Animation and layer properties
About animation and layer properties
Animation is the creation of change over time. You can animate different layer properties, such as position, rotation,
masks, and effects, with endless possibilities for creativity. Each change can occur independently of, and yet simul-
taneously with, other changes.
Each layer can contain many sets of properties. Layers that contain video or still images have mask and transform
properties,suchasmaskshapeandlayerrotation.Alayercanalsoincludeotherproperties,suchastimeremapping,
video effects, and audio effects.
Here are some examples of how you can animate layer properties:
• You can animate position by adding keyframes to the Position property and dragging the layer in the Composition
panel. For example, you can move a layer by selecting it at its existing position and then dragging it 10 pixels to
the left.
• You can animate a layer property by adding keyframes to the property and dragging the underlined property
value. For example, you can change a layer’s opacity by dragging its underlined Opacity value.
• You can animate a layer property by adding keyframes to the property and entering an absolute number for the
property’s value. For example, you can move a layer by typing new coordinate values for the Position property.
• You can animate layer properties by moving keyframe positions in the Graph Editor. For example, to decrease the
size of a layer, drag a keyframe for the Scale layer property to a lower position in the Graph Editor.
• You can animate a layer property by adding an expression to the property.
• You can animate a layer by applying an animation preset.

About the Graph Editor
To view and manipulate all aspects of effects and animations, including effect property values, keyframes, and inter-
polation, use the Graph Editor. The Graph Editor represents changes in effects and animations as a two-dimensional
graph, with playback time represented horizontally (from left to right). In layer bar mode, on the other hand, the
time graph represents only the horizontal time element, without showing a visual representation of changing values.
There are two types of graphs available in the Graph Editor: value graphs, which show property values; and speed
graphs, which show rates of change of property values.
