# Wan2.6 Flash 비디오 생성

> Generate videos using Alibaba Cloud Wan2.6 Flash model — faster image-to-video and reference video generation

> [!NOTE]
>
> **중국 본토 사용자 안내:** 중국 본토 사용자는 `https://toapis.cn` 를 API 엔드포인트(Base URL)로 사용해 주세요. 본 문서의 예시에서 `https://toapis.com` 을 `https://toapis.cn` 로 바꿔 주세요.

* Alibaba Cloud Wanxiang Flash (accelerated) video generation model
* Supports **two modes**: Image-to-Video and Reference Video (r2v)
* **Text-only generation is not supported** — you must provide an image or reference video URLs
* Supports 720p/1080p resolution; audio on/off option affects billing
* Faster generation speed — ideal for quick previews and iteration

> [!WARNING]
>
> **Image or reference video URL is required**: You must provide either `image_urls` (image-to-video) or `metadata.reference_urls` (reference video). Sending a prompt-only request will return an error.

## Routing Logic

The server automatically selects the upstream model based on your request parameters:

| 파라미터 Provided | Upstream Mode |
| - | - |
| `metadata.reference_urls` (video URLs) | Reference Video Flash (r2v-flash) |
| `image_urls` (image) | Image-to-Video Flash (i2v-flash) |
| `prompt` only | ❌ Returns error |

## 인증

**Authorization** `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
```

## 요청 파라미터

**model** `string` *required*

Video generation model name, fixed as `wan2.6-flash`

**image\_urls** `string[]`

Reference image URL array for image-to-video mode (only supports 1 image)

**필수 if `metadata.reference_urls` is not provided**

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

* Publicly accessible image URL (http\:// or https\://)
* You can use the [Upload 이미지 API](https://docs.toapis.com/docs/ko/api-reference/uploads/images.md) to upload local images and get URLs

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

**prompt** `string`

Video content description (optional)

Describe the expected motion or style to guide the model

Example: `"The person comes alive and smiles at the camera"`

**resolution** `string` (default: 1080p)

Video resolution

Available values:

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

Default: `1080p`

Different resolutions have different prices — refer to the model marketplace for details.

**duration** `integer` (default: 5)

Video duration (seconds)

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

Default: `5`

**audio** `boolean` (default: true)

Whether to generate audio in the video

* `true` - Generate video with audio (default)
* `false` - Generate silent video

**⚠️ Audio and silent videos are billed at different rates — choose accordingly**

Default: `true`

**watermark** `boolean`

Add an Alibaba Cloud watermark to the generated video

**metadata** `object`

Extended parameters

**Show metadata fields**

**reference\_urls** `string[]`

**Reference Video (r2v) mode** — array of reference video URLs

When provided, the server routes to the reference video Flash upstream model (wan2.6-r2v-flash). The model uses these videos to generate new content with consistent characters or scenes.

* Each entry must be a publicly accessible video URL (http\:// or https\://)

Example: `["https://cdn.example.com/ref-character.mp4"]`

**Note:** Cannot be combined with `image_urls`

## Audio vs Silent Pricing

| Mode | 720p Unit Price | 1080p Unit Price |
| - | - | - |
| With audio (`audio: true`) | ¥0.3 / second | ¥0.5 / second |
| Silent (`audio: false`) | ¥0.15 / second | ¥0.25 / second |

## 응답

**id** `string`

Unique task identifier for status queries

**object** `string`

Object type, always `generation.task`

**model** `string`

모델 name used

**status** `string`

Task status

* `queued` - Queued for processing
* `in_progress` - Processing
* `completed` - Successfully completed
* `failed` - Failed

**progress** `integer`

Task progress percentage (0-100)

**created\_at** `integer`

Task creation timestamp (Unix timestamp)

**metadata** `object`

Task metadata

## Usage Scenarios

### Scenario 1: Image-to-Video (with audio)

```json theme={null}
{
  "model": "wan2.6-flash",
  "image_urls": ["https://example.com/photo.jpg"],
  "prompt": "The person comes alive and smiles",
  "resolution": "1080p",
  "duration": 5,
  "audio": true
}
```

### Scenario 2: Image-to-Video (silent, lower cost)

```json theme={null}
{
  "model": "wan2.6-flash",
  "image_urls": ["https://example.com/photo.jpg"],
  "resolution": "720p",
  "duration": 5,
  "audio": false
}
```

### Scenario 3: Reference Video (r2v-flash)

```json theme={null}
{
  "model": "wan2.6-flash",
  "prompt": "The character is watching a movie on the couch",
  "metadata": {
    "reference_urls": ["https://cdn.example.com/ref-character.mp4"]
  },
  "resolution": "1080p",
  "duration": 5,
  "audio": true
}
```

> [!NOTE]
>
> **Querying Task Results**
>
> Video generation is an asynchronous task. After submission, a `task_id` is returned. Use the [Get Video Task 상태](https://docs.toapis.com/docs/ko/api-reference/tasks/video-status.md) interface to query generation progress and results.
