View or edit a keyframe value

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 is not 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 is not 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.
  • In layer bar mode, right-click (Windows) or Control-click (Mac OS) the keyframe. The keyframe value appears at the top of the context menu that appears. Choose Edit Value to edit the value, if desired.
  • Place the pointer over a keyframe in layer bar mode to see the time and value of the keyframe.
  • Click a keyframe to show information regarding its value, speed, and interpolation method in the Info panel. Different information is shown depending on whether the Timeline panel is in Graph Editor mode or layer bar mode.
    Note: When a keyframe is selected, You can also place the pointer over a keyframe or the curve between keyframes in the Graph Editor to see some of this information.
  • Alt-click (Windows) or Option-click (Mac OS) two keyframes in layer bar mode to display the duration between them in the Info panel.

Jeff Almasol provides a script on his redefinery website that creates new layer-time markers (either on the selected layer or on a new null layer) with comments that provide information about keyframes at the same times.
