Why are deepfake videos becoming so realistic and convincing?

Deepfake videos are becoming super realistic because they use clever tricks to make one person look like another, just like when you put a mask on your face and suddenly you’re a superhero.

Imagine you're drawing a picture. You have the background, then you add the person in front. Deepfakes do something similar but with videos. They take a lot of pictures (or video clips) of someone’s face, like when you snap a photo of your friend from all angles. Then, using a computer, they put that face onto another person's body or mouth, kind of like putting on a new outfit.

Just like how you get better at drawing by practicing more, computers get better at making deepfakes when they see lots of examples. They learn from all those faces and movements, so they can copy them almost perfectly, like a mirror that doesn’t just show your face but also moves with you! That’s why deepfake videos look so real and convincing today.
