认证

Authorization string
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://openveer.com) 获取您的 API Key 使用时在请求头中添加: ``` Authorization: Bearer YOUR_API_KEY ```

请求参数

model string
视频生成模型名称,固定为 `wan2.7-videoedit`
video_urls string
" required> 待编辑的原始视频 URL 数组
警告
**只取第 1 个视频**
注意
**视频限制:** * 格式:mp4、mov * 时长:2~10s * 分辨率:宽度和高度范围为 \[240, 4096] 像素 * 宽高比:1:8 \~ 8:1 * 文件大小:不超过 100MB
prompt string
编辑指令,描述希望对视频做什么改变,最多 5000 字符
注意
不传时模型将进行默认的风格迁移
示例:`"将人物的服装改为红色礼服"`、`"将背景替换为雪山场景"`
negative_prompt string
反向提示词,描述不希望出现的内容,最多 500 字符
image_urls string
"> 参考图片 URL 数组,最多 4 张 用于指定目标风格或外观(如风格迁移的目标样式参考)
resolution string
输出视频分辨率 可选值: * `720P` - 标清 * `1080P` - 高清(默认)
duration integer
输出视频时长(秒) * `0`(默认):保留原视频完整时长 * `2-10` 的整数:从头截取指定时长
注意
当 `duration=0` 时,以输出视频实际时长计费 指定时长不能超过 `video_urls` 原始视频的时长
size string
输出画面宽高比 支持的格式: * `16:9` - 横版宽屏 * `9:16` - 竖版长屏 * `1:1` - 正方形 * `4:3` - 横版 * `3:4` - 竖版
注意
不传则与输入视频宽高比保持一致
prompt_extend boolean
是否开启 prompt 智能改写 对较短提示词效果提升明显,但会增加耗时 默认值:`true`
watermark boolean
是否在生成的视频上添加 "AI生成" 水印 * `true`:添加水印 * `false`:不添加水印(默认)
seed integer
种子整数,用于控制生成内容的随机性 取值范围:`≥0` 的整数
注意
* 相同的请求下,模型收到不同的 seed 值(如:不指定 seed 值),将生成不同的结果 * 相同的请求下,模型收到相同的 seed 值,会生成类似的结果,但不保证完全一致
metadata object
附加参数对象 音频处理方式: * `auto`(默认):AI 根据编辑后的视频内容自动重新生成匹配音频 * `origin`:强制保留原视频音频,适合有重要背景音/对话的视频

响应

code integer
响应状态码,成功时为 200
data array
返回数据数组 任务状态,初始提交时为 `submitted`

  "video_urls": ["https://cdn.example.com/original.mp4"],
  "image_urls": [
    "https://cdn.example.com/anime_style.jpg"
  ],
  "resolution": "1080P",
  "watermark": false
}

场景 3:保留原视频音频

适合有重要背景音或人物对话的视频:

{
  "model": "wan2.7-videoedit",
  "video_urls": ["https://cdn.example.com/speech.mp4"],
  "prompt": "将背景替换为山间小路",
  "metadata": { "audio_setting": "origin" }
}

场景 4:完整参数

{
  "model": "wan2.7-videoedit",
  "prompt": "将人物的服装改为红色礼服",
  "negative_prompt": "模糊、失真",
  "video_urls": ["https://cdn.example.com/original.mp4"],
  "image_urls": ["https://cdn.example.com/reference.jpg"],
  "resolution": "1080P",
  "duration": 0,
  "size": "16:9",
  "prompt_extend": true,
  "watermark": false,
  "seed": 888,
  "metadata": {
    "audio_setting": "origin"
  }
}

音频处理说明

audio_setting 说明 适用场景
auto(默认) AI 根据编辑后的视频内容重新生成匹配音频 视觉风格大幅改变,希望音频同步更新
origin 强制保留原视频音轨 有重要背景音乐、人物对话的视频
注意
**查询任务结果** 视频生成为异步任务,提交后会返回 `task_id`。使用 [获取任务状态](/cn/api-reference/tasks/status) 接口查询生成进度和结果。
