Recomputing the Mouth Chart

When you generate the mouth chart for a sound in a sound element, you can either accept the mouth positions assigned by Harmony or assign your own lip-sync images.

However, if you change the sound's start frame or reassign its mouth position, you must reanalyze the sound and regenerate the mouth chart for it. This erases any manual modifications you may have made to the mouth assignments in the mouth chart.

To recompute the mouth chart for a selected sound from the Sound column:

1. In a Sound column in the Xsheet or Timeline view,right-click on a cell that contains the sound file you want to recompute the lip-sync for. Select Lip-Sync > Auto Lip-Sync Detection from the pop-up menu. The mouth position assignment for each frame is recomputed, erasing any modifications you have made.

To recompute the mouth chart for a selected sound from the Sound Element Editor:

1. Double-click the sound layer name in the Timeline view or the sound column header in the Xsheet view to open the Sound Element editor.
2. Click on the waveform in the Sound Element section in the Sound Element editor.
3. Right-click and select Auto-Lip Sync Detection.
