Rendered lip movements muted compared to in-engine

Hello! I’ve been playing with audio2face. It looks great in the engine. However, when I render it out to a movie the lip animations (actually all facial animations) become extremely muted.

Am I missing a setting?

Left hand side is in the editor, right hand side is a render.

I guess I’m not allowed to upload videos here, but the video is embedded here:

I really can’t figure out what to do here.
