HappyHorse 1.1 视频生成

• 阿里云百炼 HappyHorse 1.1 视频生成模型（统一入口，单模型自动路由）
• 根据传入字段自动路由：T2V（仅 prompt）/ I2V（first_frame_image）/ R2V（image_urls）
• 支持 720P/1080P 分辨率，3-15 秒任意整数时长
• 仅按分辨率 × 视频秒数计费，与具体能力无关

认证

模式路由

happyhorse-1.1 是文生视频 / 图生视频 / 参考图生视频的统一入口，后端根据传入参数自动判断模式，所有模式按统一规则计费（仅按分辨率 × 秒）：

路由优先级（从高到低）：first_frame_image > image_urls > 仅 prompt。

字段互斥规则：两个媒体字段（first_frame_image / image_urls）互斥。同时传两个互斥字段会返回 400 mixed_media_not_allowed。

请求参数

响应

使用场景

场景 1：文生视频 T2V（最简请求）

{
  "model": "happyhorse-1.1",
  "prompt": "一个小女孩走在路上，电影感画面"
}

场景 2：文生视频 T2V（完整参数）

{
  "model": "happyhorse-1.1",
  "prompt": "夕阳下的海边公路，慢镜头推进，电影感画面",
  "resolution": "1080P",
  "size": "16:9",
  "duration": 8,
  "seed": 42
}

场景 3：图生视频 I2V（first_frame_image）

{
  "model": "happyhorse-1.1",
  "prompt": "让图片中的场景动起来",
  "first_frame_image": "https://example.com/first_frame.png",
  "resolution": "1080P",
  "duration": 5
}

场景 4：参考图生视频 R2V（多张参考图）

{
  "model": "happyhorse-1.1",
  "prompt": "图1中的主角在图2的场景中奔跑，随后拿起图3中的道具。画面保持3D卡通风格，动作流畅。",
  "image_urls": [
    "https://example.com/img_01.jpg",
    "https://example.com/img_02.png",
    "https://example.com/img_03.jpeg"
  ],
  "resolution": "1080P",
  "size": "16:9",
  "duration": 5
}

场景 5：720P 节省额度

{
  "model": "happyhorse-1.1",
  "prompt": "海浪拍打沙滩，日落时分",
  "resolution": "720P",
  "size": "16:9",
  "duration": 5
}

模式选择建议

使用建议

1. 统一入口逻辑：根据传入字段自动路由模式，注意两个媒体字段（first_frame_image / image_urls）互斥
2. size 仅 T2V/R2V 生效：I2V 模式下 size 会被忽略，输出宽高比由输入媒体决定
3. 时长建议：5\~10 秒为甜点区，过短动作不连贯，过长上游耗时显著增加
4. 首帧图片质量：清晰、构图明确、主体居中，能显著提升 I2V 效果
5. prompt 写作：描述运动 / 镜头 / 氛围（如 "缓慢推近、电影感、暖色调"），比单纯描述静态场景效果更好
