# Kling v2.6 Motion Control 视频生成

* Kling 动作控制模型（参考图 + 参考视频）
* 动作控制模型，通过统一入口 `/v1/videos/generations` 调用
* 支持 image / video 两种人物朝向，最大时长分别为 10s / 30s
* 视频生成为异步任务，提交后返回 task\_id

## 认证

<ParamField header="Authorization" type="string" required>
  所有接口均需要使用 Bearer Token 进行认证

  获取 API Key：

  访问 [API Key 管理页面](https://xcompute.us/keys) 获取您的 API Key

  使用时在请求头中添加：

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

## 请求参数

<ParamField body="model" type="string" required>
  视频生成模型名称：`kling-v3-motion-control` 或 `kling-v2-6-motion-control`
</ParamField>

<ParamField body="prompt" type="string">
  文本提示词，用于补充动作、镜头和风格要求

  可选但建议填写，描述越具体结果越稳定

  示例：`"人物按参考视频动作起舞，动作连贯，写实风格"`
</ParamField>

<ParamField body="image_url" type="string" required>
  参考图片 URL

  需为公网可访问链接
</ParamField>

<ParamField body="video_url" type="string" required>
  参考视频 URL

  需为公网可访问直链，建议 mp4/mov 且不超过 100MB

  <Warning>
    服务端会探测 `video_url` 实际时长，最短为 3 秒；上限由 `character_orientation` 决定
  </Warning>
</ParamField>

<ParamField body="keep_original_sound" type="string" default="yes">
  是否保留参考视频原音轨

  可选值：

  * `yes`：保留原音轨（默认）
  * `no`：不保留原音轨
</ParamField>

<ParamField body="character_orientation" type="string" required>
  人物朝向控制方式

  可选值：

  * `image`：以参考图人物朝向为主（参考视频时长需 `3~10s`）
  * `video`：以参考视频人物朝向为主（参考视频时长需 `3~30s`）
</ParamField>

<ParamField body="mode" type="string" required>
  生成模式

  可选值：

  * `std`：标准模式（速度和质量均衡）
  * `pro`：高质量模式（通常更耗时）
</ParamField>

<ParamField body="watermark_info" type="object">
  水印控制对象（可选）

  <Expandable title="watermark_info 字段">
    <ParamField body="enabled" type="boolean" default="false">
      是否添加水印

      * `true`：添加水印
      * `false`：不添加水印（默认）
    </ParamField>
  </Expandable>
</ParamField>

## 时长规则

| 参数条件                            | 允许的参考视频时长  |
| ------------------------------- | ---------- |
| `character_orientation = image` | `3s ~ 10s` |
| `character_orientation = video` | `3s ~ 30s` |

<Note>
  计费时长由服务端对 `video_url` 探测得到的真实时长决定，而非客户端估算值。
</Note>

## 响应

<ResponseField name="code" type="integer">
  响应状态码，成功时为 200
</ResponseField>

<ResponseField name="data" type="array">
  返回数据数组

  <Expandable title="数组元素">
    <ResponseField name="status" type="string">
      任务状态，初始提交时为 `submitted`
    </ResponseField>

    <ResponseField name="task_id" type="string">

  </Expandable>
</ResponseField>

## 使用场景

### 场景 1：image 朝向（10 秒内）

```json theme={null} theme={null}
{
  "model": "kling-v2-6-motion-control",
  "prompt": "保持人物朝向与参考图一致，完成转身和挥手动作",
  "image_url": "https://example.com/ref-image.png",

  "watermark_info": {"enabled": false}
}
```

### 场景 2：video 朝向（30 秒内）

```json theme={null} theme={null}
{
  "model": "kling-v2-6-motion-control",
  "prompt": "跟随参考视频的人物朝向和节奏，保持动作连贯",
  "image_url": "https://example.com/ref-image.png",
  "video_url": "https://example.com/ref-video-12s.mp4",
  "character_orientation": "video",
  "mode": "pro",
