Could I get these results of this up/down stage by Bake Sound the F-Curves and driving the z-axis of the jaw bone? If not, what is missing from that method?
The mouth is not only moved by one Bone. You have no control. I also think that the volume is not directly correlated to how far the mouth is opened, let alone to the mouth shape.
Might work on a background character or on a robot, You can of course give it a try to see how it looks.
But it would also defeat the purpose of this course to learn lip sync, I think.
Wayne will come up with a better answer, I'm sure.
That's an interesting thought Benjamin_Bass
It would get you a cheap and dirty starting point for the jaw, but as Spikey mentioned, it's not exactly how the jaw (and mouth) actually moves.
You would still need to clean that up - so it might not save you much time.
