学习目标LEARNING OBJECTIVES

学完你能从源查看器的当前帧出发，让时间线播放头自动跳到使用该帧的片段上，在源素材和时间线之间双向穿梭。

概念说明CONCEPTS

反向匹配帧（Reverse Match Frame）是从源查看器找回时间线的定位操作——源播放头停在哪一帧，时间线播放头就跳到使用该帧的片段上，与匹配帧（Match Frame）方向相反。

  • 方向与匹配帧相反：匹配帧从时间线找源素材（见 匹配帧），反向匹配帧从源素材找时间线。
  • 按帧精确对应：两个播放头停在同一画面上，逐帧对齐，不差一格。
  • 从当前位置向后找：时间线播放头跳到它当前位置之后的第一处匹配；想找最前一处，先把它移回时间线开头。
  • 找不到就不动：该帧没剪进时间线时命令无效，播放头原地不动。

操作步骤STEPS

  1. 在源查看器中打开已剪进时间线的片段，把源播放头停在要查找的那一帧
  2. 把时间线播放头移到想开始搜索的位置（找第一处就移回开头）
  3. 点源查看器右下角的 Match Frame 按钮，或直接按 F源查看器右下角的 Match Frame 按钮
  4. 时间线播放头自动跳到匹配片段的同一帧上
  5. 停在源查看器再按一次 F，继续找该帧在时间线里的下一处使用

练习PRACTICE

  1. 挑一个时间线片段按 F 找到源帧，再在源查看器按 F 跳回时间线，往返三次。
  2. 把同一段素材剪进时间线两处，用反向匹配帧从源查看器依次找出两个使用位置。

常见问题FAQ

按了 F 时间线没反应？

多半是这一帧根本没剪进时间线——反向匹配帧只认已使用的素材范围。换一个确定用过的片段再试。

同一段素材用了好几次，它跳到哪一处？

跳到时间线播放头当前位置之后的第一处匹配。想从头找起，先把时间线播放头移回开头再按 F。

反向匹配帧会改动我的时间线吗？

不会。它只移动播放头，不增删片段、不动出入点，是纯定位操作。

After this card you can start from a frame in the Source Viewer and jump the timeline playhead straight to the clip that uses it — shuttling freely between source and timeline.

Concepts概念说明

Reverse Match Frame locates the timeline from the Source Viewer — whatever frame the source playhead sits on, the timeline playhead jumps to the clip using it. It's Match Frame running in the opposite direction.

  • Opposite of Match Frame: Match Frame goes from the timeline to the source (see Match Frame); Reverse Match Frame goes from the source back to the timeline.
  • Frame-accurate: both playheads land on the same image — not one frame off.
  • Searches forward: the timeline playhead jumps to the first match after its current position; to find the earliest use, park it at the start of the timeline first.
  • No match, no move: if the frame was never edited into the timeline, the command does nothing.

Steps操作步骤

  1. Open a clip that's already in the timeline in the Source Viewer, and park the source playhead on the frame you want to find
  2. Move the timeline playhead to where the search should start (go to the very beginning to find the first use)
  3. Click the Match Frame button at the bottom right of the Source Viewer, or simply press FThe Match Frame button at the bottom right of the Source Viewer
  4. The timeline playhead jumps to the same frame on the matching clip
  5. Stay in the Source Viewer and press F again to find the next use of that frame

Practice练习

  1. Pick any timeline clip, press F to find its source frame, then press F in the Source Viewer to jump back — do the round trip three times.
  2. Edit the same source range into the timeline twice, then use Reverse Match Frame to locate both uses one after the other.

FAQ常见问题

I pressed F and nothing happened?

Most likely that frame was never edited into the timeline — Reverse Match Frame only works on media that's actually used. Try a clip you know is in the cut.

I used this shot several times — which one does it jump to?

It jumps to the first match after the timeline playhead's current position. To search from the top, move the timeline playhead back to the start, then press F.

Does Reverse Match Frame change my timeline?

No. It only moves the playhead — no clips added or removed, no marks touched. Pure navigation.
