A deepfake is a video that is processed to overlay one person’s face on top of another. One of the earlier deepfakes to go viral was this Conan O’Brien interview in which Bill Hader does impressions of Al Pacino and Arnold Schwarzenegger. At key moments, Bill Hader’s face is post-processed to resemble each celebrity.

But the video below breaks new ground, as the face is changed in real time, on demand, with much more detail than the Bill Hader fake.

Nothing good can come of this. Like counterfeiting.
