right of the Offset button. To set an offset location, click the Offset button, and then click the image in the desired location. To set the offset
position numerically, type a new value for each axis. When you don’t need the precision provided by Mask Offset, you can simply drag the source
mask offset in the Composition panel.
Unwanted undulations may occur if the source mask is close to the boundary mask during animation.
Rotates the source mask around its center point, between 0° and 360°.
Scales the source mask (at its offset position) larger or smaller, in relation to its original position.
Specifies what percentage of the smear is performed. For example, when Percent is set to 50%, Smear performs half of the smear you
have specified by moving, scaling, and rotating the source mask. This value doesn’t affect the location of the original and offset positions of the
source mask; it affects only the percentage of the effect that is performed.
Specifies how closely the image follows the shape defined by the curve. Stiff distorts the least, while Super Fluid distorts the most. In
general, use the stiffest setting possible that doesn’t create polygonal images.
Specifies a method for the interpolation that Smear performs between keyframes. Linear requires two or more keyframes
and performs a straight-line interpolation between the keyframes. Discrete produces animations in which the distortions change at keyframes.
Smooth requires three or more keyframes and approximates the distortion using cubic curves, producing distortions with graceful motion. If you
need further precision in the animation between keyframes, add more keyframes. For example, a distortion representing a 90-degree rotation
between two keyframes appears as a folding of the image. To make this distortion more fluid, add a keyframe for every 10°.
Use the Smear effect
1. Open the layer in a Layer panel.
2. Create or paste the masks to use as the boundary mask and the source mask.
3. Position the boundary mask to specify the area of the layer you don’t want Smear to affect.
4. Scale and position the source mask over the area you want to move.
5. Make the Composition panel active, and choose Effect > Distort > Smear.
6. Enter a Percent value to specify the amount of smear applied.
7. In the Composition panel, move the source mask to its destination position by dragging it or by using the Mask Offset value.
8. Use the Mask Rotation control to rotate the source mask, and use the Mask Scale control to scale it.
9. Drag the Percent slider as needed, and choose a setting for Elasticity.
Spherize effect
The Spherize effect distorts a layer by wrapping a region of the image onto a sphere. The quality setting of the layer influences the Spherize
effect. Best quality samples the displaced pixels to subpixel precision; Draft quality samples to the nearest whole pixel.
This effect works with 8-bpc and 16-bpc color.
