how to lip sync

ive had trouble with this ever since i tried it out
i never got it right
i know i'd use keyframing now but how exactly do i do it?

It gets pretty tricky because it's so subtle. If anything, one piece of advice you can use to successfully lipsync anything is to just watch someone say it.

Just don't lip sync like family guy or simpsons where they move their ips to every sound. It doens't work like that, people don't move their lips like that in real life.

For example , that guy Antoine Dodson in the bed intruder video at one point says, "You are so dumb."
I noticed when he says "you are," it really almost looks like he's saying "you're," even though he most definitely said the first thing.
So basically whenever we talk with our lips and mouth, we are always cutting corners with it without even thinking about it.

Richard Williams talks all about it in that book, "The Animator's Survival Kit."

Do have a look at the mouth positions though:

Omg, idk hwo anyone can have a problem with that every time i have tried it it looks perfect unless im subing jap audio :p but i double frame alot with lip syncying what i do is the places were you hear A O L S W place in the mouths then fill it in with whatever seems about right
