Veo 3 is Google's video generation model, focused on creating moving visuals, character dialogue, and scene audio within the same creation process. It is suited for ad clips, product demonstrations, and short narrative scenes with clearly designed shots. On this platform, veo3 supports text-based and image-driven creation, can organize visuals using a first frame or first and last frames, and retrieves video results through asynchronous tasks.
Submit requests to the public API at api.acedata.cloud using the documented parameters, then use the results in your application.
api.acedata.cloudveo3Input parameters and result formats vary by service. Use the public API for this model and follow its guide for generation, task retrieval and editing operations.
The native specifications describe Veo 3's audiovisual generation capabilities; aspect ratios, image control, and result retrieval methods correspond to this platform's access points.
Veo 3 does more than generate silent visuals: it can incorporate character speech, lip movements, and ambient sound effects into the scene. When creating a coffee shop conversation or product explanation, you can specify in the prompt who speaks, what they say, and the background audio, making sound part of the shot's narrative rather than something left for post-production.
When you have existing visual assets, use an image to establish the starting point of the scene, then describe character actions, object movement, and camera changes in text. One image is suitable for animating product photos or illustrations; two images are 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 a scene description, while image-based creation is suitable for tasks with existing compositions. Once complete, you can retrieve the video link and video ID, and continue to retrieve the 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.
Enter product selling points, character actions, short lines, and scene atmosphere to create advertisement shots featuring people speaking. For example, have a store clerk introduce a new product, and specify customer responses and ambient store sounds. The deliverables are audiovisual clips for selection and editing, suitable for validating the advertising message first before adding brand subtitles and packaging.
Enter product images and motion requirements to create showcase clips with a slowly advancing camera, a rotating subject, or changing backgrounds. If opening and ending designs already exist, you can submit first and last frame images to guide the visuals from the display state to the closing 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 check whether the dialogue and actions meet the learning objectives, rather than using them directly as a complete course.
veo3 is part of Quality mode, suitable when the focus is on shot quality and audiovisual expression for polished 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 that option.
For text only, use text2video; for image-driven creation, use image2video. One image in image_urls is the first frame, and two images are the first and last frames; describe the action that occurs in between.
Specify model=veo3 for /veo/videos, choose the action based on text or images, and fill in prompt. Start with aspect_ratio=16:9 and resolution=720p, then increase the output tier within this model's supported range.
After setting async=true, save the task_id and obtain the finished video through /veo/tasks or a callback; verify the visuals and audio, and save the video ID and downloaded file for subsequent production.
In front of a coffee shop counter, a clerk hands over a coffee and says, “Here is your coffee.” The cup makes a slight sound when set down, with a quiet indoor shop ambience in the background.
Verify the dialogue, lip movements, and cup-and-saucer sounds word by word; start with text2video, and do not interpret first and last frame inputs as multi-image asset fusion.
veo3 is the Quality mode, suitable for creating assets where shot performance matters; veo3-fast is geared more toward rapid iteration, making it 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 there is always the same difference in processing 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 ending point, 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 for 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 have higher requirements for output clarity, consider veo31.
Set async=true to first obtain task_id, then query the task result; you can also set callback_url to receive a completion notification. Successful results include a video link, video ID, and status. Applications should display the video based on the completion status and distinguish between the task ID and video ID, which are used for tracking tasks and obtaining the high-definition version respectively.
