You can copy and paste most properties, including the Transform properties (such as Position and Opacity), Material Options properties, and
motion trackers.
You can use the motion tracking tools to track the motion of an object in a layer, and then paste the tracker data into a spreadsheet to perform
numerical analysis on the data.
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.
1. In the Timeline panel, select keyframes for one or more properties on the same layer. To select all keyframes for a property, click the name
of the property.
2. Move the current-time indicator to the first selected keyframe.
Place a composition marker at the time of the first selected keyframe so that you will know where to paste the modified keyframes in the
last step. (See Layer markers and composition markers.)
3. With the keyframes selected, choose Edit > Copy.
4. Paste keyframe data into the spreadsheet. Assuming that the first column in the spreadsheet is labeled A and the first row is labeled 1, you
should paste into cell A1. Frame numbers appear in column B. Property values appear in columns C, D, and E, depending on the
dimensions of the property. (Position in a 3D layer has values in all three columns; Opacity has only a value in column C.)
5. Edit the numerical information for the keyframes. Do not change any text other than frame numbers and property values.
6. Select the cells that contain your data. The top-left cell in your selection should be A1. The bottom row of your selection should be the row
that contains the text End of Keyframe Data.
7. Copy the data from the spreadsheet.
8. In After Effects, move the current-time indicator to the time at which you want to paste the new keyframe data. This time is usually the time
of the first keyframe that you selected and copied at the beginning of this procedure.
9. Choose Edit > Paste.
Move keyframes in time
You can move keyframes in time, either individually or as a group.
Jeff Almasol provides a versatile script on his
—layer In point, layer Out point, layer source frames, keyframes, and markers.
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.
1. Select one or more keyframes.
2. Drag any of the selected keyframe icons to the desired time. If you selected multiple keyframes, then all of the selected keyframes maintain
their relative distance from the keyframe that you drag.
You can also move selected keyframes in time (one frame earlier or later) by pressing the Alt (Windows) or Option (Mac OS) key with the left
arrow or right arrow key.
Move a keyframe to a specific time
1. Move the current-time indicator to the desired time.
2. Do one of the following:
In layer bar mode, hold down Shift after you begin to drag a keyframe icon to the current-time indicator.
In Graph Editor mode, drag a keyframe to the current-time indicator.
When you drag over the current-time indicator, the keyframe snaps to the current-time indicator.
Expand or contract a group of keyframes in layer bar mode
1. Select at least three keyframes.
2. Hold down Alt (Windows) or Option (Mac OS) and drag the first or last selected keyframe to the desired time.
Move a layer duration bar but not its keyframes
1. Place a composition marker at the time at which the first keyframe appears. (See Composition markers.)
2. In the layer outline, click the name of one or more layer properties containing the keyframes you want to keep at the same times.
3. Choose Edit > Cut.
