lip sync vertical position changes
I am trying to do a lip sync, I have written down all the instructions very precisely, The process uses the puppet tool pick whipped to the slider in my audio file.
It worked great the other day, my dilemma is that when the vertical position # goes red it changes, this in turn also changes the position of my subject, I also tried by not using the puppet tool and just going to the layer and pick whipping from position, the same thing happens.
Is there a way of pre-setting the vertical axis key so that it will keep the # one wants to use?
Tks

Please post the expression you’re using.

It might be that this is all you need:
temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
value + [0, temp]If you need the pin to go up instead of down, change the “+” to a “-” in the last line.

amp = +.06;
temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
value + [0,temp*amp]It’s a bottom lip going down, I start off with the vertical at 562 and it immediately changes to 584 I then moved forward a keyframe create new key at 562 it then goes to 584!!

Are you saying that the y changes from 562 to 584 when you apply the expression? That would mean that the audio amplitude would have to be 367 at that time. That seems awfully high. I think something else is going on.

Dan,
You were 100% on the ball when you gave me the answer in a similar thread, your response was:
amp = -.4;
temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
value + [0,temp*amp]Being a beginner I misinterpreted what I saw i.e. After I set in the expression, (above) I saw the bottom lip rise high above the face and thought I should change the – for a +. I was incorrect, I should have just brought the lip down with the vertical control, it’s working fine now, I have 63 animated mates in sync.
now I have to learn how to fine tune the lip movements through the audio, if that’s possible!!
anyway Dan, tks mate
