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

PixVerse
PixVerse is the PixVerse route for lip synchronization, turning existing footage plus speech into a production-ready result while keeping the operation distinct from neighboring endpoints. Lipsync is PixVerse's video-to-video AI model. Transform, enhance, and edit video content using text prompts - from style changes to object manipulation and scene modification. 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 text, voice_id, audio_url, sync_mode, video_url, safety_tolerance 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
- Audio-led mouth timing. Synchronize facial motion in an existing video to a finished spoken recording.
- Built-in speech option. Supply text instead of audio and select a documented voice for a combined speech-and-lip-sync workflow.
- Existing-footage workflow. Preserve the supplied performance and framing while revising the spoken delivery.
- Dubbing-ready output. Create a synchronized clip that can move directly into review, localization, or social publishing.
Pricing
| Configuration | Price |
|---|---|
| Video processing | $0.040000 per second |
| Uploaded-audio workflow | No text-to-speech surcharge |
| Text-to-speech | $0.240000 per started 100 characters |
When to Use
| Scenario | Why it fits |
|---|---|
| Exact workflow fit | Choose this route when the required deliverable is lip synchronization, 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.
