  Link parameter to time?

  Posted by Noel Powell on May 19, 2012 at 6:11 am

  Hi, I’m wondering if there’s an expression to continuously change a parameter without using keyframes and without the parameter ever repeating the same value (so the wiggle expression is out). The parameter I want to change is the evolution of a Fractal Noise effect. It needs to steadily increase in a linear fashion (not randomly) – so I guess eventually, it would have to loop, since it only goes up to 90 360-degree revolutions or something. Is there maybe a way to link the evolution to the comp’s time code value?
  Thank you!

  Something like this should work:

  rate = 50; // degrees per second
  rate*time
