Layered photo pop-up

A common technique in documentaries is to animate photographs by panning across them slowly. More recently, it has become popular to divide such photographs into layers, and to animate these layers as moving over each other to create a motion parallax effect, commonly known as the "3D Ken Burns effect". Producing this effect involves a laborious manual process that requires hours of manual rotoscoping, clone-brushing, positioning in 3D, and adjusting the panning speeds of individual layers.
