  • Simple Rate Scale Up and Down Expression

    Posted by Conor Gordon on October 28, 2014 at 12:48 am

    I’m looking for an expression that will indefinitely scale up or down a still at a constant rate. I am working with many different sizes of images, so I need the expression to be relative.

    Also, could such expression also be easily edited to apply to position as well?

    Thanks!

    for scale I think you can go with:

    t=time - thisLayer.inPoint;
    rate=1;
    c=(value*rate)*t
    value+c;

    It will double the layer’s scale every second, change “rate=1” for adjustments. You can do something like that to its position too, but it will depend on how you want it to behave.
