There is a remarkable new software tool out there called "FakeApp" and it morphs the features of a photograph (or photographs?) on to someone else's face in video. It moves seamlessly with the other face, matching lighting changes and mimicing all of the face expressions.
You can see some examples here:www.reddit.com/r/deepfakes/
As you may see some are using it to put star's faces (like Katie Perry) on porn actor's bodies.
This post has details in how to get and use the software:www.reddit.com/r/deepfakes/com…
Could be interesting to see some face swaps of female bodybuilder videos... Just sayin'
