Smooth lip syncing for phonemes
Hi,
I’ve got a bit of an issue with my character’s phonemes.
I’ve got all the phonemes for my character in a precomp, it’s time remapping is being controlled by a null object’s slider control, so that’s all good.
But since I lock the keyframes the phonemes abruptly appear at every change so it looks like he’s talking too fast.
Is there any way for me to smooth out this transition or will I have to use a different method to set up my phonemes?
I’m in a bit of a pickle and not sure how to go about this, any advice would be very much appreciated, I’ve attached a picture here to show what it looks like if that helps.

Here’s one way to do it, with a script – I don’t know whether this will help in your particular workflow, but it’s worth a look:

I hope one of these helps.

Hi Joseph,
Thanks for the reply.
I’ve checked out the sources you mentionned but for this particular setup and workflow, automated scripts will not work.
With the way my workflow is set up I will have to keyframe every phoneme which I don’t mind, the issue is just the transition, I could get away with it as it looks now but if I could blur thos lip movements somehow, the ‘smoothness’ of the lip transitions I’m looking for is something like this, so I guess I might have to blur the whole thing slightly?

You might try using frame blending, although it could look odd in 2D animation. Take a section of your mouth animation, precompose it, and turn on frame blending and see if that helps sell the effect.

Did you ever figure out a solution to this? I’m in a similar situation myself. I have phonemes in a precomp and am trying to use time remapping to cycle.

Sorry for the delay in response Brock.
I was advised to have each phoneme at 2 frames and just use time remapping, and to make sure to make the changes not below 2 frames i.e. don’t change lips every frame or it will look unnatural, does that make sense?.
It’s smoother in a different way now, it flows better I think.
