Wan2.7 视频生成

• 阿里云万相 2.7 视频生成模型（统一入口）
• 根据传参自动路由：文生视频 / 图生视频（首帧、首尾帧、视频续写）
• 支持 720P/1080P 分辨率，2-15 秒时长
• 支持自定义音频（文生模式作背景音乐，图生模式作驱动音频）

模式路由

wan2.7 是文生视频和图生视频的统一入口，后端根据传入参数自动判断模式，两种模式计费完全一致：

请求参数

响应

使用场景

场景 1：文生视频（最简请求）

{
  "model": "wan2.7",
  "prompt": "夕阳下的海边公路，慢镜头推进，电影感画面"
}

场景 2：文生视频（完整参数）

{
  "model": "wan2.7",
  "prompt": "一只猫咪在草地上追逐蝴蝶，阳光明媚，慢动作",
  "negative_prompt": "模糊、变形、低质量",
  "resolution": "1080P",
  "duration": 8,
  "size": "16:9",
  "audio_url": "https://cdn.example.com/bgm.mp3",
  "prompt_extend": true,
  "watermark": false,
  "seed": 42
}

场景 3：首帧生视频

{
  "model": "wan2.7",
  "prompt": "人物缓缓站起身，向镜头走来",
  "image_urls": ["https://cdn.example.com/person.jpg"],
  "resolution": "1080P",
  "duration": 8
}

场景 4：首尾帧生视频

{
  "model": "wan2.7",
  "prompt": "镜头从海边缓慢移向山顶",
  "image_urls": [
    "https://cdn.example.com/beach.jpg",
    "https://cdn.example.com/mountain.jpg"
  ],
  "resolution": "1080P",
  "duration": 10
}

传 2 张时：第 1 张为首帧，第 2 张为尾帧。也可用 image_with_roles 精确指定。

场景 5：视频续写

{
  "model": "wan2.7",
  "prompt": "继续向前走，镜头跟随",
  "video_urls": ["https://cdn.example.com/clip.mp4"],
  "resolution": "1080P",
  "duration": 8
}

场景 6：图片 + 驱动音频

{
  "model": "wan2.7",
  "prompt": "人物随音乐节奏运动",
  "image_urls": ["https://cdn.example.com/dancer.jpg"],
  "audio_url": "https://cdn.example.com/beat.mp3",
  "resolution": "1080P",
  "duration": 8
}
