How do I add visemes?
I've been editing my almost perfect automatic lip sync. The most common problem is any "P" between a vowl and an "S" like "Keeps". Easy fix. Delete one frame between the "E" and the "S" and the neutral closed mouth looks exactly like a "P". Perfect
However, in another instance, the computer mistook my "F" for an "S". It's an easy mistake that I expect a non-English speaking human would make, but how do I add an F? Do I need to look for another F and copy/paste it? Should I record and F over the top? What's the intended workflow here?
