卷动Roll Edit
剪辑操作 · Editing Actions
卷动是同时修剪相邻两个片段剪辑点的编辑方式：左侧片段的出点和右侧片段的入点一起移动，两个片段的总时长保持不变。
- 把鼠标放在剪辑点上，用卷动工具左右拖动。
- 左侧片段变长，右侧片段就变短，反之亦然。
- 适合微调剪辑点的位置，让动作衔接更顺畅。
A roll edit trims the cut point between two adjacent clips: the outgoing clip's out point and the incoming clip's in point move together, keeping the total duration unchanged.
- Hover over the cut and drag with the roll tool.
- If the left clip grows, the right clip shrinks, and vice versa.
- Great for fine-tuning a cut so the action flows better.
