How to identify AI-generated videos online
By Cecily Mauran
Sorry to disappoint, but if you’re looking for a quick list of foolproof ways for detecting AI-generated videos, you’re not going to find it here. Gone are the days of AI Will Smith grotesquely eating spaghetti. Yes, there are some tells, but AI video makers are getting better all the time, and the latest tools can create convincing, photorealistic videos with a few clicks.
Right now, AI-generated videos are still a relatively nascent modality compared to AI-generated text, images, and audio, because getting all the details right is a challenge that requires a lot of high-quality data. “But there’s no fundamental obstacle to getting higher quality data,” only labor-intensive work, said Siwei Lyu, a professor of computer science and engineering at University at Buffalo SUNY...
To identify face swaps, look for flaws or artifacts around the boundaries of the face. “You typically see artifacts when the head moves obliquely to camera,” said digital forensics expert and UC Berkeley Professor of Computer Science Hany Farid. As for the arms and hands, “If the hand moves, or something occludes the face, [the image] will glitch a little bit,” Farid continued. And watch the arms and body for natural movements. “If all you’re seeing is this,” — on our Zoom call, Farid keeps his arms stiff and by his sides — “and the person’s not moving at all, it's fake...”
Hany Farid is a professor in the Department of Electrical Engineering & Computer Sciences and the School of Information at UC Berkeley.
