An earthquake is a more complicated process than a stone splashing into water, and the seismic waves that are set up during an earthquake are more varied than those on the pond. You can picture this concept by recalling the circular waves that spread over the surface of a pond when a stone is thrown into the water. Seismic waves are propagating vibrations that carry energy from the source of the shaking outward in all directions. Remember to customize the frequency and amplitude values to suit your specific needs.When you look at a seismogram the wiggles you see are an indication that the ground is being, or was, vibrated by seismic waves. Preview the animation by pressing the Spacebar or using the RAM Preview option (Ctrl/Cmd + 0).īy using the wiggle expression, you can add organic, natural-looking movement to your compositions and save time compared to manually keyframing animations.You can experiment with different values until you get the motion or animation you want. Adjust the frequency and amplitude values to achieve the desired effect.After releasing the pick whip, add wiggle(frequency, amplitude) to the end of the expression.Move your cursor to the timeline panel and click and drag the pick whip (the spiral icon) to the position property of a null object or another layer that you want to control the wiggle.
Option 2: Apply the expression using the pick whip: Press the Enter key to apply the expression.For example, if you want it to move by 50 pixels, use 50. Replace “amplitude” with a number that represents how much you want the property to move or change.For example, if you want it to wiggle three times per second, use 3. Replace “frequency” with a number that represents how many times per second you want the property to wiggle.In the Expression Editor, type the following code: wiggle(frequency, amplitude).Hold down the Alt key (Windows) or Option key (Mac) and click on the stopwatch icon next to the property you want to apply the expression to.Option 1: Apply the expression directly:.Press the “P” key to reveal the position property, or use the appropriate keyboard shortcut for the property you want to apply the expression to.Select the layer or property you want to apply the wiggle expression to.Here’s how you can use the wiggle expression in After Effects: It can be applied to various properties such as position, rotation, scale, opacity, and more. The wiggle expression in Adobe After Effects is a powerful tool that allows you to create random movement or animation in your compositions. How to use wiggle expression in after effects
