Batman Lip Sync in Blender Grease Pencil Part 2: Keyframing Mouths Visually in the Viewport

In part 2 of this video series, I’ll show you how to use the Time Offset Modifier in Blender Grease Pencil with a driver so you can lip sync your animations through mouth substitutions (also called mouth swaps) visually within the viewport using a mouth chart. 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.
