滑移编辑Slip Edit
学习目标LEARNING OBJECTIVES
学完你能用滑移编辑（Slip Edit）在不动片段位置和时长的前提下，微调片段内部显示的素材内容。
概念说明CONCEPTS
滑移编辑（Slip Edit）让片段里的素材在自己的入出点"窗口"中平移——片段在时间线上的位置和时长都不变，换的只是窗口里显示的内容。
- 位置时长都不动：起点、长度、相邻片段全部原样，只有片段内部选用的素材范围变了。
- 修剪模式下进行：按
T进入修剪编辑模式（Trim Edit Mode），指针悬在片段中部时光标变成滑移图标。 - 四格预览护航：拖动时时间线查看器变四画面——上排是本片段的新入点、出点帧，下排是前后邻居的衔接帧。
- 白框即余量：片段两端延伸的白色轮廓就是素材余量（handles），轮廓到顶就再也滑不动。
操作步骤STEPS
- 按
T进入修剪编辑模式，时间线工具栏的模式按钮变红 - 把指针悬在目标片段的中部，确认光标变成滑移图标
- 按住片段左右拖动，对照四格预览选定新的内容范围
- 松开鼠标，从头播放该片段及前后衔接，检查动作是否连贯
练习PRACTICE
- 找一个素材有余量的片段，左右各滑移一次，说出四格预览上下两排各显示什么。
- 把两个相邻的动作镜头分别滑移到动作衔接的帧上，播放检查连贯性。
常见问题FAQ
滑移时片段为什么拖不动了？
素材余量用完了。滑移只能在原始素材的出入点范围内平移，白色轮廓到顶就没有可滑的空间。
滑移会改变时间线总时长吗？
不会。片段的位置和长度都不变，相邻片段也毫发无损——变的只是窗口里显示的内容。
滑移和滑动（Slide）怎么区分？
滑移换内容、不动位置；滑动挪位置、不动内容（见 滑动编辑）。名字相似，作用正好相反。

After this card you can use the Slip Edit to fine-tune which part of the source media a clip shows, without moving the clip or changing its duration.
Concepts概念说明
A Slip Edit shifts the source media inside a clip's own In-and-Out "window" — the clip keeps its position and duration on the timeline; only the content inside the window moves.
- Position and duration stay put: start point, length, and neighbors are all untouched — only the media range inside the clip changes.
- Done in Trim Edit mode: press
Tfor Trim Edit mode; hover the middle of a clip and the cursor turns into the slip icon. - Four-up preview: while you drag, the timeline viewer splits into four — the top pair shows your clip's new In and Out frames, the bottom pair shows the neighbors' joining frames.
- White outline = handles: the white outline extending past the clip's ends shows the available source handles; when it runs out, you can't slip any further.
Steps操作步骤
- Press
Tto enter Trim Edit mode — the mode button in the timeline toolbar turns red - Hover the middle of the target clip and confirm the cursor shows the slip icon
- Drag the clip left or right and use the four-up preview to pick the new content range
- Release, then play the clip and its surroundings to check the action flows
Practice练习
- Pick a clip with spare handles, slip it left and right once each, and say what each row of the four-up preview shows.
- Slip two adjacent action shots so the movement matches across the cut, then play to check continuity.
FAQ常见问题
Why won't my clip slip any further?
You've run out of source handles. Slipping can only move within the clip's original media range — when the white outline maxes out, there's nothing left.
Does slipping change the timeline's total duration?
No. The clip keeps its position and length, and the neighbors are untouched — only the content inside the window shifts.
How do I keep Slip and Slide straight?
Slip changes the content and keeps the position; Slide moves the position and keeps the content (see Slide Edit). Similar names, opposite effects.
