This is broadly called natural image matting if anyone is curious enough to look into the last 20 years of research.
(wouldn't it be nice if every time a research topic pops up here that there would be a small list of the essential keywords to look for more background information?)
What's novel about this? If you have a background picture, you have all the info you need to identify your subject - just plain subtraction. I think this is what the Photo Booth app on my circa-2012 MacBook does, quite effectively.
Ex-VFX person here. Green screens are crap with hair, because its translucent the green/blue bleeds through which means that it has to be cleaned up by hand. Then there are the situations where there isn't a green screen. Again manual cleanup is required. Each frame needs to be cut out by hand. 24 times a second. The same with a difference matte. Cameras are noisy, so there is constant noise in the alpha channel. Thi…

This new method works well for partially transparent regions (hair) and allows slightly larger background movement and color overlap between foreground and background.
I think they baited you with their "loook, movement" replacement videos. As far as I can tell, their inputs have a fixed background and are of constant exposure and camera position.

Are there no tools that automate the cleanup of green-screen artifacts?
And Apple PhotoBooth deprecated this functionality too 32 bit debty.
