Work with clone presets
Use clone presets to save and reuse clone source settings: Source Layer, Aligned, Lock Source Time, Source Time
Shift, Offset, and Source Position values. Clone presets are saved in the preferences file, so they can be reused in other
projects. To work with clone presets, you must first select the Clone Stamp tool.
• To select a clone preset, press 3, 4, 5, 6, or 7 on the main keyboard, or click a Clone Preset button
Tips panel.
• To modify a clone preset, select it and adjust the Clone Options settings as desired.
• To copy the settings from one clone preset to another, select the clone preset from which to copy, and Alt-click
(Windows) or Option-click (Mac OS) the Clone Preset button for the clone preset to which you want to paste the
settings.
Use the Eraser tool
If you use the Eraser tool in Layer Source & Paint or Paint Only mode, it creates Eraser strokes that can be modified
and animated. In contrast, using the Eraser tool in Last Stroke Only mode only affects the last paint stroke drawn
and does not create an Eraser stroke.
To temporarily use the Eraser tool in Last Stroke Only mode, Ctrl+Shift-drag (Windows) or Command+Shift-drag
(Mac OS).
Select the Eraser tool from the Tools panel.
1
2 Choose settings in the Paint panel.
Select a brush in the Brush Tips panel, and set brush options.
3
4 Drag through the area you want to erase in the Layer panel.
Each time you release the mouse button, you stop drawing a stroke. When you drag again, you create a new stroke.
Shift-drag to resume drawing the previous stroke.
Note: If you use a graphics tablet, pressing the eraser side of the pen to the tablet temporarily activates the Eraser tool.

Animate paint strokes
You animate a paint stroke by setting keyframes or expressions for its properties. After Effects animates paint stroke
properties—even the paint stroke's Path property—by interpolating values for all frames between keyframes.
By modifying and animating a paint stroke's Start and End properties, you can control how much of a stroke is shown
at any time. For example, by automatically animating the End property from 0% to 100% with the Write On setting,
you can make a paint stroke appear to be drawn on over time.
As with all properties, you can link paint stroke properties to other properties using expressions. For example, you
can make a paint stroke follow a moving element in your footage by tracking the moving element and then linking
the paint stroke's Position property to the tracker's Attach Point property.
