Applying Lips Synchronization

You may change or correct the mouth shape of the talking actor. Applying lip synchronization makes the lip movements match the words being spoken by the actor. To access the Lips Sync panel, click the Lips Sync button in the Timeline.

1. Click the Scale button (Shortcut: S) on the left-side tool bar to zoom in the mouth area. Press the space bar repeatedly to playback, and pause, where the actor's lips not sync to the voice.
2. Click the Timeline button (Shortcut: Windows - F3; Mac - fn + F3) to access the Timeline panel.
3. Click the arrow button of the Voice track to display the Lips track. You may find the lip movements in this voice script, displayed in grey boxes.
   
4. Double-click on the problem grey box ("Ah" for the example) to access the Lips Sync panel.
5. Move the Expressiveness slider to the right, to put emphasis on the lip movement. The mouth shape of the actor will then changes accordingly. You may also replace the mouth shape by clicking another viseme or phonetic sound displayed in the panel.
   

   Expressiveness = 50	Expressiveness = 100

6. Click the Home button (Shortcut: Home) on the left-side tool bar to restore original position of the actor.
