FaceFX is real-time, and very good. For example, Bioware used FaceFX in their games. But - it’s expensive. $900 for FaceFX Studio + royalty from renevue above $500,000.
That’s how my dialogue plugin looks with Text To lip-sync plugin: https://youtu.be/U6yz2XchM64 . As I said, it’s far from perfect.
May be you’re right, and I should combine these two plugins in a bundle.
