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

PixVerse V4.5 Text To Video Fast
PixVerse V4.5 Text To Video Fast is the PixVerse V4.5 route for fast, turning the documented source inputs into a production-ready result while keeping the operation distinct from neighboring endpoints. V4.5 Fast is PixVerse's text-to-video AI model. Turn written scripts and prompts into professional-quality video clips with realistic motion, lighting, and scene composition. The workflow is designed for creators who need the model’s specific transformation to remain visible in the request, so the source, intended change, and finished artifact can be reviewed as one coherent creative decision.
In practical use, this route exposes seed, style, prompt, resolution, aspect_ratio to shape the exact deliverable. Those controls let a team preserve the important source constraints, state subject behavior or material treatment precisely, choose supported timing or output characteristics, and reproduce successful settings across alternate takes. The result fits an iterative pipeline: establish the core brief, compare controlled variations, then pass the selected asset into editorial, design, localization, visualization, or publishing work.
Highlights
- Route-specific creation. Use this exact route for fast with its documented input contract. This capability belongs to the exact
pixverse/v4.5/text-to-video/fastworkflow. - Directed motion. Translate the request into subject movement and camera behavior while maintaining temporal continuity.
- Format control. Choose the documented duration and resolution options for the target placement.
- Repeatable variation. Use seed and route controls to explore alternates without changing the core shot brief.
Pricing
| Configuration | Price |
|---|---|
| 360p or 540p | $0.300000 |
| 720p | $0.400000 |
| 1080p | $0.800000 |
When to Use
| Scenario | Why it fits |
|---|---|
| Exact workflow fit | Choose this route when the required deliverable is fast, rather than a related route with different source media. |
| Directed creative iteration | Use it when subject, motion, material, speech, framing, or finish should be expressed explicitly and compared across controlled variants. |
| Existing-asset continuity | Use it when supplied images, video, audio, references, or styles must remain the anchor for the generated result. |
| Repeatable production | Use it when successful inputs need to be saved and rerun across a campaign, asset set, localization pass, or batch. |
| Pipeline handoff | Use it when the returned artifact will move into editorial, compositing, visualization, review, storage, or publishing. |
Prompt Guide
Start with the source or subject, then describe the intended transformation, movement or behavior, camera and composition, and the desired finish. Keep media URLs reachable, use only fields documented for this exact route, and change one major control at a time when comparing results. For source-led tasks, describe what should change as well as what must remain recognizable.
