Limiting Expressions
I am linking the scale of a Layer, to the audio keyframes of my soundtrack. I know how to do this, by dragging the pick whip of my Expression.
Now I want the Scale expression not to go below or above certain dimensions (let’s say the scale fo the layer shouldn’t go below 25%, and not above 200%).
Unfortunately i am not very good at writing expressions, what do I need to add to the expression that looks like this, in order to limit the scale?:
temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
[temp, temp]thanks,

Use something like this:
min_audio=0; //minimum audio amplitude
max_audio=10; //maximum audio amplitude
min_scale=25; //minimum allowed scale
max_scale=90 //maximum allowed scaledriver=thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
result=linear(driver,min_audio,max_audio,min_scale,max_scale);
[result,result]
