学习目标LEARNING OBJECTIVES

学完你能用替换编辑（Replace Edit）把时间线上的镜头快速换成备用素材，并用两个播放头精确对齐关键帧。

概念说明CONCEPTS

替换编辑（Replace Edit）用源查看器（Source Viewer）里的新片段整段换掉时间线上的旧片段——不靠出入点，靠时间线播放头和源播放头的位置对齐。

  • 换镜头不动结构：新片段落在旧片段的位置上，时间线结构和相邻片段都不受影响。
  • 播放头即对齐点：源片段播放头所在的帧，会对齐到时间线播放头所在的帧——两个播放头决定一切。
  • 标记辅助定位：源片段里按 M 打标记（Marker），再用 Shift-Up/Down Arrow 在标记间跳转，快速找到那句词。
  • 换机位神器：源与时间线时间码一致时，替换编辑能精准换成同一时刻另一机位的画面。
  • 换完顺手收尾：新镜头节奏不同，就用波纹修剪（Ripple Trim）把长度收顺（见 修剪编辑模式）。

操作步骤STEPS

  1. 把时间线播放头停在旧片段需要对齐的帧上（如那句台词的开头）
  2. 双击媒体池中的新片段，在源查看器中打开
  3. 把源播放头定位到对应帧——有标记时按 Shift-Up/Down Arrow 直接跳转源播放头对齐到标记帧
  4. 从源查看器拖到时间线查看器的 Replace 叠放区，旧片段即被替换拖到时间线查看器的 Replace 叠放区
  5. 播放检查；新片段偏长时按 T 用波纹修剪收尾

练习PRACTICE

  1. 把一个采访镜头替换成另一条 take，用两个播放头对齐同一句台词的开头。
  2. 在源片段上打两个标记，练熟 Shift-Up/Down Arrow 跳转后再执行一次替换。

常见问题FAQ

替换后新片段长度和旧的不一样？

正常。替换编辑以播放头对齐为准，不迁就旧片段的长度；换完用波纹修剪把衔接收顺即可。

为什么拖过去没有 Replace 选项？

要拖到时间线查看器（右屏）的叠放区，不是时间线轨道。拖到轨道上是覆盖或插入，不是替换。

替换和覆盖编辑怎么选？

要"帧对帧"精确对齐（换 take、换机位的同一时刻）用替换；按区间铺素材用覆盖（见 三点编辑）。

After this card you can use the Replace Edit to swap a timeline clip for alternative footage, aligning the exact frame with two playheads.

Concepts概念说明

A Replace Edit swaps an entire timeline clip for whatever sits in the Source Viewer — no In and Out points; alignment comes from where the timeline playhead and the source playhead are parked.

  • New shot, same structure: the new clip lands exactly where the old one sat; the timeline and its neighbors are untouched.
  • Playheads are the alignment: the frame under the source playhead lines up with the frame under the timeline playhead — two playheads decide everything.
  • Markers speed you up: press M to drop a Marker in the source, then jump between markers with Shift-Up/Down Arrow to find that exact line.
  • Multicam magic: when source and timeline share timecode, Replace swaps to the same moment from another camera angle.
  • Tidy up after: if the new take runs at a different pace, finish with a Ripple Trim (see Trim Edit Mode).

Steps操作步骤

  1. Park the timeline playhead on the frame the new clip must align to (e.g. the start of that line)
  2. Double-click the new clip in the Media Pool to open it in the Source Viewer
  3. Move the source playhead to the matching frame — with markers, press Shift-Up/Down Arrow to jump straight thereSource playhead aligned to the marker frame
  4. Drag from the Source Viewer onto the Replace overlay in the timeline viewer — the old clip is swappedDragging onto the Replace overlay in the timeline viewer
  5. Play it back; if the new clip runs long, press T and ripple trim the tail

Practice练习

  1. Replace an interview shot with another take, aligning both playheads to the start of the same line.
  2. Drop two markers on a source clip, practice jumping with Shift-Up/Down Arrow, then run another replace.

FAQ常见问题

The new clip is a different length than the old one?

That's normal. Replace aligns by playheads, not by the old clip's length; ripple trim the join afterwards and you're done.

Why don't I see a Replace option when I drag?

Drag onto the overlay in the timeline viewer (the right-hand screen), not onto the timeline track. Dropping on the track is an overwrite or insert, not a replace.

Replace or Overwrite — which do I pick?

Use Replace for frame-accurate swaps (same line in another take, same moment on another camera); use Overwrite when you're covering a marked range (see Three-Point Editing).
