Scale expression – Could someone help please?

[Filip Vandueren]

you could try remapping the 0-100% values of the keyframes to 100-120 like this:

(add to the allready keyframed scale):

s=value[0];
linear(s,0,100,100,120);
[s,s];


If you just want to cycle the values between 100 and 120 every 15 frames, try this:


t=timeToFrames(time);

t=t%45; // this will loop every 45 frames:

if (t<15) {
s=ease(t,0,15,100,120);
} else if (t<30) {
s=120;
} else {
s=ease(t,30,45,120,100);
}
[s,s];


Those eases can be switched with linear or easeIn or easeOut

temp = thisComp.layer("Black Solid 1").effect("Sound Keys")("Output 1");
[temp, temp]

Thanks Filip for your response,

What you’re saying is kind of working but I can’t seem to get it to work with Trapcode Sound Keys.

I’m linking the sound keys layer to the footage layer ‘scale’ and sound keys is doing it’s job by scaling on the beat but not the way I want it to.

I think I need sound keys support/help. After I link the sound keys layer to my scale parameter,it generates the following expression that I have posted above.

What I want is scale 110% then 100%, then 110% then 100% on each music beat controlled by the sound keys layer.

By the look of the expression I posted, does it seem that I need to edit the expression below to get what I want or with sound keys?

Where would you say the answer lies, the scale layer or sound keys?

It’s cool I fixed it!.

The solution was in the Plugin – Setting a custom output range.

Thanks again for your help.
