The Brush tool
, Clone
Stamp tool
, and
Eraser tool
are
all paint tools. You use each in the Layer panel to apply paint
strokes to a layer. Each paint stroke’s brush marks add or remove
pixels from the layer or modify the layer’s transparency without
modifying the layer source.
Each paint stroke has its own duration bar, Stroke Options properties, and Transform properties, which you can see and modify in the Timeline panel. Each paint stroke is, by default, named for the tool that created it, with a number that indicates the order in which it was drawn.
At any time after you draw a paint stroke, you can modify and animate each of its properties using the same techniques that you use to modify a layer’s properties and duration. You can copy paint stroke path properties to and from properties for mask paths, shape layer paths, and motion paths. For even more power and flexibility, you can link these properties using expressions. (See Creating shapes and masks and Add, edit, and remove expressions.)
Individual brush marks are distributed along each paint stroke—though the marks may appear to merge together to form a continuous stroke with the default settings. Brush settings for each brush in the Brush Tips panel determine the shape, spacing, and other properties of brush marks; you can also modify these Stroke Options properties for each stroke in the Timeline panel.
Groups of paint strokes appear in the Timeline panel as instances of the Paint effect. Each instance of the Paint effect has a Paint On Transparent option. If you select this option, the layer source image and all effects that precede this instance of the Paint effect in the effect stacking order are ignored; the paint strokes are applied on a transparent layer.

For some painting, drawing, cloning,
and retouching tasks, you may want to take advantage of the sophisticated
paint tools provided by Adobe Photoshop. See Working with Photoshop and After Effects.
