Here are two timelapses we set up for some dialogue scenes from An Gadhar Dubh.
In the second video you can see the jaw substitutions on the bottom of frame, alongside the dialogue X-sheet.
We used a similar method for all characters with dialogue, many of which needed multiple angles; so for Peadar, the main character, we have 25 mouth shapes (9 key mouth shapes with softer variations for nuanced performance) and 25 heads in a full rotation. Thankfully the heads viewed from the back don’t require jaw substitutions (we’re not that mad), but we ended up with about 440 different jaws for just that one character.
