## 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
|
||
```
