Choose a disposal method

The frame disposal method specifies whether to discard the current frame before displaying the next frame. You select a disposal method for animations that include background transparency to specify whether the current frame will be visible through the transparent areas of the next frame.

Frame disposal methods

A.
Frame with background transparency with Restore To Background option

B.
Frame with background transparency with Do Not Dispose option

The Disposal Method icon indicates whether the frame is set to Do Not Dispose  or Restore To Background . (No icon appears when Disposal Method is set to Automatic.)

  1. (Photoshop Extended) Make sure the Animation palette is in frame animation mode.
  2. Select a frame or frames for which you want to choose a disposal method.
  3. Right-click (Windows) or Control-click (Mac OS) the frame thumbnail to view the Disposal Method context menu.
  4. Choose a disposal method:
    Automatic
    Determines a disposal method for the current frame automatically, discarding the current frame if the next frame contains layer transparency. For most animations, the Automatic option (default) yields the desired results.
    Note: To enable Photoshop to preserve frames that include transparency, select the Automatic disposal option when you are using the Redundant Pixel Removal optimization option.

    Do Not Dispose
    Preserves the current frame as the next frame is added to the display. The current frame (and preceding frames) may show through transparent areas of the next frame. Use a browser to see an accurate preview of an animation using the Do Not Dispose option.

    Dispose (Photoshop)
    Discards the current frame from the display before the next frame is displayed. Only a single frame is displayed at any time (and the current frame does not appear through the transparent areas of the next frame).
