https://imgur.com/wOIsoEJ). Thanks in advance!
