Adding a lip-sync to a project can really enhance its quality and storytelling. However, it can be difficult to shape a character's mouth to match the sound at a precise frame.
To solve this problem, Harmony provides a lip-sync feature which analyzes the contents of a sound element and generates a mouth chart (see below) based on the eight animation phonemes (A, B, C, D, E, F, G, and X for silence).
The mouth shapes used by Harmony are based on the conventional mouth chart used in the animation industry.
Here is an approximation of the sound each mouth shape can produce:
|•||A: m, b, p, h|
|•||B: s, d, j, i, k, t|
|•||C: e, a|
|•||D: A, E|
|•||F: u, oo|
|•||G: f, ph|
|•||X: Silence, undetermined sound|
You can lip-sync the traditional way or let the system automatically create the basic detection.
You can refer to the mouth chart positions as you draw the shape of the character's mouth.
