If your template export in CapCut appears frozen, stops at a certain percentage, or fails without completing, this is often due to system resources, connectivity, or project complexity—not a permanent error. CapCut's export capabilities vary by platform:
CapCut Web (CapCut Online)
Why Does It Happen:
Exports rely entirely on your browser and internet connection. Large projects may exceed browser memory limits or time out during cloud rendering.
What To Do:
- Wait Patiently: Cloud rendering can take several minutes for HD/4K videos—do not close the tab.
- Use Chrome or Edge: These browsers handle media encoding most reliably.
- Check Your Internet: A stable connection (≥10 Mbps) is required throughout the entire export.
- Simplify Your Project: Reduce clip count, remove heavy effects (e.g., "Glitch" or "3D Zoom"), or lower resolution before re-exporting.
- Clear Browser Cache: Go to browser settings → Privacy → Clear browsing data (cached images/files).
📍 Tip: If export fails repeatedly, click "Save to Cloud" first. Then reopen the project from My Projects and try exporting again with fewer layers.
CapCut Desktop (Windows/macOS)
Why Does It Happen:
Export runs locally, so failures usually stem from insufficient RAM, GPU driver issues, disk space, or background processes interrupting rendering.
What To Do:
- Free up System Resources: Close other apps (especially browsers or design software).
- Ensure Enough Storage: You need at least 2–3 GB free space on your export drive.
- Update Graphics Drivers: Outdated GPU drivers commonly cause rendering freezes.
- Export to A Local Folder: Avoid saving directly to cloud-synced folders (e.g., OneDrive, iCloud).
- Restart CapCut or Your Computer: This clears stuck background processes and temporary files.
⚠️ Important: CapCut Desktop does not have an in-app "Clear Cache" button. To manually reset temp files:
- Windows: Delete contents of %LocalAppData%\CapCut\
- macOS: Remove items in ～/Library/Caches/com.lemon.lvoverseas/
Then restart the app.
📍 Tip: Desktop offers the fastest and most reliable exports. For long or high-resolution templates, always use this version.
CapCut Mobile App (iOS/Android)
Current Limitation:
As of January 2026, the mobile app supports template editing and export, but is highly sensitive to device performance and interruptions.
Why Export Fails on Mobile:
- Screen lock or switching apps pauses rendering
- Low storage or battery optimization kills the process
- Overheating triggers thermal throttling (common on older devices)
What To Do:
- Keep the app in the foreground and disable auto-lock during export.
- Free up storage: Ensure >1 GB available on your device.
- Lower export quality: Tap "Resolution" before exporting and choose 1080p instead of 4K.
- Disable battery saver mode, which may restrict CapCut's background activity.
- Restart your phone if exports consistently stall at the same point.
📍 Tip: If your mobile export fails repeatedly, send the project to CapCut Desktop via "Sync to Cloud" and export from there.
🔑 Key Actions to Prevent Export Failures
Always save your project before exporting—use Save to Cloud (Web/Desktop) or Save to Gallery (Mobile).
- 1
- Avoid Overly Complex Templates: Too many overlays, transitions, or audio tracks can overwhelm the renderer. 2
- Update CapCut Regularly: Bug fixes for export stability are included in monthly updates. 3
- Monitor Progress: On Desktop/Web, watch the progress bar—stuck at 99% often means final file writing is blocked by antivirus or disk permissions. 4
- Be Patient with Large Files: A 5-minute 4K video can take 10+ minutes to export, depending on your hardware.
While occasional export delays are normal—especially on mobile—following these steps will help you complete your video successfully. For professional or time-sensitive work, CapCut Desktop remains the most stable and efficient choice.
