Introduction
Announced at Google I/O 2025 on May 21, 2025 , Flow, an AI video generation tool, is the latest technology jointly developed by Google DeepMind and Google Creative Lab. This innovative tool is realizing a future where high-quality visual content such as movies and promotional videos can be created without professional equipment or large production teams. While video production has traditionally been considered costly and time-consuming, the arrival of Flow has ushered in an era where anyone can easily generate cinematic videos.
In this article, we will explain Flow’s appeal and future potential in an easy-to-understand manner, while also explaining its basic mechanisms, pricing structure, and actual usage scenarios. If you’re interested in the fusion of AI and video production, please read to the end.
What is Flow?
Flow is a cutting-edge AI video generation tool developed by Google, an innovative service that automatically generates high-quality, cinematic-like videos simply by entering prompts. Flow works in conjunction with Google DeepMind’s video generation AI “Veo (Veo 3 ) ,” enabling the creation of videos with cinematic visual expression, realistic physical depictions, and natural camerawork.
What’s particularly noteworthy is the growing use of Flow among video creators, the advertising industry, and the entertainment industry. Flow also utilizes advanced AI technology to flexibly control everything from prompts to video composition, perspective changes, and the tone of the production. For example, even a simple input like “a futuristic car driving through the streets of Tokyo” can result in a video with a story, greatly expanding the scope of creativity.
One of the reasons it is popular with so many users is that it can be operated intuitively, even without specialized video editing skills.
Key features of Flow
Flow is a video creation and editing platform that combines cutting-edge AI technology from Google. By utilizing the video creation models “Veo3” and “Veo2,” the image creation model “Imagen,” and advanced editing functions, anyone can create professional-quality videos.
Here are four key features at the core of Flow:
Video generation using the latest model “Veo3”
Veo3 is the most advanced video generation AI model developed by Google and is featured as the core feature of Flow. Users can simply enter natural language prompts to generate high-resolution (1080p to 4K) videos up to one minute long in just a few minutes.
Veo3’s strengths lie in its high level of visual realism, including cinematic camerawork, physical consistency, consistent character movement, and spatial awareness. It also supports multilingual prompts, including Japanese, and its appeal lies in its ability to enable a wide range of visual expressions with just intuitive operation.
This has accelerated its use in a wide range of applications, including advertising videos, promotions , educational content, and short movies for social media.
Newly added function “Veo2” for video generation
Flow also supports Veo2, the predecessor to Veo3, and it is still useful for certain purposes. Veo2 is specialized for generating relatively short videos (around 8 seconds), and is suitable for creating animations and looping videos for posting on social media or for presentations.
The Veo2 is characterized by its real-time capabilities and its strength in simple compositions, as well as its light operation and fast response. Furthermore, compared to the Veo3, it is also suitable for slightly more abstract and artistic expressions, making it useful for experimental video production.
Flow is designed so that Veo2 and Veo3 can be used depending on the scene and purpose, allowing for flexible video production that suits the user’s goals.
Image material generation using “Imagen”
Flow not only supports video, but also integrates the image generation AI “Imagen,” a Google-developed image generation model that can generate high-quality still images from natural language input.
For example, if you enter the prompt “A woman standing on the beach at sunset,” a photorealistic, well-composed image will be instantly generated. These images can be used for a variety of purposes, such as video backgrounds, thumbnail images, presentation materials, and visuals for social media posts.
Imagen’s output precision is extremely high, with detailed textures and light representations that are precise, allowing you to create even more compelling visual content when combined with video.
Asset Management
Flow’s Asset Management feature is an advanced system that allows users to centrally manage the materials and files needed for video production. Users can organize and store images, audio, video clips, AI-generated materials, and more in folders for each of their video projects.
In addition, all materials used within Flow are automatically tagged and can be instantly accessed with AI-powered search assistance. Cloud-based, it also supports simultaneous work by multiple people, enabling efficient collaboration even in remote environments. This is an essential feature for streamlining material management, which can often be cumbersome, and achieving a smooth production flow.
