Wan2.7-R2V 参考生视频

阿里云万相 2.7 参考生视频模型

基于一张或多张参考图片/视频，生成与其风格、人物、场景一致的新视频

支持角色一致性、风格迁移、多素材组合

支持参考音色（reference_voice）控制角色声音

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-r2v`

prompt string

视频内容描述，最多 5000 字符多图/多视频时用"图1"、"图2"、"视频1"等序号指代对应参考素材（按传入顺序）示例：`"图1中的人物来到图2的场景中，环顾四周"`

image_with_roles string

"> 带角色的图片数组，与 `video_urls` 至少传其一每个对象字段： * `url` (string)：图片 URL * `role` (string)：图片角色 * `reference_image` - 参考图（默认） * `first_frame` - 指定首帧（传入后 `size` 参数无效，宽高比以首帧图片为准） * `reference_voice` (string，可选)：该参考角色的音色样本音频 URL，用于控制生成视频中角色的声音示例： ```json [ { "url": "https://cdn.example.com/character.jpg", "role": "reference_image", "reference_voice": "https://cdn.example.com/voice_sample.mp3" }, { "url": "https://cdn.example.com/start.jpg", "role": "first_frame" } ] ```

video_urls string

"> 参考视频 URL 数组，最多 5 条（图片 + 视频总数 ≤ 5）与 `image_with_roles` 至少传其一

注意

**视频限制：** * 格式：mp4、mov * 时长：1～30s * 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

negative_prompt string

反向提示词，描述不希望出现的内容，最多 500 字符

resolution string

视频分辨率可选值： * `720P` - 标清 * `1080P` - 高清（默认）

duration integer

视频时长（秒）支持范围：`2` \~ `15` 秒默认值：`5`

警告

当参考素材中包含视频时：取值为 \[2, 10] 之间的整数。当参考素材中不包含视频时：取值为 \[2, 15] 之间的整数。

size string

画面宽高比支持的格式： * `16:9` - 横版宽屏（默认） * `9:16` - 竖版长屏 * `1:1` - 正方形 * `4:3` - 横版 * `3:4` - 竖版

警告

当通过 `image_with_roles` 传入 `first_frame` 时，此参数将被忽略，宽高比以首帧图片为准

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

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`

task_id string

任务唯一标识符

使用场景

场景 1：单参考图生成（最简）

{
  "model": "wan2.7-r2v",
  "prompt": "这个人走在街上，四周车水马龙",
  "image_with_roles": [
    { "url": "https://cdn.example.com/character.jpg", "role": "reference_image" }
  ]
}

场景 2：多参考图生成

{
  "model": "wan2.7-r2v",
  "prompt": "图1中的人物来到图2的场景中，学习图3的动作",
  "image_with_roles": [
    { "url": "https://cdn.example.com/person.jpg", "role": "reference_image" },
    { "url": "https://cdn.example.com/background.jpg", "role": "reference_image" },
    { "url": "https://cdn.example.com/pose.jpg", "role": "reference_image" }
  ],
  "resolution": "1080P",
  "duration": 8,
  "size": "16:9"
}

场景 3：基于参考视频生成

{
  "model": "wan2.7-r2v",
  "prompt": "以参考视频的风格，生成一段海边日落场景",
  "video_urls": ["https://cdn.example.com/style_reference.mp4"],
  "resolution": "720P",
  "duration": 8
}

场景 4：指定首帧 + 参考图

{
  "model": "wan2.7-r2v",
  "prompt": "参考人物从这个位置出发，向前走",
  "image_with_roles": [
    { "url": "https://cdn.example.com/character.jpg", "role": "reference_image" },
    { "url": "https://cdn.example.com/start.jpg", "role": "first_frame" }
  ],
  "resolution": "1080P",
  "duration": 8
}

场景 5：参考图 + 参考音色（精确方式）

{
  "model": "wan2.7-r2v",
  "prompt": "这个人走在街上，边走边说话",
  "image_with_roles": [
    {
      "url": "https://cdn.example.com/character.jpg",
      "role": "reference_image",
      "reference_voice": "https://cdn.example.com/voice_sample.mp3"
    }
  ],
  "resolution": "1080P",
  "duration": 10
}

图片指代规则

多张参考图时，在 prompt 中用数字序号指代：

第 1 张图 → "图1" 或 "第一张图"
第 1 个视频 → "视频1" 或 "第一个视频"

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。
