Google Flow turns a text prompt into a video clip, complete with sound, and then lets you build that clip into a scene with the same characters in it. It is Google’s AI filmmaking tool, built around its Veo video model, and it solves the problem that defined early AI video: striking single shots that could not hold together as a story. This guide explains how Flow works and how to make your first videos.
The short version is that Flow is a workspace, not just a generator. You create characters and looks as reusable ingredients, generate clips with Veo, control the camera, bridge shots with start and end frames, stretch clips longer, and sequence everything on a timeline. The model underneath is Veo 3.1, which generates video and synchronised audio together, so dialogue, sound effects and ambient noise arrive in the same file as the picture.
What Google Flow Is
Flow launched on May 20, 2025, as Google’s AI filmmaking tool, custom-designed for its most advanced models: Veo for video, Imagen for images, and Gemini for language. It is the evolution of VideoFX, an earlier Google Labs experiment, and it was built with and for creatives, from independent filmmakers to people making their first short.
Google describes Flow as the only AI filmmaking tool custom-designed for its own models, and the design shows it. Gemini models sit behind the prompting, so you can describe your vision in everyday language rather than learning a prompt syntax. Imagen generates the images you use as ingredients. Veo generates the moving picture and the sound. One workspace holds all three, plus the timeline that joins the results.
At launch, Flow was available to subscribers of the Google AI Pro and Google AI Ultra plans in the US, with more countries coming soon. In its first five months, Google says more than 275 million videos were generated in Flow, which is a useful measure of how fast the tool went from experiment to everyday creative instrument.
Start With a Clip: Text to Video
The simplest way into Flow is text to video: describe a scene, and Veo generates a clip from it. A good prompt covers the subject, what is happening, the setting, the camera, and the mood. Google’s own example style is concrete: who is in the shot, what they are doing, where they are, and how the camera moves.
Camera controls are the difference between a clip and a shot. Flow gives you direct control over camera motion, angles and perspectives, so you can ask for a slow push-in on a face, a wide aerial over a landscape, or a handheld tracking shot following a cyclist, and get that movement rather than a static frame with motion inside it.
Behind the prompt box, Gemini models make prompting intuitive, turning an everyday description into something the video model can execute. Gemini is the same model family behind AI features across Google’s products, including the AI features in Chrome, and in Flow its job is to close the gap between what you mean and what the model renders.
It helps to write prompts in five parts, in this order: subject, action, setting, camera, and mood. “A street vendor flips noodles at a night market, steam rising, neon signs reflected in wet pavement, slow push-in, warm and busy” gives the model a person, a motion, a place, a camera move and a feeling. Leave one part out and the model invents it, which is fine for exploration and bad for continuity.
Plan a Short Film in Flow
A workable Flow project follows the same order every time. Start with the story in one sentence: who the film is about, what changes, and where it ends. That sentence decides your ingredients, because everything you generate afterwards has to serve it.
Next, build the ingredients before generating any video. Create the protagonist, the key locations and the visual style as reference images, and check that they look consistent with each other. A character designed after the first scene exists will never quite match it.
Then generate one test clip per scene, not the whole film. A test clip tells you whether the ingredients hold, whether the camera move works, and whether the sound fits. Keep the winners, regenerate the failures, and only then extend the keepers and join them in Scenebuilder.
Finally, use Frames to Video for the transitions between scenes. A film made only of text-to-video clips feels like a slideshow of nice shots; a film whose scenes are bridged by start-and-end frames feels directed. The transitions are where the project stops looking generated and starts looking made.
Keep Characters Consistent With Ingredients
The feature that makes Flow a filmmaking tool rather than a clip toy is Ingredients to Video. Ingredients are reference images for the characters, objects and style of your project: a protagonist’s face, a costume, a prop, a location’s look. You can bring your own assets, or make ingredients with Imagen’s text-to-image capabilities inside Flow.
Once you have created a subject or a scene, you can integrate those same ingredients into different clips and scenes with consistency. That is the whole point: the same character, in the same clothes, in the same visual style, across dozens of separate shots, instead of a new stranger every time you generate.
With Veo 3.1, Ingredients to Video also gained audio, so a scene built from your ingredients arrives with sound as well as picture. The practical tip is to invest in good ingredients first: a clear, consistent reference image does more for continuity than any amount of prompt rewriting later.
Control the Shot With Frames to Video
Frames to Video is Flow’s answer to the transition problem. You provide a starting image and an ending image, and Flow generates a seamless video that bridges the two, synthesising the motion, lighting and camera movement needed to get from the first frame to the last.
Use it when you already know how a shot should begin and end. A product turning from front to back, a character turning from profile to face-on, a landscape shifting from dawn to dusk, or a stylised morph between two scenes: all of these are start-and-end problems, and anchoring both ends gives you far more control than a blind text generation.
Frames to Video also gained native audio with Veo 3.1, so the bridge between your two frames carries sound as well. It is the feature to reach for whenever a cut feels abrupt: instead of accepting the jump, give Flow both sides of it and let it film the middle.
Make It Longer Than 8 Seconds
A single Veo generation is a short clip: Google’s own benchmark notes describe Veo videos as 8 seconds long. That is plenty for a shot, and far too little for a scene. Flow’s answer has two parts: Extend and Scenebuilder.
