I use runwayml.com (I paid for premium lol) to make custom passthrough scenes like this. Download from eporner or wherever (4K max resolution) and trim to find the best angles (and no man hands in the scene) and this site uses AI to create a green screen (just need to place dots on areas you want removed). I am sure there is a better way but this is how i have done it. I uploaded an example to gofile.
