How do deepfakes manipulate images and videos so realistically?

Deepfakes use clever tricks to make fake faces look real in pictures and videos.

Imagine you have a photo of your friend smiling, and you want to make it look like they’re saying something funny, but without actually recording them. Deepfakes are like having a super-smart painter who can copy how your friend’s face moves when they talk or laugh.

Deepfakes use two main parts: one that learns how a person's face looks, and another that copies those movements onto a new face.

Think of it like playing with clay. First, the deepfake painter studies how your friend’s face changes, their eyes squinting, mouth moving, head tilting. Then, the painter uses that knowledge to make a new face move in the same way, even if it's someone else’s face.

This new face is then placed onto another video or picture, like putting on a costume. The deepfake artist makes sure everything lines up, the skin tone, the lighting, and how the eyes blink, so it looks just like the real person.

It’s not magic, it's like having a robot that copies your friend’s face move-by-move, making fake videos feel super real!
