Moving a mouth..

[Kevin Camp]

i’ve done something very similar… my mouth movement was a bit like the monty python jaw movement in their clipart animations, so the jaw just dropped 10-15 pixels at every sylable

first, i added markers to the speech layer every time i need the mouth to move.

then i just linked the jaw position to the markers with an expression… somehting like this:

if (t > thisComp.layer(“speech”).marker.nearestKey(time).time) {
value + [0,15];
} else {
value;
}

Select your audio source and use the keyframe assistant “Convert Audio to Keyframes”.
Check out the values this generates in the graph editor, we want to know the maximum value, in my case it was 5.

Now just pick-whip the mouth’s position to the created values;
you’ll get something like:

temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
[temp, temp]

change the second line to:

temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
value + [0,15]*temp/5;

so at the maximum audio amplitude (5), the mouth will be pushed down 15 pixels

that’s a cool trick…. unfortunately my audio was a song. if i ever have to do it again, i’ll see if they can get me the voice track separate from the music.
