API README

Wan 2.1 VACE Pose

Wan 2.1 VACE Pose is a Wan-family route for pose-controlled video generation. Wan’s video-focused generative architecture models appearance and time together, so supplied references, structural conditions, masks, speech, or written scene direction can influence a coherent sequence rather than a collection of unrelated frames. This exact route concentrates that architecture on its named production task.

Use the route when the available source material and final brief specifically require pose-controlled video generation. Identify every subject or condition, explain the intended action or transformation, and describe camera behavior, pacing, environment, lighting, atmosphere, and preservation constraints. This separates creative intent from the local duration, resolution, and delivery fields documented below.

Highlights

  • Pose-guided movement. Uses a pose sequence to direct body position and action over time.
  • Motion transfer. Carries articulated movement into a newly rendered subject or scene.
  • Temporal anatomy consistency. Maintains recognizable body structure across the controlled sequence.
  • Appearance freedom. Allows style, clothing, lighting, and environment to change around the pose condition.

When to Use

✅ Good fit❌ Consider alternatives
The project needs this exact named workflowThe intended task belongs to another media route
All required reference or control media is availableNecessary assets or rights are unavailable
The brief can state transformation and preservation goalsOutput must be deterministic at pixel or frame level
Supported duration, resolution, and format fit deliveryFinal placement requires unsupported specifications
An asynchronous generated result fits productionA live frame-synchronous response is mandatory

Prompt Guide

Identify the primary subject and every source or condition, state the intended transformation or action, then describe composition, camera or viewpoint, lighting, materials, pacing, atmosphere, and exact preservation requirements. Refer to multiple inputs in their schema order.

{
  "prompt": "A precisely directed composition with explicit subject, transformation, camera or viewpoint, lighting, material, and preservation requirements",
  "seed": 1,
  "video": "https://example.com/source.mp4",
  "resolution": "auto"
}

Questions

FAQ

How do I call Alibaba Wan 2.1 VACE Pose through SandBase?

Create a SandBase API key, then send requests with the model ID "alibaba/wan/2.1/vace/pose" to Unified Run API (/v1/run) at https://api.sandbase.ai. The request examples on this page show the exact payload.

Do I need a separate Alibaba account?

No. One SandBase API key and balance gives you access to Alibaba Wan 2.1 VACE Pose and the other models in the catalog; you do not need to sign up with Alibaba separately.
