+For MiniMax-H3, local files and Base64 data URIs are preflight-checked against the documented limits: image 30 MB, reference video 50 MB, reference audio 15 MB, and total JSON request body 64 MB. The API validates dimensions, aspect ratio, duration, frame rate, and codecs for all media.
+
+`--region` is an existing global CLI option, not an H3 parameter. Normal video generation does not need it; the CLI uses the saved or automatically detected region. H3 defaults to 2K, 5 seconds, and 16:9 for text-to-video.

+MiniMax-H3 会在发送前检查本地文件和 Base64 数据：图片不超过 30 MB、参考视频不超过 50 MB、参考音频不超过 15 MB、JSON 请求体总计不超过 64 MB。所有素材的尺寸、宽高比、时长、帧率和编码格式仍由 API 服务端校验。
+
+`--region` 是 CLI 原有的全局选项，不是 H3 参数。正常生成视频无需填写，CLI 会使用已保存或自动识别的区域。H3 默认使用 2K、5 秒，文生视频默认比例为 16:9。
