先学：Prerequisites: 修剪

学习目标LEARNING OBJECTIVES

学完你能用波纹修剪（Ripple Trim）单边调整编辑点，让后续片段自动跟随，删掉空隙或压缩节奏。

概念说明CONCEPTS

波纹修剪（Ripple Trim）是只动编辑点一侧、把时长变化"传导"给后面所有片段的修剪——片段缩短，后面整体提前；片段拉长，后面整体推后。

  • 总长会变：与滚动编辑相反，波纹改变时间线总时长——这正是它调节奏的价值。
  • 只带后面的：只有从该编辑点之后开始的片段被带动；更早开始的上层 B-roll 原地留守，可能与下层错位。
  • 间隙也能修：波纹可以选中空隙（gap）一侧的边缘，直接拉长或缩短间隙本身。
  • 修剪模式专属：波纹只在 Trim Edit 模式（T）下可用；Selection 模式拖边缘不会带动任何后续片段。
  • 可多点齐修：Cmd/Ctrl 单击加选多个编辑点（跨轨也行），一次拖动同步调整。

操作步骤STEPS

  1. 按 T 进入 Trim Edit 模式
  2. 把指针靠近编辑点、偏向要修剪的那一侧，出现指向该侧的波纹（Ripple）图标编辑点单侧的波纹修剪图标
  3. 单击选中该侧（只有单边高亮），左右拖动：左拖缩短、右拖拉长
  4. 观察后续片段整体跟随移动，对照查看器双画面对帧波纹修剪带动后续片段一起移动
  5. 松手后回放，重点检查上层素材与下层主画面是否仍然对齐

练习PRACTICE

  1. 把某片段尾部向左波纹缩短约 1 秒，确认后续片段整体提前、总长变短。
  2. 选中间隙右端靠间隙一侧的编辑点向左拖，合上空隙后检查上层 B-roll 是否仍对位。

常见问题FAQ

波纹和滚动到底怎么区分？

波纹动一侧、带后面、总长变；滚动 滚动编辑 两侧联动、总长不变。删空隙压节奏用波纹，纯挪切点用滚动。

为什么波纹之后上层素材错位了？

只有编辑点之后开始的片段会被带动，更早开始的上层 B-roll 留在原地。撤销后用 Cmd/Ctrl 加选多个编辑点一起修。

波纹能同时修音频吗？

能。Linked Selection 开启时，声画两侧的编辑点一起被选中、一起被带动；只想动视频就先关掉它。

After this card you can use Ripple Trim to adjust one side of an edit while every later clip follows, closing gaps and tightening pacing.

Concepts概念说明

Ripple Trim moves only one side of an edit point and lets the duration change "ripple" through every later clip — shorten a clip and everything after it pulls earlier; lengthen it and everything pushes later.

  • Total duration changes: the opposite of a roll edit — and exactly why ripple is the pacing tool.
  • Only later clips follow: only clips starting at or after the edit move; upper-track B-roll that began earlier stays put and can slip out of sync with what's below.
  • Gaps are trimmable too: ripple can grab the edge of a gap itself and stretch or shrink it directly.
  • Trim Edit mode only: ripple lives in Trim Edit mode (T); dragging an edge in Selection mode never pulls later clips along.
  • Trim many points together: Cmd/Ctrl-click to add edit points — across tracks too — and adjust them all in one drag.

Steps操作步骤

  1. Press T to enter Trim Edit mode
  2. Hover near the edit point, on the side you want to trim, until the ripple icon pointing that way appearsThe ripple trim icon on one side of an edit
  3. Click to select just that side (only one edge highlights), then drag — left to shorten, right to lengthen
  4. Watch every later clip travel with your drag, using the viewer's two-up display to match framesA ripple trim carrying all later clips along
  5. Release and play back, checking that upper-layer cutaways still line up with the main picture

Practice练习

  1. Ripple the tail of a clip about a second shorter to the left, and confirm the later clips pull in and the timeline gets shorter.
  2. Select the gap-side edge at the right end of a gap and drag left to close it, then check the B-roll above is still in sync.

FAQ常见问题

How do I tell ripple and roll apart?

Ripple moves one side, carries later clips, and changes total duration; roll Roll Edit links both sides and keeps duration. Ripple to close gaps and fix pacing; roll to move a cut.

Why did my upper-layer clips slip out of sync after rippling?

Only clips starting after the edit get carried along — earlier-starting B-roll stays put. Undo, then Cmd/Ctrl-click to select the extra edit points and trim them together.

Can ripple trim audio at the same time?

Yes. With Linked Selection on, the audio and video sides of the edit are selected and rippled together; turn it off to move picture only.
