Google’s new VideoPoet AI video generation model looks incredible

Simply yesterday, I asked if Google would ever get an AI product launch proper on the primary strive. Take into account that requested and answered — no less than, going by the seems of its newest analysis.

This week, Google confirmed off VideoPoet, a brand new massive language mannequin (LLM) designed for quite a lot of video era duties from a group of 31 researchers at Google Analysis.

The truth that the Google Analysis group constructed an LLM for these duties is notable in-and-of-itself. As they write of their pre-review research paper: “Most current fashions make use of diffusion-based strategies which might be usually thought of the present prime performers in video era. These video fashions sometimes begin with a pretrained picture mannequin, equivalent to Steady Diffusion, that produces high-fidelity pictures for particular person frames, after which fine-tune the mannequin to enhance temporal consistency throughout video frames.”

Against this, as a substitute of utilizing a diffusion mannequin based mostly on the favored (and controversial) Steady Diffusion open supply picture/video producing AI, the Google Analysis group determined to make use of an LLM, a special kind of AI mannequin based mostly on the transformer structure, sometimes used for textual content and code era, equivalent to in ChatGPT, Claude 2, or Llama 2. However as a substitute of coaching it to provide textual content and code, the Google Analysis group skilled it to generate movies.

Pre-training was key

They did this by closely “pre-training” the VideoPoet LLM on 270 million movies and greater than 1 billion text-and-image pairs from “the general public web and different sources,” and particularly, turning that information into textual content embeddings, visible tokens, and audio tokens, on which the AI mannequin was “conditioned.”

The outcomes are fairly jaw-dropping, even compared to among the state-of-the-art consumer-facing video era fashions equivalent to Runway and Pika, the previous a Google investment.

Longer, increased high quality clips with extra constant movement

Greater than this, the Google Analysis group notes that their LLM video generator method may very well enable for longer, increased high quality clips, eliminating among the constraints and points with present diffusion-based video producing AIs, the place motion of topics within the video tends to interrupt down or flip glitchy after just some frames.

“One of many present bottlenecks in video era is within the capacity to provide coherent massive motions,” two of the group members, Dan Kondratyuk and David Ross, wrote in a Google Research blog post asserting the work. “In lots of circumstances, even the present main fashions both generate small movement or, when producing bigger motions, exhibit noticeable artifacts.”

However VideoPoet can generate bigger and extra constant movement throughout longer movies of 16 frames, based mostly on the examples posted by the researchers on-line. It additionally permits for a wider vary of capabilities proper from the leap, together with simulating totally different digital camera motions, totally different visible and aesthetic kinds, even producing new audio to match a given video clip. It additionally handles a variety of inputs together with textual content, pictures, and movies to function prompts.

Integrating all these video era capabilities inside a single LLM, VideoPoet eliminates the necessity for a number of, specialised elements, providing a seamless, all-in-one answer for video creation.

Actually, viewers surveyed by the Google Analysis group most well-liked it. The researchers confirmed video clips generated by VideoPoet to an unspecified variety of “human raters,” in addition to clips generated by video era diffusion fashions Supply-1, VideoCrafter, and Phenaki, exhibiting two clips at a time side-by-side. The human evaluators largely rated the VideoPoet clips as superior of their eyes.

As summarized within the Google Analysis weblog publish: “On common individuals chosen 24–35% of examples from VideoPoet as following prompts higher than a competing mannequin vs. 8–11% for competing fashions. Raters additionally most well-liked 41–54% of examples from VideoPoet for extra attention-grabbing movement than 11–21% for different fashions.” You possibly can see the outcomes displayed in a bar chart format beneath as nicely.

Constructed for vertical video

Google Analysis has tailor-made VideoPoet to provide movies in portrait orientation by default, or “vertical video” catering to the cell video market popularized by Snap and TikTok.

Wanting forward, Google Analysis envisions increasing VideoPoet’s capabilities to help “any-to-any” era duties, equivalent to text-to-audio and audio-to-video, additional pushing the boundaries of what’s doable in video and audio era.

There’s just one downside I see with VideoPoet proper now: it’s not at the moment out there for public utilization. We’ve reached out to Google for extra data on when it would grow to be out there and can replace once we hear again. However till then, we’ll have to attend eagerly for its arrival to see the way it actually compares to different instruments available on the market.
