  • Converting Audio to Keyframes (animating scale)

    using this expression:

    temp=thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”)*2;
    [temp,temp]

    How can I animate the vertical (Y) scale property only?

    thanks

    Like this:

    temp=thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”)*2;
    [value[0],temp]

    Using brackets like these:

    [X,Y,Z]

    You can control any individual dimension. I often use it for wiggling or 3D offset, EI:

    position=[0,0,index*20]

    index being the layer number in your timeline panel.
