User Guide

5 In the Composition window, click a keyframe and drag the path to a new position.

Changing the number of visible motion-path keyframes

By default, After Effects displays motion path keyframes and dots in the Composition

window that fall within a 15-second range from the current-time marker. However, you

can change this default. For greater precision when extensively modifying a motion path,

you can display more keyframes. If you want to speed up screen updates, you can display

fewer keyframes.

To change the number of visible motion-path keyframes:

1 Choose Edit > Preferences > Display.

2 In the Motion Path section of the Display Preferences dialog box, select one of the

following options, and then click OK:

• Click No Motion Path to prevent the display of a motion path and its keyframes.

• Click All Keyframes to display every keyframe in the window.

• Click No More Than __ Keyframes to specify a maximum number of keyframes to

display, centered on the current-time marker.

• Click No More Than __ to specify a range of time within which keyframes display,

centered on the current-time marker.

Using Motion Sketch to draw a motion path

You can draw a path for the motion of a selected layer using Motion Sketch, which records

the position of the layer and the speed at which you draw. As you create the path, After

Effects generates a position keyframe at each frame, using the frame rate speciﬁed in the

composition.
