Type Wiggle (3,8) and adjust the settings as. When you see the position text turn red and begin. Pressing the alt/option key, click the stopwatch beside position. For this example, I have an image of pancakes and.

Using a continuous wavelet transform, the wavelet Gibbs phenomenon never exceeds the Fourier Gibbs phenomenon. In your after effects file, select the layer that you want to shake. In practice, the difficulties associated with the Gibbs phenomenon can be ameliorated by using a smoother method of Fourier series summation, such as Fejér summation or Riesz summation, or by using sigma-approximation. Extending After Effects with Expressions Looping Wiggle Expression freq Maintain Scale when Parented s Maintain Stroke Width value / Loop In and Out. See Convergence of Fourier series § Absolute convergence. By the same token, it is impossible for a discontinuous function to have absolutely convergent Fourier coefficients, since the function would thus be the uniform limit of continuous functions and therefore be continuous, a contradiction. This only provides a partial explanation of the Gibbs phenomenon, since Fourier series with absolutely convergent Fourier coefficients would be uniformly convergent by the Weierstrass M-test and would thus be unable to exhibit the above oscillatory behavior. Wiggle X and Y seperately: wiggle (5,30) 0,wiggle (1,100) 1 You can tie any of the above to sliders, highlight the 1 in the first expression and pickwhip to a slider stopwatch (after you use, Effect>Expression Controls>Slider Control, then name it Y Frequency), then the slider controls that number (Frequency 1st number.

Where x is equal to the frequency (amount of wiggles per second) and y is equal to the amplitude (how much it wiggles). You can play with the frequency and amplitude values, and it can be applied to any keyframeable property. In mathematics, the Gibbs phenomenon is the oscillatory behavior of the Fourier series of a piecewise continuously differentiable periodic function around a jump discontinuity. Take your 2 keyframes, select them and then apply the wiggler.
