MiniMax-H3 视频生成

• 异步处理模式，返回任务 ID 用于后续查询
• 支持文生视频、图生视频（首帧 / 尾帧 / 首尾帧）、多模态参考生视频（参考图 + 参考视频 + 参考音频）
• 支持 2K / 768P 分辨率，时长 4 ~ 15 秒，带音轨
• 与 MiniMax-Hailuo-02 / MiniMax-Hailuo-2.3 共用统一提交与查询接口

认证

生成模式

MiniMax-H3 通过请求字段自动路由到对应模式，无需指定 mode 字段：

请求参数

通用字段

图生视频字段

要做首帧 / 尾帧图生视频，必须显式指定，不要依赖 image_urls 张数推断。

多模态参考字段

通用图片数组（可选写法）

宽高比规则

可用具体比例：21:9、16:9、4:3、1:1、3:4、9:16。

输入媒体限制

请求体总大小 ≤ 64 MB。大文件请使用公网 URL，不要使用 Base64。

图片

视频（仅多模态参考场景）

音频（仅多模态参考场景）

参数约束

以下约束违反时请求将被拒绝并返回 400（敏感内容可能返回 422），且 不产生计费：
