New AI research makes it easier to create fake footage of someone speaking

An aspect of artificial intelligence that's sometimes overlooked is just how good it is at creating fake audio and video that's difficult to distinguish from reality. The advent of Photoshop got us doubting our eyes, but what happens when we can't rely on our other senses? The latest example of AI's audiovisual magic comes from the University of Washington, where researchers have created a new tool that takes audio files, converts them into realistic mouth movements, and then grafts those movements onto existing video. The end-result is a video of someone saying something they didn't. It's a confusing process to understand by just reading about it, so take a look at the video below: You can see two side-by-side clips of Barack Obama.
