右侧 Playground 可直接调试：在 Authorization 填 Bearer sk-your-api-key，填好 model / input.media / parameters 后发起请求。提交成功返回 task_id，轮询与下载见下方说明。

本页是 wan2.7-videoedit（视频编辑）的创建接口：给一段视频 + 1–5 张参考图 + 自然语言编辑指令，对视频元素做换装、换背景等编辑。注意模型名 无连字符（videoedit）。完整异步流程见 Wan 概览。

• input.media 必须同时包含 video（被编辑的视频）与至少 1 张 reference_image（参考素材，≤5 张）。
• 模型名是 wan2.7-videoedit（无连字符），与 HappyHorse 的 happyhorse-1.0-video-edit（有连字符）不同，别写错。
• 创建请求走 /wan/api/v1/... 并带 X-DashScope-Async: enable，不要用 /v1/videos。

参数与媒体速查

参数	类型	必填	默认	说明
model	string	✓	—	固定 wan2.7-videoedit
input.prompt	string	✓	—	自然语言编辑指令
input.media	array	✓	—	见下方媒体表
parameters.resolution	string		720P	720P / 1080P
parameters.prompt_extend	bool		true	智能改写
parameters.watermark	bool		false	「AI 生成」水印

​

media[] 取值

type	必填	张数	说明
video	✓	1	被编辑的源视频
reference_image	✓	1–5	参考素材（新服装、新背景等）

视频编辑的输出时长跟随输入视频，不由 duration 决定，因此本能力通常不传 duration。

查询状态与下载视频

拿到 task_id 后，按以下三步查询状态并下载 mp4：

• 轮询 GET /v1/tasks/{task_id}（带 Authorization，查询不需要 X-DashScope-Async 头），每 5–10 秒一次（不要 < 3 秒），直到 status 变为 completed。
• 状态取值：submitted（排队）/ in_progress（生成中，progress 常停在 30% 属正常）/ completed（成功）/ failed（失败，看 error）。
• 下载：从响应的 result_url 直接 GET，不要带 Authorization 头（OSS 签名直链，带了反而 403）；result_url 默认 24 小时过期，务必尽快转存。

查询状态

curl "https://api.apiyi.com/v1/tasks/3b216861-6a5f-441d-a438-602ab2c0d103" \
  -H "Authorization: Bearer sk-your-api-key"

{
  "status": "completed",
  "progress": 100,
  "result_url": "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=...",
  "task_id": "3b216861-6a5f-441d-a438-602ab2c0d103"
}

# result_url 是 OSS 签名直链，下载时不要带 Authorization 头（带了反而 403）
curl -L -o out.mp4 "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=..."

TASK_ID="3b216861-6a5f-441d-a438-602ab2c0d103"
URL=$(curl -s "https://api.apiyi.com/v1/tasks/$TASK_ID" \
  -H "Authorization: Bearer sk-your-api-key" | jq -r '.result_url')
curl -L -o out.mp4 "$URL"   # 不带 Authorization

上面是「已有 task_id」的快捷查询/下载。完整轮询循环（含超时兜底）与 Python 客户端见 Wan 概览 · 异步调用流程。
