Editing, moving, and copying keyframes

Before you change a keyframe, make sure that the Current Time Indicator is positioned at an existing keyframe. If you change a property value when the Current Time Indicator isn't at an existing keyframe, After Effects adds a new keyframe. However, if you double-click a keyframe to modify it, the current-time indicator location isn't relevant, nor is it relevant when you change the interpolation method of a keyframe.

• Move the Current Time Indicator to the time of the keyframe. The value of the property appears next to the property name, where you can edit it.
• Right-click (Windows) or Control-click (macOS) the keyframe. The keyframe value appears at the beginning of the context menu that appears. Choose Edit Value to edit the value, if desired.
• Place the pointer over a keyframe in the layer bar view to see the time and value of the keyframe.
• Place the pointer over a keyframe in Graph Editor mode to view the keyframe's layer name, property name, time, and value. Place the pointer over a segment between keyframes to view the corresponding information at any time.
• Select a keyframe in layer bar mode to show the keyframe's time and interpolation method in the Info panel.
• Select a keyframe or segment between keyframes in Graph Editor mode to show a property's minimum and maximum values and the speed at the current time in the Info panel.
• Alt-click (Windows) or Option-click (macOS) two keyframes in layer bar mode to display the duration between them in the Info panel.

Copy and paste keyframes

Copy and paste keyframe selections that span multiple layers without creating additional layers.

You can copy keyframes either from a single layer or across multiple layers. When you paste keyframes into another layer, they appear in the corresponding property in the destination layer. The earliest keyframe appears at the current time, and the other keyframes follow in relative order. The keyframes remain selected after pasting, so you can immediately move them to the destination layer.

You can copy keyframes between layers for the same property, such as Position, or between different properties that use the same type of data, such as between Position and Anchor Point.

Reverse paste selected keyframes

You can also copy existing keyframes spanning multiple layers and reverse paste them to reverse the time of placement. This reuse of the same animation keyframes but in the opposite direction allows you to create animations with repetitive patterns, such as loops, bounces, and rewinds, without starting from scratch.

Edit keyframe values using a spreadsheet or text editor

You can copy and paste keyframe data as tab-delimited text for use in a spreadsheet program, such as Microsoft Excel or other text-editing programs. You can use a spreadsheet program to perform numerical analysis on keyframe data or create or edit keyframe values.

You can copy and paste most properties, including the Transform properties, such as Position and Opacity, Material Options properties, and motion trackers.

Some utility applications, such as Imagineer Systems mocha for After Effects (mocha-AE), copy keyframe data to the clipboard so that you can paste it into the appropriate layer in After Effects.

You can copy keyframes from only one layer at a time as tab-delimited text.

Move keyframes in time

You can move keyframes in time, either individually or as a group.

Move keyframes to another time

With multiple keyframes selected, you can copy or delete them simultaneously or move the keyframes together without changing their positions relative to each other.

Move a keyframe to a specific time

Expand or contract a group of keyframes in layer bar mode

Move a layer duration bar but not its keyframes

Change multiple keyframe values at once

You can change the values of multiple keyframes on multiple layers at one time. However, all keyframes you select must belong to the same layer property. The way the selected values change depends on the method you use to make the change.

• If you change a value numerically, all selected keyframes use the new value exactly. In other words, you make an absolute change. For example, if you select several Position keyframes on a motion path and numerically specify a Position value for one of them, all selected keyframes change to the same position value.

• If you change a value by dragging the underlined value, all selected keyframes change by the same amount. In other words, you make a relative change. For example, if you select several Position keyframes on a motion path and drag the underlined value for one of them, all selected keyframe values change by the same amount.

• If you change a value graphically in the Composition or Layer panel, all selected keyframes change using the difference between the old and new values, not the values themselves. In other words, you make a relative change. For example, if you select several Position keyframes on a motion path and then drag one of them 10 pixels to the left, they all move 10 pixels to the left of their original positions.

You can also change the value of several layers at once in layer bar mode by parenting them.

Move or change keyframes in the Graph Editor

A value graph in the Graph Editor displays the values for each keyframe and the interpolated values between keyframes. When the value graph of a layer property is level, the value of the property is unchanged between keyframes. When the value graph goes up or down, the value of a layer property increases or decreases between keyframes.

You can change layer property values by moving the points (keyframes) on the value graph up or down. For example, you can increase the value of a Rotation keyframe by dragging the keyframe marker on the Rotation property’s value graph higher up on the graph.

Modify a single keyframe in the Graph Editor

Modify multiple keyframes in the Graph Editor

You can edit and move multiple keyframes simultaneously using the Graph Editor. When you select multiple keyframes with the Show Transform Box button selected, a free-transform bounding box surrounds the selected keyframes, and an anchor point appears in the center of the bounding box to mark the center point for the transformation. You can move the selected keyframes in time or value by dragging the bounding box or its handles. You can also change the position of the anchor point.

Adjusting a free-transform bounding box in a value graph moves the selected keyframes in time and value. Adjusting a free-transform bounding box in a speed graph moves the selected keyframes in time only.
