Lip Syncing in Blender Grease Pencil with the Time Offset Modifier

In part 1 of this video series, I'll show you how to set up the Time Offset Modifier in Blender Grease Pencil so you can lip sync your animations through mouth substitutions (also called mouth swaps). This process can also be applied to various body parts, such as eyes, eyebrows, hands, and feet. Toon Boom Harmony offers a great workflow for this type of process, so I wanted to try to accomplish something similar in Blender Grease Pencil. 

In the second video, I'll show you how to create drivers so you can animate the mouth by selecting drawings from a mouth chart onscreen.
