# AI Lip-sync

# 🗣️ How do I lip-sync a character to the voiceover?

The Lip Sync tab matches a character's mouth and facial movements to the scene's voiceover (or custom audio). It adds real talking-head realism and works best on clear, forward-facing faces. There are two sub-tabs: **AI Lip Sync** (automatic) and **Actor Mode** (more control).

* Scene image auto-loaded in preview
* **Prompt**: To convert from an Image directly into an animated lip-sync motion, mention the scene context to guide the lip sync in the prompt box.

* **Actor Mode**: Use the actor mode if you want an output very specific. You need to upload/record a driving video. Facial movements and expressions of the uploaded / recorded video will be transferred to the AI video.

###### Tips
Here are some tips to get the best results:
* Works best on close-up or medium shots with a clearly visible, forward-facing face
