Can green screen subject be used as an animation?

I’m a beginner to Unity, so I hope this isn’t a overly dumb question. Can a video of a person on a green screen be used as an animation instead of a created 3d character? I dress up people like Zombies and put them on a green screen instead of creating characters in Maya, etc… I can’t figure out how to take my real subjects and use them instead of fake characters…Is this possible? Can I save them as some sort of animation asset? Thanks for reading…

Yes - the frames of the video can be used as a sprite animation. Look into the 2D learning content for further guidance.

how about with sound-sync… eg, a talking sprite… @theANMATOR2b
