Reverse Corner Pin

Reverse Corner Pin is a tool for removing perspective from a shot. It stretches a perspective area defined by four “pins” into a rectangle. Use it to straighten rectangular images that were photographed askew.

Sometimes we have a shot that we want to flop or mirror in our edit, but there is a sign in the background that would look bad with reversed text. Reverse Corner Pin can also flip the pinned area while preserving its perspective, allowing you to flop the shot without the backwards text problem.

Reverse Corner Pin works best on still images or static shots, but the pins can be keyframed, or linked to tracking points in After Effects to flop shots with camera motion.

Usage

Outline the area to be stretched by dragging the pins from the corners of the shot to the corners of the desired area. Then change the “Stretch Mode” to stretch the area into a rectangle, or mirror the area while maintaining its perspective.
