These three ran on wavespeed-ai/image-face-swap-pro, a dedicated face-swap model that takes no prompt.
It took one real face from our character bank and put it onto a real frame of a Doe creator who filmed herself in her car.
After lining each result up with the original frame, 0.0% of the pixels outside her head changed, so the car, her hand, her top and the light are the original video.




Cropped in, each new face is smoother and glossier than the real skin around it, and that is where a swap still shows.
The lip-sync step redraws the face again at 480p, so the moving test is the real judge.

All three faces are real women from our character bank, placed on another real woman's body, and I have not checked that we have the rights to either.
The locked script says "I'm half black", and the bank holds no Black woman in this age range, so a brunette from the bank means changing those two skin lines with you first.
These three swaps cost about $0.08.
