Google Flow is Google's hosted filmmaking tool for creating and arranging generated clips into scenes. Google introduced it around its Veo, Imagen, and Gemini models, with a browser interface for directing shots and working with visual references. You access Flow through a Google account and the access options available in your region; it does not provide open weights for running its hosted models locally. Google announcement, access guide

What can Google Flow do with clips, frames, and scenes?
Flow's launch announcement describes a workflow around characters, locations, objects, and other ingredients that can be reused while building a story. Its useful organizing idea is the shot: describe what happens, choose the assets that should guide the result, then decide how that clip fits the surrounding scene. Launch description
The video help guide documents generation from text, reference ingredients, and start or end frames. Frames give you a way to specify how a shot begins or ends, while the text describes the action between those points. Feature support depends on the selected model. Video creation, model feature matrix
Scenebuilder supports arranging clips, changing their order, trimming them, previewing a sequence, and downloading a scene. The editing guide also documents saving a video frame for use as an ingredient or frame in a later generation. These are concrete steps for carrying a visual idea across multiple shots. Scene-building documentation
Plan a short scene before generating. Write a sentence for the establishing shot, another for the main action, and another for the closing image. For each, specify the subject, camera position, motion, and details that should stay consistent. This is an editorial planning method for making the generated clips easier to assess together.
What access, model, and credit limits apply to Google Flow?
Flow access is conditional. Google's getting-started page requires verified adult age and a supported region, and describes different access entitlements for individual plans and qualifying Workspace accounts. Confirm the options shown to your account before building a project around a particular feature. Eligibility documentation
The feature matrix varies by model. Google says Flow will notify you if a feature is unsupported by the model you select. Consequently, a workflow built around reference images or clip extension should be checked against the model's current supported operations, rather than inferred from the general presence of a button in Flow. Model support guide
Credit consumption also depends on the model and operation. Google's credit help page says costs are per generation, and a single request can produce multiple generations. Check the output count together with the model before estimating the cost of a shot. Credit documentation
Preserving a character or location is a creative requirement to review, not a reason to skip inspection. Check clothing, object shape, lighting direction, and camera continuity between candidate clips. If a detail changes, decide whether to regenerate the clip, revise the scene, or use a different transition.
How do you create clips and assemble a scene in Google Flow?
Use the Flow web app for the workflow below, following the browser access link in Google's getting-started guide.
These are interface operations; the cited Flow guides do not supply a public Flow API or local CLI for reproducing this editing session. Access instructions
- Open Flow and create a project, or select an existing one.
- Choose video generation in the prompt box's model controls.
- Describe the subject, action, environment, lighting, and style.
- Select the available model, aspect ratio, output count, and generation length.
- Review the current credit cost and generate the clip. Creation steps, model and cost selection
An original starting brief could be: "A ceramic artist places a blue bowl on a wooden shelf. The camera remains at eye level and slowly moves closer. Soft morning light enters from the left. Keep the room quiet and the movement deliberate." Test a single clear action before adding multiple events to the shot.
For a frame-guided shot, choose the frames option and supply a start frame, an end frame, or both where supported. Describe what should happen between them. Google's help page documents these controls for transitions and image animation, while noting regional and image-type restrictions. Frame instructions
After generating, review the entire clip. Watch its beginning and ending, then check the movement in the middle. A still thumbnail is insufficient for evaluating whether an object changes shape or an action becomes unclear. Keep a note of the specific moment that needs revision so the next prompt has a concrete objective.
To assemble the scene, use the clip's More menu and Add to Scene. In Scenebuilder, arrange the clips and trim their starts or ends, then preview the sequence. Save useful frames from existing clips when they provide a reference for the next shot. Scene and frame workflow
Compare the sequence with the written plan. Does the establishing shot explain where the action occurs? Does the main shot communicate the action? Does the final shot create a usable ending? Remove unnecessary variants from the decision process by keeping only the candidates that satisfy a clear role in the scene.
For written shot briefs and image references, the PromptZone prompt library provides a place to begin organizing ideas. For context about the broader release landscape, use the AI model timeline.
How does Google Flow compare with ComfyUI?
Flow and ComfyUI provide different working environments. Flow's documentation focuses on generated assets and scene assembly in Google's service. ComfyUI's official repository describes node-based workflows, reusable subgraphs, local model execution, and API integration. Flow scene guide, ComfyUI repository
| Tool | Documented workflow | Practical choice |
|---|---|---|
| Google Flow | Hosted clips, reference frames, and Scenebuilder. Scene guide | Direct and assemble shots in one hosted interface |
| ComfyUI | Visual node graphs with local and hosted model options. Repository | Construct and manage the generation pipeline yourself |
The ComfyUI pillar covers that alternative in more detail. Compare them using the workflow you need to complete, including how references are supplied and how the final scene is assembled.
What else should you know before using Google Flow?
Does Google Flow run Stable Diffusion checkpoints?
Google documents Flow around its hosted generative models and their supported features. The cited Flow interface instructions do not document loading arbitrary Stable Diffusion checkpoints. Model guide
Can I use an existing image as a starting frame?
Google Flow supports adding start and end frames in compatible video generation modes. Check the selected model and regional restrictions before relying on a particular frame combination. Frame workflow
Does one request always cost one generation?
A Google Flow request can produce multiple generations, each charged at the selected model's per-generation rate. Check the output count and rate when budgeting your scene. Credit rules
Can I save a frame for the next shot?
In Google Flow, pause a clip and use Save frame to save that image to the project. You can then use it as an ingredient, start frame, or end frame for a later generation. Frame-saving instructions
