# --- 1. 运动控制 (Motion Control) ---
Parameters:
  duration_s: [时长，通常为 5s 或 8s]
  # 核心：使用箭头 "→" 定义运镜的序列
  movement: [动作A] → [动作B] → [动作C]
  # (例: FPV banked-orbit → low skim → steep climb)
  
  motion_curve: [物理速度曲线] ([备注：哪里加速，哪里减速])
  # (例: ease-in-out (subtle mid-shot speed ramp))
  
  stabilization: [防抖模式] (如 fpv-smooth / cinematic-smooth / handheld-raw)
  parallax: enabled, strength: [数值 0.1-1.0] ([备注：利用什么物体产生视差])

# --- 2. 画面细节控制 (Visual Consistency) ---
  depth_of_field: [景深设置], focus_target: [焦点始终跟随的主体]
  grain: [颗粒感强度] (需与原图一致)
  grade: [调色风格] (需与原图一致)

# --- 3. 分秒导演脚本 (Shot Notes) ---
# 最关键部分：按秒拆解画面内容，防止 AI 动作变形
  shot_notes: "
    0–1s: [起始动作] + [瞬间视觉冲击 (如掠过镜头)];
    1–Xs: [中间过渡动作] + [运镜轨迹描述 (如 80°倾斜盘旋)];
    X–Ys: [高潮动作] + [环境揭示 (如 拉升展现广阔平原)];
    Y–8s: [结尾落幅] + [最终构图保持 (如 驶向太阳)]."
