# Wan2.6 動画生成

> Generate high-quality videos using Alibaba Cloud Wan2.6 model — supports text-to-video, image-to-video and reference-video

* Alibaba Cloud Wanxiang video generation model
* Supports **three modes**: Text-to-Video, Image-to-Video, and Reference Video (r2v)
* Server automatically routes to the appropriate upstream model based on your request parameters
* Supports 720p/1080p resolution, 5/10/15 second duration
* Audio is always included in the generated output

<Warning>
  **Important Change**: For better performance and cost control, we no longer support passing base64 image data directly in `image_urls`. Please use the [Upload 画像API](../../uploads/images) first to upload images and get URLs, then call this endpoint.
</Warning>

## Routing Logic

The server automatically selects the upstream model based on what parameters you provide:

| パラメータ Provided                         | Upstream Mode         |
| -------------------------------------- | --------------------- |
| `metadata.reference_urls` (video URLs) | Reference Video (r2v) |
| `image_urls` (image)                   | Image-to-Video (i2v)  |
| `prompt` only                          | Text-to-Video (t2v)   |

## 認証

<ParamField header="Authorization" type="string" required>
  All endpoints require Bearer Token authentication

  Get your API Key from the [API Key Management Page](https://toapis.com/console/token)

  Add to request header:

  ```
  Authorization: Bearer YOUR_API_KEY
  ```
</ParamField>

## リクエストパラメータ

<ParamField body="model" type="string" required>
  Video generation model name, fixed as `wan2.6`
</ParamField>

<ParamField body="prompt" type="string" required>
  Video content description

  必須 for text-to-video mode; optional for image-to-video and reference video modes (describe expected motion or style)

  Example: `"A cute cat stretching in the sunshine"`
</ParamField>

<ParamField body="image_urls" type="string[]">
  Reference image URL array for image-to-video mode (only supports 1 image)

  **⚠️ URL format only (base64 no longer supported)**

  * Publicly accessible image URL (http\:// or https\://)
  * You can use the [Upload 画像API](../../uploads/images) to upload local images and get URLs

  Example: `["https://example.com/image.jpg"]`

  **Note:** Cannot be combined with `metadata.reference_urls`
</ParamField>

<ParamField body="aspect_ratio" type="string" default="16:9">
  Video aspect ratio (applies to text-to-video and reference video modes)

  Available values:

  * `16:9` - Landscape (default)
  * `9:16` - Portrait
  * `1:1` - Square
  * `4:3` - Landscape
  * `3:4` - Portrait

  Default: `16:9`

  **Note:** Not supported in image-to-video mode
</ParamField>

<ParamField body="resolution" type="string" default="1080p">
  Video resolution

  Available values:

  * `720p` - Standard definition
  * `1080p` - High definition (default)

  Default: `1080p`

  480p is not supported. Billed per second; different resolutions have different prices — refer to the model marketplace for details.
</ParamField>

<ParamField body="duration" type="integer" default="5">
  Video duration (seconds)

  Supported values: `5`, `10`, `15`

  Default: `5`
</ParamField>

<ParamField body="negative_prompt" type="string">
  Negative prompt — describe content you do not want in the video

  Example: `"blurry, low quality, deformed"`
</ParamField>

<ParamField body="seed" type="integer">
  Random seed for reproducibility

  Example: `12345`
</ParamField>

<ParamField body="prompt_extend" type="boolean" default="true">
  Auto-extend prompt

  When enabled, the system automatically optimizes and enriches your prompt. **Enabled by default** — set to `false` to disable.
</ParamField>

<ParamField body="audio" type="boolean">
  Include audio in the generated video

  Non-flash Wan2.6 models always include audio by default. Set to `true` to explicitly enable.
</ParamField>

<ParamField body="shot_type" type="string">
  Shot type (applies to text-to-video and reference video modes)

  Available values:

  * `single` - Single continuous shot
  * `multi` - Multi-shot (cinematic cuts)
</ParamField>

<ParamField body="watermark" type="boolean">
  Add an Alibaba Cloud watermark to the generated video
</ParamField>

<ParamField body="metadata" type="object">
  Extended parameters

  <Expandable title="Show metadata fields">
    <ParamField body="reference_urls" type="string[]">
      **Reference Video (r2v) mode** — array of reference video URLs

      When provided, the server routes to the reference video upstream model (wan2.6-r2v). The model uses these videos to guide generation of consistent characters or scenes.

      * Each entry must be a publicly accessible video URL (http\:// or https\://)
      * Up to several reference videos are supported

      Example: `["https://cdn.example.com/ref1.mp4"]`

      **Note:** Cannot be combined with `image_urls`
    </ParamField>
  </Expandable>
</ParamField>

## Resolution and Aspect Ratio Combinations

| Aspect Ratio | 説明                  | 720p Size | 1080p Size |
| ------------ | ------------------- | --------- | ---------- |
| 16:9         | Landscape (default) | 1280×720  | 1920×1080  |
| 9:16         | Portrait            | 720×1280  | 1080×1920  |

<Note>
  **Querying Task Results**

  Video generation is an asynchronous task. After submission, a `task_id` is returned. Use the [Get Video Task ステータス](../../tasks/video-status) interface to query generation progress and results.
