Having trouble completing Lip Sync in CapCut? Whether you’re using a still image or a full video with a pre-recorded monologue, it’s frustrating when Lip Sync fails midway — usually between 20% to 90%. If the “Vivid Talking Face” option worked yesterday but suddenly stopped today, you’re not alone.
In this post, we’ll cover how to fix CapCut Lip Sync on PC, iOS, and Android, and suggest powerful alternatives like D-ID, HeyGen, and Runway ML that can help you create realistic talking videos with ease.
Fix CapCut Lip Sync Not Working
For CapCut on PC (Desktop)
If Lip Sync keeps crashing or failing:
- Switch from a still image to a short video (even 1–2 seconds works better)
- Use a clean monologue — avoid background music or overlapping edits
- Go to Settings > Clear Cache
- Make sure your internet connection is stable — Lip Sync is cloud-based
- Reboot your PC and try again with a fresh project
- Check for updates via Profile > Check for Updates
For CapCut on iPhone or Android
Lip Sync issues on mobile may be due to:
- Very long audio clips
- Low-resolution or heavily filtered images
- Server-side processing failures
Fixes:
- Use a clean, high-quality image
- Keep audio short and simple (<15 seconds)
- Try recording the voice inside CapCut instead of importing
- Reinstall CapCut if necessary (your Pro plan and projects will restore if you’re logged in)
- Wait a few hours — CapCut AI servers may be under load
