Close-up: The fabric of her dress catches the streetlight's glow, revealing a subtle silk sheen and the intricate stitching at the hem. Her black jacket’s subtle texture is visible – a fine wool perhaps, with a matte finish. The overall mood is one of quiet confidence and mystery, a vibrant woman navigating a bustling, nocturnal landscape. High resolution 4k.",

Wan 2.2 VACE Fun Outpainting
Wan 2.2 VACE Fun Outpainting is the Wan 2.2 workflow for canvas-extending video generation. It models visual appearance and time together so the route’s written direction, source imagery, speech, masks, or structural conditions influence one coherent result rather than a collection of disconnected frames or a generic endpoint response.
Choose this exact route when the available assets and deliverable specifically call for canvas-extending video generation. Identify every subject and source, state the desired action or transformation, then describe camera behavior, pacing, environment, lighting, atmosphere, and preservation requirements; local schema fields handle resolution, duration, seed, and delivery separately from the creative brief.
Highlights
- 2.2 Temporal outpainting. Creates new scene content beyond the original frame boundaries.
- 2.2 Perspective continuation. Extends geometry, horizon, and environment into the wider canvas.
- 2.2 Cross-frame edge consistency. Keeps generated border content stable through motion.
- 2.2 Composition-aware expansion. Reframes the action while preserving the source clip’s central intent.
Pricing
| Resolution | Price per generated second |
|---|---|
| Auto | $0.050 |
| 240p | $0.050 |
| 360p | $0.050 |
| 480p | $0.050 |
| 720p | $0.100 |
When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The project needs this exact video outpainting workflow | The intended task belongs to a different media route |
| Available source media matches every required field | Required assets or usage rights are unavailable |
| The brief can define subject, action, camera, and style | Output must be deterministic at frame or pixel level |
| Supported duration, resolution, and framing fit delivery | Final placement requires unsupported specifications |
| An asynchronous generation job fits production | A live or frame-synchronous response is mandatory |
Prompt Guide
Describe the result as a shot or design brief: identify subjects and references, state the action or transformation, specify environment and composition, then add camera behavior, lighting, pacing, style, sound, and preservation constraints where relevant. Use exact reference identifiers exposed by the local schema.
