How fake or how real is the growing stream of artificial intelligence (AI)-produced video? Turns out, there's a quantitative measure for that -- or, almost. Humans still need to decide, based on their human perception, if a video is good or not. Also: New Meta Ray-Ban AI features roll out, making the smart glasses even more tempting Mark Zuckerberg, owner of Meta Platforms, announced on Friday a new AI model called Movie Gen that can generate HD videos (1080p resolution) from a text prompt.
The firm says these videos are more "realistic" on average than videos generated by competing technology (such as OpenAI's Sora text-to-video model). It can also generate synced audio, tailor the video to show a person's face, and then edit the video automatically with just a text prompt, such as, "dress the penguins in Victorian outfits" to cloak on-screen penguins. Also: OpenAI unveils text-to-video model and the results are astonishing.
See for yourself In the accompanying paper, "Movie Gen: A Cast of Media Foundation Models," Meta AI researchers describe how they had humans rate the realism of the AI-generated videos: Realness: This measures which of the videos being compared most closely resembles a real video. For fantastical prompts that are out of the training set distribution (e.g.
, depicting fantasy creatures or surreal scenes), we define realness as mimicking a clip from a movie following a realistic art-style. We additionally ask the evaluators to select a reason behind their c.
