What Should I Do When "Apply to All Captions" Doesn't Work in Automatic Subtitling?

CapCut Online

Step1: Refresh the browser tab

• The web version relies heavily on JavaScript. A UI glitch may prevent the "Apply to all" command from propagating.
• Press Ctrl+R (Windows) or Cmd+R (Mac) to reload—your project is auto-saved to the cloud.

Step2: Check internet connectivity

• Style propagation in CapCut Web is partially handled server-side. A weak connection may interrupt batch updates.
• Wait 10–20 seconds after clicking "Apply to all" before assuming failure.

Step3: Avoid mixing auto and manual captions

• If you pasted text manually or imported SRT files, those captions won't respond to "Apply to all captions" for auto-subtitles.
• Only captions generated via "Auto Captions" > "Recognize Speech" are included in the global group.

Step4: Use Chrome or Edge at 100% zoom

• Browser scaling or unsupported browsers (e.g., Firefox) can cause rendering inconsistencies. Stick to recommended environments.

📍 Note: CapCut Web may show delayed updates for projects with >100 caption blocks. Be patient or split your video into shorter clips.

CapCut Desktop (Windows / macOS)

Step1: Verify caption integrity

• In the timeline, look for captions with different colors or borders—these indicate manual edits or errors.
• Right-click any inconsistent caption → choose "Reset to default style" before reapplying global settings.

Step2: Re-enable "Apply to all" after editing

• If you adjust timing or split a caption block after applying global style, the new segments may not inherit the style.
• Solution: Select one caption → open Text panel → re-check "Apply to all"

Step3: Clear render cache

• Go to Settings > Clear Cache. Corrupted preview cache can prevent style updates from displaying.

Step4: Export a test segment

• Render 10–15 seconds containing problematic captions.
• If the exported video shows correct styling, the issue is only in the preview, not the final output.

Step5: Update CapCut

• Older versions had bugs where "Apply to all" skipped captions beyond #50. Ensure you're on v6.0 or later.

📍 Tip: Desktop allows you to select multiple captions (Ctrl/ cmd + click) and apply style manually as a workaround.

CapCut Mobile App (iOS / Android)

Step1: Wait for background processing to complete

• After ticking "Apply to all captions," CapCut processes each subtitle block sequentially, especially in long videos (>5 minutes).
• Do not exit the text panel during this time—stay on the screen until all captions visually update.

Step2: Check if some captions were manually edited

• Any caption you've manually modified (e.g., changed text, split/merged segments) becomes "detached" from the global style group.
• These may not be affected by "Apply to all captions"

📍 Fix: Delete the manually edited caption and let CapCut regenerate it via "Auto captions" > "Regenerate."

Step3: Re-apply the style

• Tap any caption → open style panel → re-check "Apply to all" and confirm.
• Sometimes the toggle fails to register on first tap due to UI lag.

Step4: Restart the app

• Force-close CapCut and reopen the project. This refreshes the subtitle rendering engine and may sync pending updates.

📍 Note: On mobile, complex animations or custom fonts may cause partial rendering failures. Try using a simpler style first.

If the problem persists across all platforms with the same project, consider re-generating all subtitles from scratch:

1
1. Delete all existing captions
2
2. Go to Text > Auto Captions > Recognize Speech
3
3. Apply your desired style and tick "Apply to all captions" before making any manual changes