Other video editing features
In addition to content creation using generative AI, Flow also offers basic video editing functions, such as splitting and merging scenes, adding background music and narration, applying filters, and adding subtitles, all of which are tasks typically performed with traditional video editing software, all in a browser-based environment.
With features such as AI automatically suggesting composition and presenting optimal editing templates based on the video theme, even beginners can use it with confidence. Flow’s unique strength is that by adding minor corrections and effects to the generated video, you can create a more polished video in a short amount of time.
Flow Pricing Plans
Flow is offered as Google’s AI video production tool, and to use it you basically need to subscribe to the “Google One AI Premium” or “Google AI Ultra” plans. These plans provide comprehensive access to Flow as well as advanced generative AI features such as Gemini Advanced (Gemini 1.5 Ultra), Imagen, and Veo3. Currently, there is no standalone billing plan for Flow, and it is offered as one of the features in these integrated plans.
Although the price range is a little high, the ability to use multiple AI generation tools across video, image, text, audio, etc. makes it a cost-effective option for professional creators and corporate users who want to actively utilize AI. The main pricing plans are summarized below.
| Monthly fee (tax included) | Available features | remarks | |
| Free Plan | free | Gemini 1.5 Pro (basic functions) | Veo and Imagen cannot be used |
| Google One AI Premium | ~$19.99 | Gemini 1.5 Ultra, Veo3, Imagen, etc. | 50% discount for the first 3 months |
| Google AI Ultra | ~$249.99 | Flow’s high-resolution and long-duration output features, Gemini Ultra extended API, Imagen HD, and more | Planned to be offered as a plan for higher-level professionals |
*Prices and features are based on information as of May 2025 and are subject to change.
In particular, “Google AI Ultra” is a plan for professional users who want to use Flow to create long, high-quality videos, and is expected to offer performance above Premium in terms of generation resources and output quality. It’s a good idea to consider choosing the plan that best suits your needs and production frequency.
3 Use Cases for Flow
Google’s AI video generation tool “Flow” is attracting attention as a video production environment that integrates generative AI such as Veo and Imagen. Now that it is available in Japan, many users are beginning to use it for video production.
Here, we will introduce three typical examples of how Flow is used, based on real reviews posted on sites such as X (formerly Twitter).
The combination of Flow and Veo 3
With many saying that “Finally, if you subscribe to Google AI Ultra, Flow will be available in Japan,” what has been attracting particular attention is its video generation in conjunction with Veo 3. For users who have been dissatisfied with US-based AI video tools, Flow, which is made by Google but can output high-quality video and sound, is an attractive option.
The Veo 3 in particular has been praised for its high expressiveness, its ability to reproduce camerawork and composition, and its natural spatial recognition.
However, to use Veo 3, you need to upgrade to the “Google AI Ultra” plan, which comes with a rather high monthly fee. In the future, it is expected that the price will be adjusted to be more affordable for more users, and that the feature will be made available as a standalone service.
Quickly create videos with Veo 2! Voices of delight at Flow’s domestic release
Flow, which was first available in the US, has now finally been made available to Google AI Pro users in Japan, with many creators trying it out as a new way of expression. In particular, video generation using Veo 2 is highly rated for its responsiveness, allowing high-quality videos to be completed in a short amount of time with just simple prompt input.
Users have posted videos of themselves trying it out on social media, praising its reproduction capabilities and speed of generation. The process from prompt to video is intuitive and fast, making it easy to use even for first-time AI video creators.
The generated video is of sufficient quality to be used for promotion on YouTube and social media, and a major advantage is that it can be used flexibly for both personal and commercial purposes.
Animate your own illustrations! Examples of using Flow from an artist’s perspective
One feature of Flow that is particularly popular among artists is the “generating animations using self-made illustrations.” Contributors upload their hand-drawn illustrations to Flow and, by simply giving simple instructions in English, successfully animate their drawings into smooth videos. They are impressed by the quality and praise it as “the best.”
The true value of Flow is that it allows anyone to visualize what they want to express through ingenious prompts using Gemini and DeepL. Advances in AI technology are opening up new creative opportunities for individual creators who previously didn’t have access to video production techniques and tools, and it’s expected that similar cases will increase in the future.
