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
