## Definition
|
||
|
||
首尾针动画是通过AI自动补齐首尾帧之间中间动作的技术，实现平滑过渡效果。
|
||
|
||
## Mechanism
|
||
|
||
1. 确定起始帧和结束帧
|
||
2. AI分析首尾帧的差异
|
||
3. 自动生成中间过渡帧
|
||
4. 输出流畅视频
|
||
|
||
## Tools
|
||
|
||
- 海螺AI
|
||
- KAI
|
||
- 其他AI动效工具
|
||
|
||
## Connection to Fixed-Camera Video
|
||
|
||
固定机位视频天然适合首尾针动画，因为：
|
||
- 背景固定，减少AI生成负担
|
||
- 只需关注主体变化
|
||
- 更容易保持一致性
