学习目标LEARNING OBJECTIVES

学完你能用扩展编辑（Extend Edit）一键把选中的编辑点滚到播放头位置，快速做出 J-cut / L-cut。

概念说明CONCEPTS

扩展编辑（Extend Edit）把选中的编辑点一次性移动到播放头处——快捷键 E，省掉拖拽对齐，是做拆分编辑（Split Edit）的主力操作。

  • 播放头即目标：先把播放头停在新位置，按 E，选中的编辑点立刻滚过去。
  • 可以多轨一起：每条轨道各选一个编辑点，一次 E 全部到位，音画错位一刀完成。
  • 模式决定行为：选择模式下是缩放（resize），修剪编辑模式下变波纹（ripple），后续片段跟着移动（见 修剪编辑模式）。
  • 为 J-cut / L-cut 而生：只选音频编辑点扩展，声音先进画面后切；只选视频则反之（见 拆分编辑）。

操作步骤STEPS

  1. 选中要移动的编辑点，可多轨各选一个
  2. 把播放头移到编辑点的新位置播放头定位到扩展目标位置
  3. 按 E，或从 Trim 菜单选 Extend Edit
  4. 检查编辑点已滚到播放头处，回放确认衔接编辑点已扩展到播放头位置

练习PRACTICE

  1. 在一段对话里把下一段的音频编辑点扩展到播放头，做一个声音先行的 J-cut。
  2. 同时选中视频和音频编辑点，一次 E 把切点整体后移一秒。

常见问题FAQ

按了 E 编辑点没动？

先确认选中的是编辑点而不是整个片段，且播放头不在编辑点原位置上。从 Trim 菜单点 Extend Edit 效果相同。

扩展编辑和滚动编辑有什么区别？

扩展编辑是"跳到播放头"的滚动：一步到位，适合已知目标位置；滚动编辑 是手动拖，适合边拖边看。

为什么扩展到一半就停了？

素材手柄用完了。编辑点最多移到片段媒体的首尾边界，想再长只能换更长的素材。

Learning Objectives学习目标

After this card you can use Extend Edit to roll a selected edit point straight to the playhead with one keystroke — the fast road to J-cuts and L-cuts.

Concepts概念说明

Extend Edit moves every selected edit point to the playhead in one shot — press E and skip the drag-and-align; it's the workhorse behind split edits.

  • The playhead is the target: park the playhead at the new position, press E, and the selected edit point rolls right over.
  • Multiple tracks at once: select one edit point per track and a single E lands them all — picture and sound offset in one move.
  • Mode decides behavior: in Selection mode it resizes; in Trim Edit mode it ripples, carrying later clips along (see Trim Edit Mode).
  • Born for J-cuts and L-cuts: extend only the audio edit point and the sound leads the picture; extend only the video for the reverse (see Split Edit).

Steps操作步骤

  1. Select the edit point(s) to move — one per track if you like
  2. Move the playhead to the edit point's new positionThe playhead marks the extend target
  3. Press E, or choose Extend Edit from the Trim menu
  4. Check that the edit point rolled to the playhead, then play back the joinThe edit point has extended to the playhead

Practice练习

  1. In a dialogue scene, extend the next clip's audio edit point to the playhead for a sound-first J-cut.
  2. Select both the video and audio edit points and move the whole cut one second later with a single E.

FAQ常见问题

Pressed E and nothing moved?

First confirm you selected an edit point, not a whole clip, and that the playhead isn't already sitting on it. Choosing Extend Edit from the Trim menu does the same thing.

How is Extend Edit different from a roll edit?

Extend Edit is a "jump to the playhead" roll: one step, best when you know the target. Roll Edit is a manual drag, best when you want to watch as you drag.

Why did my extend stop halfway?

The handles ran out. An edit point can travel no further than the clip's media boundaries — for more length you need longer source material.
