On Tuesday at Google I/O 2024, Google introduced Veo, a brand new AI video synthesis mannequin that may create HD movies from textual content, picture, or video prompts, much like OpenAI’s Sora. It will probably generate 1080p movies lasting over a minute and edit movies from written directions, but it surely has not but been launched for broad use.
Veo reportedly consists of the flexibility to edit present movies utilizing textual content instructions, preserve visible consistency throughout frames, and generate video sequences lasting as much as and past 60 seconds from a single immediate or a collection of prompts that kind a story. The corporate says it could generate detailed scenes and apply cinematic results equivalent to time-lapses, aerial photographs, and numerous visible kinds
Because the launch of DALL-E 2 in April 2022, we have seen a parade of latest picture synthesis and video synthesis fashions that purpose to permit anybody who can kind a written description to create an in depth picture or video. Whereas neither know-how has been absolutely refined, each AI picture and video turbines have been steadily rising extra succesful.
In February, we coated a preview of OpenAI’s Sora video generator, which many on the time believed to signify the perfect AI video synthesis the business might supply. It impressed Tyler Perry sufficient that he put his movie studio expansions on maintain. Nevertheless, thus far, OpenAI has not offered common entry to the instrument—as a substitute, they’ve restricted its use to a choose group of testers.
Now, Google’s Veo seems at first look to be able to video technology feats much like Sora. We now have not tried it ourselves, so we will solely go by the cherry-picked demonstration movies the corporate has offered on its web site. Which means anybody viewing them ought to take Google’s claims with an enormous grain of salt, as a result of the technology outcomes will not be typical.
Veo’s instance movies embody a cowboy driving a horse, a fast-tracking shot down a suburban road, kebabs roasting on a grill, a time-lapse of a sunflower opening, and extra. Conspicuously absent are any detailed depictions of people, which have traditionally been difficult to for AI picture and video fashions to generate with out apparent deformations.
Google says that Veo builds upon the corporate’s earlier video technology fashions, together with Generative Question Community (GQN), DVD-GAN, Imagen-Video, Phenaki, WALT, VideoPoet, and Lumiere. To reinforce high quality and effectivity, Veo’s coaching knowledge consists of extra detailed video captions, and it makes use of compressed “latent” video representations. To enhance Veo’s video technology high quality, Google included extra detailed captions for the movies used to coach Veo, permitting the AI to interpret prompts extra precisely.
Veo additionally appears notable in that it helps filmmaking instructions: “When given each an enter video and enhancing command, like including kayaks to an aerial shot of a shoreline, Veo can apply this command to the preliminary video and create a brand new, edited video,” the corporate says.
Whereas the demos appear spectacular at first look (particularly in comparison with Will Smith consuming spaghetti), Google acknowledges AI video technology is troublesome. “Sustaining visible consistency could be a problem for video technology fashions,” the corporate writes. “Characters, objects, and even complete scenes can flicker, bounce, or morph unexpectedly between frames, disrupting the viewing expertise.”
Google has tried to mitigate these drawbacks with “cutting-edge latent diffusion transformers,” which is mainly meaningless advertising discuss with out specifics. However the firm is assured sufficient within the mannequin that it’s working with actor Donald Glover and his studio, Gilga, to create an AI-generated demonstration movie that can debut quickly.
Initially, Veo might be accessible to chose creators via VideoFX, a brand new experimental instrument out there on Google’s AI Take a look at Kitchen web site, labs.google. Creators can be part of a waitlist for VideoFX to doubtlessly achieve entry to Veo’s options within the coming weeks. Google plans to combine a few of Veo’s capabilities into YouTube Shorts and different merchandise sooner or later.
There is not any phrase but about the place Google obtained the coaching knowledge for Veo (if we needed to guess, YouTube was doubtless concerned). However Google states that it’s taking a “accountable” strategy with Veo. In accordance with the corporate, “Movies created by Veo are watermarked utilizing SynthID, our cutting-edge instrument for watermarking and figuring out AI-generated content material, and handed via security filters and memorization checking processes that assist mitigate privateness, copyright, and bias dangers.”
