Creating a ghost – no green screen.
This is my set-up:
I have a clip of a girl walking to a corner, then kneeling down.
Then I have a clip of a guy in the same corner, sitting, waving his hands.
They both share the same exact background, the camera was locked. I need to make the girl (top layer) slightly invisible so that when played back – you can see the guy in the corner (real) and the girl walking through him (ghost)
Please help me, I’ve tried a dozen or so things.
Thank you so much.

Spoken like a hawkeye =)
If the shots are both locked down… stack them on top. Change blending modes of top shot… then lower opacity

I fully agree with your think before your shoot advice….

A re-shoot with a set for the Pepper’s Ghost effect could probably achieve what you want without any post-pro required. An explanation of the principles behind Pepper’s Ghost can be found at https://www.phantasmechanics.com/pepper.html
and at https://www.doombuggies.com/home.php for Disney’s Haunted Mansion effect.The guy is in the room with the furniture, etc. The girl in the other. Needs some really critical lighting of the background in the room where the guy is, in order to get the girl looking opaque in areas where you want her to be solid. Getting her looking transparent is simple – she will look transparent wherever the background (of the guy’s room) is brightly lit.
To get the girl to walk through the guy, use the principle of angle of reflection = angle of inflection (the distance of girl to mirror in one room = the distance of guy to mirror in the other room), and you will get the illusion of the girl walking through the guy.
