Hello. Im trying to create 4 key frames or mouth positions in after effects. The rest or regular mouth, the o position, half open, then fully open. Though I've come across some trouble. i want them to be placed in the video matching where the shapes go with the sound but it's seems like if i create 4 key frames they just will always be changing to the next thing and not staying in the shape i want them too. Does anyone know a better way or a solution. I apologize if this did not make any sense. Thank you!
