# MiniMax-H3-Context-IR 多模态提示词增强

> 视频生成

提交异步提示词增强任务。`input.content` 中必须且只能包含一个非空文本项；模型会根据其余媒体项及 `role` 自动选择处理模式。

支持的输入组合：
- 文生视频提示词：仅包含一个 `text` 项。
- 图生视频提示词：`text` 加一张首帧或尾帧图片，或者加首帧和尾帧各一张。
- 多模态参考提示词：`text` 加参考图片、参考视频和参考音频的组合。

图生视频与多模态参考互斥，不能在同一次请求中混用帧图片和参考媒体。

**输入媒体限制**（请求体总大小 ≤ 64 MB，大文件请用公网 URL，勿用 Base64）：

| 长宽比（宽/高） | [0.4, 2.5] |
| 数量 | 首帧 ≤ 1、尾帧 ≤ 1、参考图 ≤ 9 |

| 个数 | ≤ 3 |
| 单段时长 | [2, 15] s；总时长 ≤ 15 s |
| 宽高范围 | [256, 5760] px |
| 长宽比（宽/高） | [0.4, 2.5] |
