Corner Pin effect

The Corner Pin effect distorts an image by repositioning each of its four corners. Use it to stretch, shrink, skew, or twist an image or to simulate perspective or movement that pivots from the edge of a layer, such as a door opening. You can also use it to attach a layer to a moving rectangular region tracked by the motion tracker. You can move the corner pins in the Composition panel, the Timeline panel, or the Effect Controls panel.

This effect works with 8-bpc, 16-bpc, and 32-bpc color.

This post on the AE Enhancers forum describes and links to an animation preset from Donat van Bellinghen for scaling a set of Corner Pin effect points: www.adobe.com/go/learn_ae_donatscalecornerpin.

RE:Map from RE:Vision Effects has a corner pin that adds more
functionality than AE's built in corner pinning (of course RE:Map has
several plugins in which corner pinning is just one plugin). What's added?
* Higher quality filtering
* ability to use the 4 corner points to define a plane, but then extend the
textured image past the 4 corner points in true 3D
* inverse corner pinning feature that allows you to warp a perspective plane
from an image to an undistorted space to be edited, or applied elsewhere
as a texture
