1. Open the layer in a Layer panel.
2. Create or import the source, destination, and boundary masks into the layer.
Name each mask so that you can easily recognize it in the Mask menu in the Effect Controls panel.
3. In the Timeline panel, choose None from the Mode menu for each mask.
4. Position the boundary mask to specify the area of the image that will remain unaltered. Areas within the boundary mask are distorted; areas
outside the mask remain unaltered. Keep the boundary mask as far as possible from the source and destination masks to avoid foldovers.
5. Scale and position the source mask over the image.
6. Scale and position the destination mask to indicate the final shape. Distortions work best if the source and destination masks are in
approximately the same location.
7. Make the Composition or Timeline panel active, select the layer, and then choose Effect > Distort > Reshape.
8. From the Mask menus, choose the source, destination, and boundary masks.
9. Adjust the Percent control, and choose an option for Elasticity.
10. In the Composition panel, add, delete, or move correspondence points on the masks to control the distortion:
To add a point, Alt-click (Windows) or Option-click (Mac OS) the mask.
To delete a point, Alt-click or Option-click the point.
To move a point, drag it to a new location.
To change the interpolation of a pair of points, Shift-click a point. Smooth interpolation works best with round masks, while linear
interpolation works best with angular masks. You can combine smooth and linear interpolation in the same composition.
11. Choose an interpolation method, and preview the distortion. If Linear or Smooth produces undesired results, add more keyframes. If Discrete
produces undesired results, choose another method.
Ripple effect
The Ripple effect creates the appearance of ripples in a specified layer, moving away from a center point in concentric circles. The effect is similar
to dropping a stone in a pond. You can also specify that ripples move toward the center point.
Animate ripples at a constant speed using the Wave Speed control. This control doesn’t require keyframes for animation. Animate ripples at
varying speeds by creating keyframes for the Ripple Phase control.
This effect works with 8-bpc and 16-bpc color.
Radius Controls the distance the ripples travel from the center point. The Radius value is a percentage of the image size. If the center of the
ripple is the center of the layer and the radius is set to 100, the ripples travel to the edge of the image. A value of 0 produces no ripples. Like
ripples in water, ripples in the layer become smaller as they travel farther from the center.
To create a single-wave ripple, set Radius to 100, Wave Width to a value in the range from 90 to 100, and Wave Height as desired.
Center Of Ripple Specifies the center of the effect.
Type Of Conversion Specifies how the ripples are created. Asymmetric produces more realistic-looking ripples; asymmetric ripples include lateral
motion and produce more distortion. Symmetric produces motion that travels only outward from the center point; symmetric ripples produce less
distortion.
Wave Speed Sets the speed at which the ripples travel outward from the center point. When you specify a wave speed, the ripples are
automatically animated at a constant speed (without keyframes) across the time range. A negative value makes the ripples move toward the
center, and a value of 0 produces no movement. To vary wave speed over time, set this control to 0, and then create a keyframe for the Ripple
Phase property of the layer.
Wave Width Specifies the distance, in pixels, between wave peaks. Higher values produce long, undulating ripples, and low values produce many
small ripples.
Wave Height Specifies the height of the ripple wave. Taller waves produce greater distortion.
Ripple Phase Specifies the point along the waveform at which a wave cycle begins. The default value of 0° starts the wave at the midpoint of its
downward slope; 90° starts it at the lowest point in the trough; 180° starts it at the midpoint of the upward slope, and so on.
Smear effect
Using the Smear effect, you define an area within an image and then move that area to a new location, stretching, or smearing, the surrounding
part of the image with it. Use masks to define the area you want to distort.
This effect works with 8-bpc and 16-bpc color.
To use Smear, first create or import two masks: the source mask and the boundary mask. You can create masks on the layer in After Effects or
use masks created in Adobe Illustrator. To use a mask created in Illustrator, copy the mask and paste it into a layer in After Effects. Masks must
be closed to work with Smear; if a mask is an open trace, After Effects closes it when you select it. Both masks must be on the same layer as the
footage to which you apply the Smear effect, although you can copy masks from another layer.
When you move the source mask within the image, Smear stretches the portion of the image inside the boundary mask to follow the edges of the
source mask. The boundary mask tries to protect the image outside it from being stretched. Both the original position of the source mask (set in
