Adding or Modifying Lip-sync Keys

The Voice track stores the audio file from the Import Audio panel or the Voice Script Library. The audio data is displayed in a wave form. You may double-click anywhere on the track to load an audio file.

Click the button on the Voice track to show the Lips track. You may manually add lip-synching keys to this track by double-clicking on the cells in this track.

The lip synchronization effect is applied to only a small section of the script and indicated on the Lips track by a grey box. To access the Lip Sync panel, click the Lip Sync button in the Timeline.

Sometimes the Auto Motion may affect the accuracy of the lips shape. You may follow the steps below to force the lip movements to sync with the sound.

1. Given the settings in Auto Motion change the original lips shape when pronouncing the sound "B".

   The lips shape is affected by the Auto Motion. When the jaw moves down, the lips shape is not correct for a "B" sound.

2. Double-click on the lip key "B.M.P" to access the Lip Sync panel.
   
3. Drag the Expressiveness slider to enhance the result if necessary.
4. Activate the Lip-sync constraint over the Auto Motion option.
   
5. Click the Apply button to blend the lip keys you have modified with the entire Auto Motion for a more accurate animation result.

   After modification, the lips shape is constrained for the "B" sound.

   Note:

   Once you click the Apply button, all of the lip keys in the Auto Motion clip will be affected. You may alternatively click the Apply button in the Auto Motion Settings panel for the same result. Some visemes, such as "EE", "Ih", "Ah", "Oh", and "W_OO", will not be affected by voice strength or any adjustment in the Auto Motion.
