Why Audio & Video Sync Matters in Video Editing

Even a half-second delay can make your video feel unprofessional.

That’s why learning to automatically sync audio and video in CapCut is an essential skill for modern creators.

What You Need Before Syncing Audio in CapCut

Before using CapCut’s one-click sync feature, make sure you have:

CapCut uses waveform matching to align both files accurately.

Now let’s get into the main process.

Step 1: Import Video and Audio into CapCut

  • Open CapCut

  • Create a new project

  • Import:

    • Your video clip

    • Your external audio file

Drag both onto the timeline.

Step 2: Select Both Audio and Video Clips

  • Hold Shift (desktop) or long-press (mobile)

  • Select:

    • The video clip

    • The external audio clip

This step is important—CapCut only syncs when both clips are selected.

Step 3: Click “Sync Audio” (ONE Click)

  • Right-click (desktop) or tap Edit

  • Select “Sync Audio with Video”

That’s it.

CapCut will automatically align the audio perfectly with the video—no manual dragging, no guessing, no zooming into waveforms.

Step 4: Remove Camera Audio (Optional but Recommended)

Once synced:

  • Mute or delete the original camera audio

  • Keep only the clean external audio

This instantly improves sound quality.
