Authorization: Bearer YOUR_API_KEY
请求体
application/json
图片 URL 数组，1–2 张
图片数量与行为：
| 图片数量 | 行为 | 角色 |
|---|---|---|
| 1 张 | 首帧图生视频 | 自动设为 first_frame |
| 2 张 | 首尾帧图生视频 | 第 1 张 → first_frame，第 2 张 → last_frame |
图片要求：
- 支持格式：
.jpeg、.png、.webp - 宽高比（宽/高）：
0.4~2.5 - 宽高像素：
300~6000px - 单张大小：不超过
30MB - 请求体总大小不超过
64MB - 传入首尾帧时，两张图片可相同。宽高比不一致时以首帧为准，尾帧会自动裁剪适配
- 图像 URL 需要服务器能直接访问
素材地址： 支持公网可访问的 HTTP(S) URL，也支持当前上游账号可访问的 asset:// 素材 ID。
Required array length:
1 - 2 elements示例:
["https://example.com/first-frame.jpg"]
