AIGC漫剧提示词工程：Prompt模板、风格关键词与负向提示词系统化方法

[主体描述] + [动作表情] + [场景背景] + [光照氛围] + [摄影风格] + [画质参数]

# SD WebUI / ComfyUI 权重语法（通用标准）
(keyword:1.3)    # 增强权重，数值范围0.1-1.5，超过1.5可能过拟合
(keyword:0.7)    # 降低权重，弱化该元素的影响
((keyword))      # 双括号约等于权重1.21倍增强
[keyword]        # 方括号约等于权重0.91倍降低
(((keyword)))    # 三括号约等于权重1.46倍增强

# Flux / Midjourney 风格权重
keyword::1.3     # Flux模型使用双冒号加数值
keyword:::0.5    # 三段权重分配

# 区域权重控制（Regional Prompter）
# 通过mask控制不同区域使用不同prompt
# 适合同一画面中多个角色各持特征的场景

Q1：同一角色在不同镜头中长相不一致怎么办？

A：这是AIGC漫剧中最常见的问题。解决方案有三个层级：第一，使用固定的角色Prompt模板，确保每个镜头的角色描述段完全一致，并对核心特征施加1.2-1.3的权重；第二，训练角色专属LoRA模型，用10-20张角色设定图训练，权重0.6-0.8，这是目前最可靠的方案；第三，使用IP-Adapter或Reference Only ControlNet，将首张满意出图作为面部参考，后续镜头自动对齐。建议三个方案组合使用，可将角色一致性提升至95%以上。

Q2：提示词应该用英文还是中文？

A：对于Stable Diffusion和Flux系列模型，强烈建议使用英文标签式提示词，因为这些模型的训练数据以英文为主，CLIP/T5文本编码器对英文的理解更准确。Midjourney v7对中文有一定支持但英文效果仍更优。如果使用国产模型（如通义万相、可图），则中文提示词效果更好。实际操作中，可以先用中文描述创意意图，再用AI翻译工具转换为结构化的英文标签，两者结合效率最高。

Q3：负向提示词越长越好吗？

A：不是。负向提示词过长会导致模型"无所适从"，反而降低画面质量。一般建议负向提示词控制在30-50个关键词以内，聚焦于最需要排除的问题。通用基础排除（质量、人体结构、风格污染）约20个关键词即可覆盖大部分场景。针对特定镜头的额外排除项应按需添加，用完即删。另外，过强的负向提示词可能导致画面发灰或细节丢失，需要与正向提示词平衡配置。

Q4：权重值设多高合适？有没有上限？

A：一般建议权重控制在0.5-1.5的范围内。1.0为默认值（不增强不减弱），1.1-1.3为温和增强（最常用），1.3-1.5为强力增强（谨慎使用）。超过1.5容易导致过拟合——画面出现色彩失真、元素堆叠、风格崩坏等问题。低于0.5则可能让该元素完全消失。多关键词同时施加高权重时，总权重叠加效应需要注意，建议单次Prompt中权重增强的关键词不超过5个，且每个不超过1.3。
