提示词结构解析

这条提示词是一个完整的「分镜头脚本 + 提示词」复合体，结构非常清晰：

  • 时间码（timestamp）：每个镜头以 0:00–0:02 格式标注起始时间，控制视频节奏
  • 镜头类型（shot type）：如 Front phone-camera perspective、Medium close-up、Tracking shot 等，定义了拍摄视角
  • 动作描述（action）：描述主播和产品的具体动作，如 rotates the handbag slowly，opens the bag and places
  • 视觉特效（visual effects）：如 shopping notifications appear、LED-style sale graphics 增加电商氛围
  • 旁白对白（dialogue）：镜头中的人物台词，真实感强
  • 一致性约束：最后一行显式要求「Maintain the same host, same hairstyle...same lighting」确保跨镜头角色一致

制作步骤与实操指南

  1. 理解分镜结构：提示词采用了时间线叙事方式，每一帧都包含时间码、镜头描述、动作和对白。这是 AI 视频广告的标准格式。
  2. 角色一致性是关键：提示词末尾显式要求「Maintain the same host, same hairstyle, same makeup...」这是商业 AI 视频最重要的提示词技巧。
  3. 参数调优：可尝试调整镜头时长（如将 0:02 改为 0:03 延长产品展示）、或替换对白内容适配不同产品。
  4. 场景扩展：可以在此模板基础上替换产品描述（手袋→化妆品/电子产品）、调整环境设置和灯光氛围。
  5. 音效和氛围：提示词中包含了对音效（Upbeat Japanese city-pop instrumental）的描述，确保视频的整体感官一致性。

实操建议

  • 先用简短的 2-3 镜头测试提示词的有效性，确认角色一致性后再扩展完整分镜。
  • 每轮生成后检查角色外观是否一致，如果不一致可以调整描述词或增加参考特征。
  • 不同 AI 视频工具对提示词长度有不同限制，注意拆分长提示词。
  • 直播带货类提示词的关键是「信任感」——主播的表情、光线、产品展示方式都要自然真实。
