Google’s new VideoPoet AI video generation model looks incredible

Simply yesterday, I requested if Google would ever get an AI product launch proper on the primary attempt. Think about that requested and answered — not less than, going by the appears to be like of its newest analysis.

This week, Google confirmed off VideoPoet, a brand new giant language mannequin (LLM) designed for quite a lot of video technology 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 high performers in video technology. These video fashions usually begin with a pretrained picture mannequin, resembling Steady Diffusion, that produces high-fidelity photos 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 distinct kind of AI mannequin based mostly on the transformer structure, usually used for textual content and code technology, resembling in ChatGPT, Claude 2, or Llama 2. However as a substitute of coaching it to supply textual content and code, the Google Analysis group educated 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 a few of the state-of-the-art consumer-facing video technology fashions resembling Runway and Pika, the previous a Google funding.

Longer, larger high quality clips with extra constant movement

Greater than this, the Google Analysis group notes that their LLM video generator method may very well permit for longer, larger high quality clips, eliminating a few of 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 only a few frames.

“One of many present bottlenecks in video technology is within the capacity to supply coherent giant motions,” two of the group members, Dan Kondratyuk and David Ross, wrote in a Google Research blog post saying the work. “In lots of instances, 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 bounce, together with simulating completely different digicam motions, completely different visible and aesthetic types, even producing new audio to match a given video clip. It additionally handles a variety of inputs together with textual content, photos, and movies to function prompts.

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

In truth, viewers surveyed by the Google Analysis group most popular it. The researchers confirmed video clips generated by VideoPoet to an unspecified variety of “human raters,” in addition to clips generated by video technology diffusion fashions Supply-1, VideoCrafter, and Phenaki, displaying 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 popular 41–54% of examples from VideoPoet for extra attention-grabbing movement than 11–21% for different fashions.” You’ll be able to see the outcomes displayed in a bar chart format under as properly.

Constructed for vertical video

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

Trying forward, Google Analysis envisions increasing VideoPoet’s capabilities to assist “any-to-any” technology duties, resembling text-to-audio and audio-to-video, additional pushing the boundaries of what’s doable in video and audio technology.

There’s just one downside I see with VideoPoet proper now: it’s not at present accessible for public utilization. We’ve reached out to Google for extra data on when it would develop into accessible and can replace after 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 in the marketplace.
