---

### 五、 Prompt 编写规范

1. 编写逻辑：需包含完整的场景描述 + 角色设定 + 分镜设计 + 镜头语言，强化双人对话互动逻辑。

2. 触发词说明：无需特定触发词。

3. 参考提示词示例（古风）：

[场景] 古风仙侠，云端仙境，粉紫霞光与翻涌云海交织，暖金日光穿透云层洒落，仙气缥缈朦胧，氛围梦幻唯美，尽显东方仙侠的空灵意境。

[角色] 女子：古典发髻挽起，点缀银质花叶发饰；身着天蓝色轻纱广袖裙，裙身绣有鎏金莲花纹样，肩带与袖摆薄如蝉翼，手持琉璃净瓶，瓶中盛有清透仙水，宛如瑶池临凡的仙子。男子：墨色长发束起，银质发冠点缀；身着月白色广袖仙袍，袖口与衣摆绣有银线云纹，手持白玉柄拂尘，尘丝垂落随风轻晃，仙风道骨，仿若天界执掌时序的仙君。

分镜 1 (全景 3 秒) 俯拍全景。云海翻涌如浪，粉紫霞光铺满天际，暖金日光斜洒而下，两人并肩立于云端，衣袂随仙气轻扬，与云雾霞光融为一体，尽显仙境的辽阔与缥缈。

分镜 2 (中景 4 秒) 正面中景。镜头缓缓推近，女子微微侧身，指尖轻托琉璃净瓶，瓶中仙水泛着细碎微光，她抬眸望向身旁男子，眉眼含柔，轻声道：“仙君，今日凡间春汛已平，这净瓶仙水可滋养人间草木，唤回生机。”

分镜 3 (近景 3 秒) 侧拍近景。男子手持拂尘，目光落在女子手中的净瓶上，语气平和温润：“有劳仙子费心，人间得此仙泽，定能岁岁繁茂，不负春日。”

分镜 4 (特写 2 秒) 特写镜头。聚焦女子手中的琉璃净瓶，瓶身通透如冰，仙水在光下流转泛着莹光，裙身鎏金莲花纹样若隐若现，与瓶中微光相映，细节尽显东方仙意的精致。

分镜 5 (全景 4 秒) 拉远全景。镜头缓缓拉远，两位仙子的身影渐渐融入云海霞光之中，拂尘尘丝与净瓶微光在云雾中闪烁，最终化作天际一点流光，只留缥缈仙踪于天地间。

### 六、 效果说明与局限性

1. 优势风格：在古风、现代、3D 动漫类双人对话场景中表现最佳。

2. 已知限制：受限于 LTX-2.3 底模性能，极其复杂的双人肢体互动（如缠绕、打斗）可能出现形变。

3. 运动幅度：建议以对话和微动作为主，大动态动作的连贯性仍有提升空间。
