滑移Slip Edit
剪辑操作 · Editing Actions
滑移是保持片段在时间线上的位置不变，只改变其内容（入点与出点）的修剪方式。片段占用的位置不变，但里面显示的画面换成了前后其他部分，像"挪动取景框"。
- 在时间线上选中片段，用滑移工具拖动，片段的入点和出点会同步移动。
- 滑移不改变片段长度，只改变内容窗口。
- 适合素材够长、但当前位置正合适的情况。
A slip edit keeps a clip's position on the timeline fixed while changing its content (in and out points). The clip still occupies the same space, but the frames shown inside swap to earlier or later parts of the source, like moving a viewfinder.
- Select the clip in the timeline and drag with the slip tool; the in and out points move together.
- A slip edit changes the content window, not the clip's duration.
- Useful when the material is long enough and the position is already right.
