学习目标LEARNING OBJECTIVES

学完你能说清三点编辑（Three-Point Editing）"四点取三"的原理，并用 Insert 和 Overwrite 把素材精确放上时间线。

概念说明CONCEPTS

三点编辑（Three-Point Editing）是 Resolve 计算"素材放哪里、放多长"的基本规则——源片段的入/出点加时间线的入/出点共四个点，你定任意三个，系统自动算出第四个。

  • 四点取三：源 In、源 Out、时间线 In、时间线 Out 中定三个，落点和时长就唯一确定。
  • 少打也能剪：播放头本身就是隐含的一个点，素材的头尾也是——不手动标点，系统照样用隐含点。
  • Insert 不覆盖：插入编辑把新片段塞进来，后面的内容整体右移，谁都不丢。
  • Overwrite 会盖：覆盖编辑用新片段盖掉等长的旧内容，时间线总长不变。
  • 入口在查看器：把源片段拖到时间线查看器画面上，会浮现 Insert、Overwrite 等叠加层，拖到哪个执行哪个。

操作步骤STEPS

  1. 给源片段打好入点和出点（见 入点和出点）
  2. 把时间线播放头移到新片段要开始的位置
  3. 按住源查看器画面中央，把片段拖到时间线查看器上，先别松手
  4. 拖到浮现的 Insert 叠加层上松手，片段插入且不覆盖任何内容时间线查看器上的编辑叠加层
  5. 回放检查：新片段出现，原有内容整体后移

练习PRACTICE

  1. 在两段素材之间用 Insert 插入一个新镜头，确认时间线总长变长了。
  2. 用 Overwrite 把刚插入的镜头换成另一段素材，确认总长不变。

常见问题FAQ

我只打了一个入点，能编辑吗？

能。系统会用播放头和素材的头尾补足其余的点——"三点"里本来就允许隐含点。

Insert 和 Overwrite 到底怎么选？

问自己一句：后面的内容要不要动？要往后推就选 Insert，原地换掉就选 Overwrite。

想让新片段精确落在某一段区域怎么办？

在时间线上也打入点和出点圈出区域，再执行编辑——给 B-roll 精确定位就是这个打法（见 叠加编辑）。

Learning Objectives学习目标

After this card you can explain the "three of four points" logic of Three-Point Editing and place clips precisely with Insert and Overwrite edits.

Concepts概念说明

Three-Point Editing is Resolve's basic rule for calculating where a clip goes and how long it runs — the source In/Out plus the timeline In/Out make four points; set any three and Resolve works out the fourth.

  • Three of four: fix any three of source In, source Out, timeline In, and timeline Out, and the landing spot plus duration are locked in.
  • Fewer marks still work: the playhead counts as an implied point, and so do the clip's head and tail — with no manual marks, implied ones are used.
  • Insert never overwrites: an Insert edit squeezes the new clip in and shifts everything after it to the right — nothing is lost.
  • Overwrite does: an Overwrite edit covers the same length of existing content, leaving the total duration unchanged.
  • The viewer is the entry point: drag the source clip onto the timeline viewer and overlays like Insert and Overwrite appear — drop on one to perform it.

Steps操作步骤

  1. Mark In and Out points on the source clip (see In & Out Points)
  2. Move the timeline playhead to where the new clip should start
  3. Drag from the center of the source viewer onto the timeline viewer — don't release yet
  4. Drop onto the Insert overlay that appears — the clip goes in without covering anythingEdit overlays on the timeline viewer
  5. Play it back: the new clip is there and everything after it has shifted

Practice练习

  1. Use Insert to add a new shot between two clips and confirm the timeline got longer.
  2. Use Overwrite to swap that shot for a different one, and confirm the total duration stayed the same.

FAQ常见问题

I only set one In point — can I still edit?

Yes. Resolve fills in the rest from the playhead and the clip's head or tail — implied points have always counted.

How do I choose between Insert and Overwrite?

Ask one question: should the later content move? If yes, Insert; to replace it in place, Overwrite.

How do I make a clip land exactly on a specific region?

Mark In and Out points on the timeline to fence off the region before you edit — that's how B-roll gets placed precisely (see Append Edit).
