Is there a way to exaggerate motions?

Deke

I'm trying to improve lip-sync.  Currently I use the lip-sync function in Daz 32-bit on a Mac. Then I save as a pose preset and import the motion to a project in 64-bit so I can render with Iray.

The problem is the lip-movements are imprecise. There is no way to scrub through a scene with audio to refine them. I'm experimenting with slowing the spoken line of dialogue down, thus rendering more frames, and then speeding up later in the process.  But the mouth movements are stil quite sublte. Animation in general tends toward more exaggerated moves.

Is there a way to exaggerate a lip-syn animation?  Maybe using Graphmate?
