🗣️ How do I lip-sync a video?

Lip Sync makes a character in a video appear to speak by matching their mouth movements to an audio file. Upload a video (or image) and an audio track to get started.

Lip Sync Steps

Follow these steps to get started:

• Go to Video → Lip Sync.
• Upload your image or video (max 200 MB) in the Upload panel.
• Upload your audio file (2s–120s) in the Upload Audio panel.
• Select your AI model.
• Click Generate, then preview and download.

Tips
Here are some tips to get the best results:

• Use a clear, forward-facing image or video for best lip sync accuracy
• Keep audio clean - background noise reduces sync quality

Common Issues
If you run into problems, here are the most common issues and how to resolve them:

• Lip sync looks unnatural - ensure face is clearly visible and forward-facing
• Audio not syncing - check audio length is between 2 to 120 seconds
