How to Fix Multiple Captions Showing at Once in the Exported Video?

CapCut Online

Diagnosis & Fix:

1
1. Open your project at CapCut.
2
2. Examine the timeline:

     Scroll vertically to see if there are two or more text tracks. Auto-captions and manual text appear as separate horizontal lanes.

3
1. Delete redundant tracks:

     Click the extra text clip → press Delete on your keyboard, or click the ⋯ (more) menu → Delete.

4
1. Resolve time overlaps in a single track:

     Even in one caption lane, adjacent subtitles may bleed into each other due to long durations.

     Zoom in using the + button or Ctrl/Cmd + scroll, then shorten clip durations so they end before the next begins.

5
1. Re-generate captions if needed:

     If corruption is suspected, delete all captions and re-add via Text → Auto Captions.

6
1. Export again and check the output.

📍 Note: Browser caching can sometimes cause preview glitches—always test the final downloaded file, not just the in-browser preview.

CapCut Desktop (Windows / macOS)

Diagnosis & Fix:

1
1. Open the project in CapCut Desktop.
2
2. Inspect the timeline:

     Look for multiple text tracks under the video/audio tracks. Auto-captions usually appear as one continuous block; manual text appears as separate clips.

3
1. Remove duplicate layers:

     Click the unwanted text track → press Delete on your keyboard, or right-click → Delete.

4
1. Check intra-track overlaps:

     Within a single caption track, ensure no two subtitle clips share the same time range.

     Zoom in (Ctrl/Cmd + scroll) and adjust clip boundaries by dragging their edges.

5
1. Use the Caption Editor to clean up:

     Right-click the caption block → Edit Captions → review for unintended line duplications.

6
1. Re-export the project and preview the result.

📍 Tip: Use "Lock" on your main caption track to prevent accidental additions during editing.

CapCut Mobile App (iOS / Android)

Diagnosis & Fix:

1
1. Open your project in CapCut.
2
2. Go to the timeline and look for multiple text tracks (you may see 2+ subtitle layers stacked vertically).
3
3. Identify duplicates:

     One layer may be auto-generated captions (labeled "Captions"),

     Another may be manually added text that looks identical.

4
1. Delete the unwanted layer:

     Tap the extra text clip in the timeline → tap Delete (trash icon).

5
1. Check for overlapping segments:

     Even within a single caption track, two subtitle blocks might overlap in time.

     Zoom in on the timeline (pinch to zoom), then drag or trim clips so they don't play simultaneously.

6
1. Re-export the video to verify the fix.

📍 Tip: Avoid adding manual text while auto-captions are active—use Edit Captions instead to modify existing ones.

Summary:

Multiple captions appearing together almost always originate from layer duplication or timing overlap in the editing timeline—not external files. The solution is to clean up your project's text tracks before exporting, regardless of platform. Always preview your video in the editor with sound to catch sync or stacking issues early.
