Veo 3 is Google's video generation model, focused on creating dynamic visuals, character dialogue, and scene audio in a single creation process. It is suitable for advertising clips, product demonstrations, and short narrative scenes with clearly defined shot design. On this platform, veo3 supports text-based creation and image-driven creation, allowing you to organize visuals with a first frame or first and last frames, and retrieve video results through asynchronous tasks.
Clarify capacity, inputs and outputs, and calling methods before selecting a model.
The native specifications describe Veo 3's audio-visual generation capabilities; aspect ratios, image controls, and result retrieval methods correspond to this platform's invocation endpoints.
Learn what veo3 can bring to your work.
Veo 3 does more than generate silent visuals; it can incorporate character speech, lip movements, and ambient sound effects into a scene. When creating a coffee shop conversation or product explanation, you can specify in the prompt who speaks, what they say, and the background sounds, making sound part of the visual narrative rather than leaving it solely for post-production.
When you have existing visual assets, use an image to define the starting point of the scene, then use text to describe character actions, object movement, and camera changes. One image is suitable for animating product photos or illustrations; two images can be used for first-and-last-frame creation, allowing you to establish the opening and closing compositions before designing the motion in between.
Text-based creation is suitable for starting with scene descriptions, while image-based creation suits tasks with existing compositions. After completion, you can obtain the video link and video ID, and continue to retrieve a 1080p version. Asynchronous tasks and callbacks make it easy to integrate the generation workflow into a content workspace, without requiring users to wait for the same request to finish.
Start with specific tasks to find where the model can make an impact.
Enter product selling points, character actions, short lines, and scene atmosphere to create advertising shots with people speaking. For example, have a store clerk introduce a new product, and specify the customer's response and in-store ambient sounds. The deliverable is audiovisual clips for selection and editing, suitable for validating the advertising message first before adding brand subtitles and packaging.
Enter a product image and motion requirements to create showcase clips with a slowly advancing camera, a rotating subject, or changing backgrounds. If opening and closing designs already exist, you can submit first-and-last-frame images to guide the scene from its display state to its final state, then use the generated assets for product introductions or social media videos.
Break a script into clear short scenes, describing the characters, space, actions, and dialogue section by section to generate storyboards or service training scenarios. For example, create interaction shots such as ordering at a counter or handling inquiries. After delivery, edit them in script order and verify whether the dialogue and actions meet the teaching objectives, rather than treating them directly as a complete course.
Choose based on task complexity, input materials, and expected results.
veo3 belongs to Quality mode and is suitable when the focus is on shot performance and audiovisual expression for final assets. veo3-fast is positioned more toward speed and rapid iteration; when you need to explore multiple advertising concepts or repeatedly adjust prompts, consider Fast first. They are different versions, and the speed positioning should not be understood as a fixed completion time.
When you only have text, a single starting image, or a set of first and last frames, veo3's creation method already covers these needs. If the task requires combining people, clothing, and product elements from multiple images into the same scene, consider veo31-fast-ingredients; if 4K output is explicitly required, consider veo31, which supports this option.

Answers to common questions about using veo3.
veo3 is Quality mode, suitable for creating assets where shot quality matters; veo3-fast is geared more toward rapid iteration, suitable for exploring ideas and testing prompts. When choosing, first consider the task stage: prioritize Fast for concept experiments, and consider the standard version for final shots. Do not assume the same time difference exists every time.
Set action to image2video and submit image links through image_urls. One image is used for first-frame creation, while two images are used for first-and-last-frame creation. The prompt should describe the action and camera changes from the starting point to the endpoint, rather than treating the two images as a collection of assets that can be freely blended.
Veo 3 has native joint audio-video generation capabilities and can create character dialogue, lip synchronization, and scene sound effects. It is recommended to clearly specify the speaking characters, lines, and background sounds in the prompt, then listen and check the result. Automatic prompt translation is a text-processing feature and is not equivalent to video dialogue dubbing or language conversion.
You can select resolution=1080p, or use action=get1080p on an already generated video. The latter method requires submitting the video ID from the result as video_id, not task_id. veo3 does not support 4K; if you need higher output clarity, consider veo31.
Set async=true to obtain task_id first, then query the task result; you can also set callback_url to receive completion notifications. Successful results include the video link, video ID, and status. Applications should display videos based on the completed status and distinguish between task IDs and video IDs, which are used for tracking tasks and obtaining high-definition versions respectively.
