AI can doctor videos to put words in the mouths of speakers

New Scientist 

A new system takes a still image of a person and an audio clip, and uses them to create a doctored video of the person speaking the audio. The results are still a little rough around the edges, but the software could soon make realistically fake videos only a single click away. At the moment, these systems focus on changing the shape of the mouth, but it's only a matter of time before they can also change facial expressions and posture, says Alex Champandard, co-founder of creative.ai, "Pretty soon we will have trouble distinguishing between real and fake video," says Champandard. Given enough time, experts can already create fake videos that are virtually indistinguishable from genuine ones.
