Through this class I learned lip syncing in animation:
Lip syncing and facial animation: two goals
- Jaw bounce: the underlying structure:A lip sync should be built upon a solid jaw bounce rhythm
- Emotional speech: underlying emotional structure:Facial animation should capture emotions not just move. All movement has purpose and matches the dialogue
Lip syncing in 3D: basic process:
- Jaw bounce (rhythm)
- Open& close
- wide & short(visemes)
- Curl in & out (visemes)
- Tongue (flicking/internal sounds)
- Details (visemes-readability,emotions, mouth shapes)
- Associated /part of facial animation
- Check puffing/ shrinking(pressure)
- Nose (movement driven by the jaw/mouth)
- Jaw tilt (angle of the mouth driven by speech/ emotions)
Creating a ‘Jaw Bounce’ animation：Adjust the opening and closing of the chin
Creating a ‘Viseme’ animation：Adjust the size of your mouth (lengthen or rounder) ,turning your lips inside or outside and your tongue up and down
Mouth enhancements: Adjust lips up and down, turn lips inside and out, inflate and deflate the mouth and move nose up and down. The last step is to adjust the teeth.
Upper hemisphere (Brows & eyes):Adjust the movement of eyebrows and brow center, adjust the displacement of eye gaze, adjust the movement of upper and lower eyelids. Add blinking of eyes and move frames appropriately.
