Mouth/Jaw Movement Using Audio Amplitude
Hello!
I´m making a 8-bit animation on after effects, and I´m using this expression, so the mouth of my character moves on Y according to the audio amplitude.
temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”) ;
[position[0], position[1] + temp]1. I want to know if there´s an expression so I can limit the value of temp. I want it to have a maximum value of 30, so if it is more than 30, it keeps on 30, this way the jaw of my character doesn´t move more than the size of his face.
2. I also need another expression, so i can see what´s the best option. I want the jaw to move 0 a temp is < 5 , and I want it to move directly to 30 if the temp value is > 5.
Thanks!

For the first part of your question, limiting the value, you could change your expressions thus:
temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”) ;
if (temp > 30) {
temp=30;
}
[position[0], position[1] + temp];For the second part, making your values jump you could try:
temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”) ;
if (temp <= 5) {
temp=0;
} else {
temp = 30;
}
[position[0], position[1] + temp];Declan Smith
