人走路看起来是最好做的视频，结果是 AI 视频里崩得最频繁的一种。两个复合错误：相机跟的节奏不对，主体不是冲到镜头里就是越掉越远；脚和地面没接触，鞋像在冰上滑。解法是显式锁四件事：主体走速、相机走速（和主体匹配）、脚步落地（“每一步干净落地”）、焦段。下面这 10 个模板把这套配方分别套到 10 种场景，全部跑 5-8 秒。
一个好视频 Prompt 通常包含什么
行走人物镜头必须含 5 层，节奏和脚步落地不能省：
- 镜头 / 焦段：走镜适合长焦 —
85mm portrait、105mm telephoto、50mm prime，环境拍才用35mm - 光线状态：单一光态，和场景配 —
golden-hour low sun、overcast soft diffuse、neon practical magenta、single overhead studio softbox、cool blue dusk - 镜头运动（点名、慢、可控）：
slow tracking forward at matched walking pace、static medium shot subject walks in then out、slow dolly back at matched pace - 配色：固定一对命名色 —
warm cream and dust gold、desaturated teal and crimson、cool grey and warm amber、pastel cream and pale green - 主体收紧：一个人，一个节奏，一个视线方向。每一步要踩稳。5-8 秒，不要第二拍。

- 相机走速和主体不匹配 — 人物要么贴脸要么越走越远
- 一个镜头里既要转身又要笑又要看镜头 — 选一个视线、一个表情
- 没写脚步落地 — 鞋子在地上滑，瞬间出戏
- 拍人物走用广角 — 24mm 把脸压变形；85mm、105mm 才是正解
- 超过 8 秒 — 步态循环过了 8 秒会跑偏
下一步怎么改得更好
- 显式写
each footstep lands cleanly with visible shoe contact— 这一行就能把”鞋子滑地”压掉大半 - 节奏用人类语言写：
calm steady pace、brisk confident pace、unhurried meandering pace— 比slow准确得多 - 服装细节写死（具体颜色、剪裁）— 模糊服装跨帧会变
- 想要末尾一个回眸，写
at the very end she pauses and glances once, no body turn— 一个明确收边的动作 - 做组合拍：同一套服装与配色，分别拍迎面、并行、背影三个，剪成三联
常见问答 (FAQ)
Q: 为什么我的人物看起来像在飘？
A: 基本就是漏了脚步落地。加 each footstep lands cleanly with visible shoe contact 和 weight in each step。
Q: 相机和主体走速对不上，怎么办？
A: 镜头运动直接写 tracking backward at matched walking pace（背影就写 forward at matched pace）。写明”匹配”模型就能锁住节奏。
Q: 高跟鞋走起来很别扭，怎么办？
A: 高跟接触角难渲是已知短板。要么换平底，要么加 audible heel clack on each step — 模型会按”干脆落地”去画。
Q: 人物老是瞟镜头，怎么压？
A: 显式写 eyes forward, no glance at camera, no head turn。模型对人像默认会让她看你。
Q: 行走人物镜头比例怎么选？
A: 16:9 通用且容错；9:16 适合走秀和全身时尚走；2.39:1 宽银幕做编辑感迎面走最稳（前提是模型支持）。
