  "title": "鞋子侧移镜头：鞋底落地，检查轮廓变化",
  "description": "用原创首帧练习小幅横向运镜，把合理的视角变化与鞋底滑走、鞋头拉长区分开，逐项检查鞋头、后跟和鞋底。",
  "goal": "完成一个鞋子静止、摄影机小幅侧移的单镜头。配套插画是原创规划输入，本方法未通过实际生成H3视频验证。",
  "preparation": [
    "使用配套三分之二侧面鞋图，或鞋头、后跟与鞋底完整可见的自有授权图片。练习鞋不带商标，避免将品牌复刻混入轮廓检查。",
    "画面保留深度不同的两个固定背景特征；示意图提供后方竖板边和小方块，用于区别机位侧移与鞋子横滑。",
    "移动范围只需多露出一点后跟；真实鞋子的隐藏内侧不能由一张侧面图准确提供。",
    "保存起始图，记下鞋头尖、后跟领口顶部、鞋底与台面的接缝三个轮廓点。对照时要允许视角投影发生合理变化。"

  "prompt": "以上传图作为起始构图。一只奶油色跑鞋始终放在台面上，鞋底持续接触台面。摄影机保持相同高度，缓慢向右横移一小段，只多露出一点后跟。背景竖板和小方块随视角产生自然位置关系变化。视角变化时，鞋头长度、后跟领口、鞋带数量与鞋底厚度保持连贯。鞋子自身静止，不在转台上旋转。横移结束后稳定停留。柔和固定棚灯，一个连续镜头，不新增商标或文字。",

      "body": "三处采样对照鞋头到后跟的比例和领口形状。允许正常投影变化；鞋头伸长、鞋底裂开或鞋带多一排均不通过，下一轮只减小移动范围。"
