Ghosts let you see how an animation moves through a scene. Unlike Motion Trails, which simply use a line to illustrate where an animated object moves, a ghosted object shows a semi-transparent representation of the object at the points in time you specify. Cached playback lets you ghost deformed meshes, and improves the speed of playback.
The opacity and the color of ghosts make it easy to differentiate between the individual frames of your animation. By default, the opacity gradient ramps down linearly from the ghost closest to the current frame to the ghost farthest away. You can adjust the ghost opacity and color using options in the Ghosting Editor.
