# Motion Update

When you play or scroll the clip in the image window, the image is updated to reflect any animation of the properties of the key. You can disable this default by disabling the Motion Update button in the Setup menu. When disabled, the image window is not updated to reflect keyed parameters.

Disabling Motion Update is useful for copying keyframe values from one frame to another. See Copying and Pasting Channels or Keyframes.
