自动对齐片段Auto Align Clips
学习目标LEARNING OBJECTIVES
学完你能在时间线上用 Auto Align Clips 按时间码或波形，把跨轨道的多个片段自动对齐。
概念说明CONCEPTS
自动对齐片段（Auto Align Clips）是时间线上的对齐命令：选中跨轨道的多个片段，Resolve 按时间码或波形把它们各自挪到同步位置——多机位剪辑的第一步。
- 工作在时间线上：与媒体池里的 自动同步音频 不同，它直接移动时间线片段的落点。
- 两种对齐依据：
Based on Timecode快而准；Based on Waveform靠各机位录到的同一段现场声互相匹配。 - 只挪位置不动内容：对齐只改变片段在时间线上的位置，不裁剪、不删素材。
- 多机位的前置动作：各机位分轨摆好后先自动对齐，再创建多机位片段进入多机位剪辑。
操作步骤STEPS
- 把各机位片段分别放到时间线的不同视频轨，位置大致接近即可
- 框选所有要对齐的片段
- 右键选
Auto Align Clips>Based on Waveform，有时间码就用Based on Timecode
- 放大时间线，抽查几处口型或动作，确认各轨已经对齐
练习PRACTICE
- 把同一场景的两个机位放到两条视频轨，用波形对齐并播放检查结果。
- 故意把其中一条挪偏约一秒，再跑一次自动对齐，观察它被拉回同步位。
常见问题FAQ
Auto Align Clips 和 Auto Sync Audio 是一回事吗？
不是。前者在时间线上挪动片段位置，做多机位对齐；后者在媒体池里把外录音频并进视频片段（见 自动同步音频）。
点了波形对齐却没反应？
检查每条片段是否都有可听见的现场声、片段间是否有内容重叠的时段。仍不行就换时间码方式，或放大波形手动对尖峰。
对齐完还差一两帧怎么办？
选中片段用 , / . 键逐帧微调，或放大时间线看清波形尖峰后手动补对。

After this card you can select clips across timeline tracks and use Auto Align Clips to sync them automatically by timecode or waveform.
Concepts概念说明
Auto Align Clips is a timeline command: select clips across multiple tracks, and Resolve shifts each one into sync based on timecode or waveform — the first step of multicam work.
- Works on the timeline: unlike Auto Sync Audio in the Media Pool, it moves where clips sit on the timeline.
- Two ways to align:
Based on Timecodeis fast and accurate;Based on Waveformmatches the same live sound recorded by each camera. - Positions only: aligning changes clip placement — nothing gets trimmed or deleted.
- The step before multicam: park each angle on its own track, auto-align, then build a multicam clip and start cutting angles.
Steps操作步骤
- Place each camera angle on its own video track, roughly in position
- Marquee-select every clip you want to align
- Right-click and choose
Auto Align Clips>Based on Waveform— orBased on Timecodeif you have it - Zoom in and spot-check lip sync or movement across the tracks
Practice练习
- Put two angles of the same scene on two video tracks, align them by waveform, and play back to check.
- Nudge one clip about a second out of place on purpose, run auto-align again, and watch it snap back into sync.
FAQ常见问题
Are Auto Align Clips and Auto Sync Audio the same thing?
No. The first moves clips on the timeline to sync camera angles; the second merges external audio into video clips in the Media Pool (see Auto Sync Audio).
I clicked waveform align and nothing happened?
Check that every clip has audible production sound and that the clips overlap in time. If it still fails, try timecode — or zoom into the waveforms and match the peaks by hand.
It's still a frame or two off after aligning — now what?
Select the clip and use , / . to nudge frame by frame, or zoom into the waveform spikes and fine-tune manually.
