--- title: "防穿帮" type: concept tags: [ai, prompt, video-generation] date: 2026-04-18 --- ## Definition AI 视频生成中的专业术语,指防止生成的视频中出现违和感(如物体穿模、飘动、不贴合等)。通过专用 Prompt 约束 AI 输出,减少视觉上的不自然感。 ## Problem Domain - 宠物衣服类视频最易穿帮:衣服不贴合身体、飘动、滑落 - 物体悬浮:产品未接触地面或表面 - 穿模:产品与宠物/场景边界模糊 - 尺寸变化:运动过程中产品大小改变 ## Solution 添加专用"防穿帮" Prompt: ``` The clothing must stay perfectly fitted to the pet's body. Rules: - the clothing follows body movement naturally - fabric moves subtly with motion - no slipping, floating, or clipping - no size change during movement ``` ## Related Concepts - [[模块化Prompt库]]:将 Prompt 拆分为可复用的独立模块 - [[图生视频]]:AI 将静态图像转化为动态视频的技术
