Output Schema
| Field | Type | Description |
|---|---|---|
id | string | Unique identifier for the generation task |
status | string | Task status: pending, running, completed, failed, timeout |
model | string | Model used for the generation |
outputs | array | Array of output items |
outputs[].url | string | URL of the generated artifact |
outputs[].content_type | string | MIME type (e.g. image/png, video/mp4) |

Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read
outputsfrom the completed response

Veo 3
google/veo-3 creates a cinematic video from written scene direction, interpreting subject action, environment, camera language, lighting, and pacing. Veo 3 emphasizes prompt adherence, cinematic composition, and believable physical motion, allowing written film language to shape both what happens and how the camera observes it; it can also generate synchronized dialogue, effects, and ambience as part of the same sequence. This combination makes the model a practical choice when the creative outcome depends on those qualities rather than on a generic media conversion.
For production work with google/veo-3, the text-guided video generation workflow suits storyboards, campaign films, product moments, narrative shots, and visual concepts that need coherent motion rather than isolated animated frames. The result is most reliable when the source material and creative brief clearly describe the intended subject, progression, visual or sonic character, and the qualities that must remain unchanged.
Highlights
Cinematic prompt interpretation turns scene, action, lens, lighting, and camera language into moving imagery.
Physical motion coherence gives objects, characters, and environments more believable behavior.
Visual continuity maintains subjects and scene logic across the generated sequence.
Native audio generation coordinates dialogue, ambience, and sound effects with the visual action.
Pricing
| Duration | Audio off | Audio on |
|---|---|---|
| 4 seconds | $0.800 | $1.600 |
| 6 seconds | $1.200 | $2.400 |
| 8 seconds | $1.600 | $3.200 |
When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The model's named workflow matches the source material and intended output | A different input modality or model route is required |
| A managed asynchronous result is suitable for the production pipeline | A synchronous, interactive editor is essential |
| The documented controls cover the required duration, framing, or format | The project needs controls outside this endpoint's schema |
| Creative iteration benefits from a repeatable request structure | Exact deterministic pixels, frames, geometry, or samples are mandatory |
| A finished downloadable media asset is the desired deliverable | Editable source layers or a native project file are required |
Prompt Guide
For generation, state the intended result first, then add the subject or source treatment, progression, style, and delivery constraints. Keep one creative variable per phrase, use the documented field names for controls, and change one setting at a time when comparing results.
