学习目标LEARNING OBJECTIVES

学完你能进入动态修剪模式（Dynamic Trim Mode），边回放边用 J K L 把编辑点修到位。

概念说明CONCEPTS

动态修剪模式（Dynamic Trim Mode）让回放和修剪同时进行——选中编辑点后按 W 进入，用 JKL 在播放中实时推动编辑点，靠手感和节奏定剪点。

  • 先选点再进模式：选中一个或多个编辑点，按 W 进入；播放头变黄，提醒你现在只能修剪。
  • JKL 就是修剪键：J 向左修、L 向右修；按住 K 点按逐帧，组合键慢速，连按加速（见 JKL 搓擦）。
  • 修剪类型照选：按 U 循环切换出点/入点/滚动；滑移（Slip）与滑动（Slide）在工具栏图标上右键切换。
  • 空格即回放检查：修剪中按空格是绕编辑点回放（Play Around），循环检查刚修好的衔接。

操作步骤STEPS

  1. 在修剪编辑模式下选中要修的编辑点（见 修剪编辑模式）
  2. 按 W 进入动态修剪模式，播放头变黄黄色播放头表示已进入动态修剪模式
  3. 按 L 或 J 在回放中把编辑点推向理想位置，要逐帧就按住 K 点按
  4. 按空格绕编辑点回放，检查衔接是否自然空格键循环回放修剪结果
  5. 用 ↑ / ↓ 跳到下一个编辑点继续，全部修完按 W 退出

练习PRACTICE

  1. 选中三个连续编辑点，边听声音边各修一次，全部修完退出模式。
  2. 同一编辑点分别用实时 L 和逐帧 K+L 修，体会两种手感的差别。

常见问题FAQ

按了 JKL 时间线不播放了？

多半还停在动态修剪模式——看播放头是不是黄色的。按 W 退出，JKL 就恢复成播放控制。

动态修剪和普通拖拽修剪哪个好？

看场景。靠节奏和感觉的剪点（音乐、动作）用动态修剪边播边修；要精确帧数时用 精确修剪编辑器。

一次能修多个编辑点吗？

可以，进模式前选中多个编辑点，用 ↑ / ↓ 在它们之间跳转，逐个处理。

Learning Objectives学习目标

After this card you can enter Dynamic Trim Mode and use J K L to trim edit points during playback.

Concepts概念说明

Dynamic Trim Mode merges playback and trimming into one move — select an edit point, press W, and JKL pushes the edit point in real time, so you cut by feel and rhythm.

  • Select first, then enter: select one or more edit points and press W; the playhead turns yellow to remind you trimming is all you can do now.
  • JKL are your trim keys: J trims left, L trims right; hold K and tap for frame steps, combine keys for slow motion, double-tap for speed (see JKL Scrubbing).
  • Trim type still applies: press U to cycle Out point / In point / Roll; right-click the toolbar icon to switch between Slip and Slide.
  • Spacebar is your review loop: during a trim, the spacebar runs Play Around the edit point, looping the cut you just made.

Steps操作步骤

  1. In Trim Edit mode, select the edit point you want to trim (see Trim Edit Mode)
  2. Press W to enter Dynamic Trim Mode — the playhead turns yellowA yellow playhead means Dynamic Trim Mode is on
  3. Press L or J to push the edit point during playback; hold K and tap for frame-by-frame trimming
  4. Press the spacebar to play around the edit point and judge the cutThe spacebar loops playback around your trim
  5. Use ↑ / ↓ to jump to the next edit point; press W to exit when finished

Practice练习

  1. Select three consecutive edit points and trim each one while listening to the audio, then exit the mode.
  2. Trim the same edit point once with real-time L and once with K+L frame steps — feel the difference.

FAQ常见问题

JKL stopped playing the timeline?

You're probably still in Dynamic Trim Mode — check whether the playhead is yellow. Press W to exit and JKL becomes playback control again.

Dynamic trimming or plain dragging — which is better?

Depends on the cut. For rhythm- and feel-driven edits (music, action), trim live with playback; when you need exact frame counts, use Precision Trim Editor.

Can I trim several edit points in one session?

Yes — select multiple edit points before entering the mode, then jump between them with ↑ / ↓ and trim one at a time.
