Simple "pixel style" mouth animation
on Jan 6, 2017 at 1:32:19 pm

Hello, first post here, I'm trying to transition to AE from Moho because I find Moho too buggy and inconsistent.

I do pixel-art style animation where a character's mouth is just alternating rectangle shapes with different colours. One for mouth open, one for closed. My goal is to animate this automatically using the .wav dialogue file. In Moho I had a switch layer where I would manually select the mouth based on the audio, which is tedious.

I've been trying to experiment with a two-valued slider that would be at either 0 (mouth closed shape) or 1 (mouth open) depending on the amplitude of the audio waveform but I can't get it to work.

But then I thought maybe there's an easier way to do this. Like have a square shape in AE that changes opacity based on the amplitude.

I'm coming at this from a life of no scripting so I'm struggling to think more like a programmer.

Any suggestions on how to solve this, I'm sure, simple problem would be much appreciated.

Hi Magnus, snap this is my first post too.

But hopefully this will help, and its a script called AutoLypSync I tried it today since I needed to do he same thing.
It's pretty straight forward and basically steps you through the process, have to say it does a pretty good job.

I downloaded a trial from and costs about $40

Great, thanks. For now I've solved it simply by connecting the open_mouth image opacity value to the keyframe slider created from the audio waveform. That way it blinks in sync with the dialogue which look pixel-tacky enough for my purposes.
