AI Can Now Detect Deepfakes by Looking for Weird Facial Movements

Here's a scenario that's becoming increasingly common: you see that a friend has shared a video of a celebrity doing or saying something on social media. You watch it, because you're only human, and something about it strikes you as deeply odd. Not only is Jon Snow from Game of Thrones apologizing for the writing on the show's last season, but the way his mouth is moving just looks off. This is a deepfake, an AI-generated dupe designed to deceive or entertain. Now, researchers have trained AI to look for visual inconsistencies similar to humans in order to detect AI-generated fake videos.
