H3 电影感双镜有声短片（纯文本） · 4 秒快测H3 cinematic two-shot scene with native audio (text-only) · 4s quick test

纯文本生成有声短片：第一镜建立场景与人物，第二镜在指定时间点转折。提示词按 MiniMax H3 的三段式结构组织——画面、环境声、配乐分开写，避免模型把音乐当成环境音处理。【4 秒快测版】内容与原版一致，压到 4 秒用于试参数、试素材、试机器，不用于出成片。

Text-only two-shot cinematic scene with native audio: shot one establishes, shot two turns on a named timecode. [4s quick test] Same content as the full-length version, cut to 4 seconds for checking parameters, assets and hardware — not for final delivery.