Extend takes a clip and continues the action from it. Each extension is generated based on the final second of the previous clip, which is what keeps the background and characters continuous. Google says extended videos can last for a minute or more, making Extend most useful for longer establishing shots and sustained action.
Scenebuilder is where clips become a film. It lets you seamlessly edit and extend existing shots, revealing more of the action or transitioning to what happens next with continuous motion and consistent characters. You can trim, reorder and join clips into a sequence, and preview the scene as a whole rather than as isolated generations.
The workflow that works is to generate short, then extend deliberately. Get a strong 8-second shot first, extend the ones that deserve more time, and assemble in Scenebuilder, rather than trying to generate a long scene in one pass.
Sound Arrives With the Picture
Veo 3 added native audio generation, and Veo 3.1 extended it across Flow. That means dialogue, ambient sound and sound effects are generated together with the video frames, in a single pass, instead of being dubbed on afterwards. A character’s lines arrive lip-synced, and the room tone matches the room on screen.
The practical consequence is that you should prompt sound the way you prompt picture. Name the dialogue, the ambient noise and the music in the same prompt as the shot: a market’s chatter, rain on a window, a door closing off-screen. Google’s DeepMind page stresses that Veo’s audio is synchronised with the video content, which is what separates a clip with sound from a clip with a soundtrack pasted on.
With Veo 3.1, audio reached the features that previously ran silent: Ingredients to Video, Frames to Video and Extend all gained native audio. If you built a project before that update, its silent clips are the reason; regenerating them through the current features brings the sound with them.
When the sound is wrong, regenerate rather than patch. Because audio and video are generated together, a line delivered flat or a sound effect that does not fit usually means the whole take missed the prompt, and a new generation with a clearer sound description fixes both tracks at once. Treat sound as part of the shot, not as a layer added later.
Fix Shots Without Starting Over
Flow’s editing tools exist for the moment the first take is not the final one. With Insert, you can introduce new elements into a scene, from realistic details to fantastical creatures, and Flow handles complex details like shadows and scene lighting so the addition looks natural rather than pasted in.
Google also announced Remove, for taking objects or characters out of a scene while Flow reconstructs the background and surroundings as though they were never there. At the October 2025 announcement it was described as coming soon, so treat it as a roadmap feature rather than a tool you can rely on today.
Asset management ties the editing together: Flow lets you organise all your ingredients and prompts in one place, so a fix to one scene does not mean hunting through a scattered project. Keep ingredients named and organised, and revisions stay cheap.
Learn From Flow TV
Flow TV is Flow’s showcase, and it is the fastest way to get better at the tool. It is an ever-growing collection of clips, channels and content generated with Veo, and crucially, you can see the exact prompts and techniques used for clips you like.
Use it as a study tool, not just a gallery. When a clip achieves a look you want, read its prompt: how it described the camera, how it specified the sound, how it set the scene. Then adapt that structure to your own ingredients rather than copying the clip. Google built Flow TV as a practical way to learn styles, and that is how it repays the time.
Channels on Flow TV are worth following for the same reason. A creator whose work you admire is effectively publishing a course in prompt craft, one clip at a time, and the prompt attached to each clip shows you the decisions behind the result. Study the prompts of people working in your genre before you spend generations finding the same lessons by trial and error.
One caution: a prompt that worked for someone else’s ingredients will not reproduce their clip with yours. Prompts are half the recipe; the reference images are the other half. Treat Flow TV prompts as structure to borrow, not as spells to recite.
A Worked Example: One Scene, Four Tools
Take a simple scene: a street vendor at a night market, flipping noodles as rain starts. The ingredients come first: a portrait of the vendor, a reference for the market stall, and the visual style, warm neon against wet pavement. Generate them with Imagen or upload your own, and confirm they look like they belong together.
Next, generate the opening clip from text, using the vendor ingredient and a slow push-in, and prompt the sound in the same breath: sizzling woks, market chatter, rain beginning on canvas awnings. If the take works, extend it so the rain builds and the vendor looks up, letting the action run past the first clip.
Then bridge to the next scene with Frames to Video. Supply the last frame of the market shot and the first frame of the vendor walking home through wet streets, and let Flow film the walk between them. Finally, join both clips in Scenebuilder, trim the overlap, and watch the scene as a whole. Four tools, one continuous minute, and no point where the vendor becomes a different person.
What Flow Cannot Do Yet
First, the features are experimental and actively improving, in Google’s own words. Veo 3.1’s editing capabilities were introduced as new and being iterated on, so expect behaviour to change between projects, and do not build a deadline around a feature that may still be rough.
Second, length is still assembled, not generated. Even with Extend reaching a minute or more, a finished film is a Scenebuilder sequence of many clips, and every join is a place where continuity can slip. Plan your scenes as sequences from the start, and budget time for the joins.
Third, availability and limits vary by plan and region. Flow launched to Pro and Ultra subscribers in the US, and its features and limits have shifted as it has expanded. Check what your plan includes before planning a large project around a particular model or resolution.
Background
Flow began as VideoFX, became Google’s AI filmmaking tool in May 2025, and gained its current shape with Veo 3.1 in October 2025: audio across Ingredients, Frames and Extend, plus precise editing. DeepMind’s benchmarks rate Veo 3.1 ahead on preference, alignment and quality. Veo 3.1 is also available in the Gemini app, the Gemini API and Vertex AI, but Flow holds the full filmmaking toolset.
