🗣️ Lip Sync

Make any character in a video appear to speak by syncing mouth movements to audio. Upload a video and audio file 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 Image or Video panel
• Upload your audio file (2s-120s) in the Upload Audio panel
• Select your AI model
• Click Generate
• 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

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