Projection makes light work of camera mapping onto 3D planes in After Effects. It was created with the release of After Effects CS6 in mind, which now has the 3D Camera Tracker, a built-in matchmover. But Projection works equally well with imported match-move data from programs such as Syntheyes, Boujou and PF Track.
Projection makes a variety of compositing tasks much easier. Once arduous tasks, like floor replacements, tracking mark removal and set-extensions are made much easier with Projection.
Projection – 3D Camera Mapping for After Effects
By projecting the camera’s view onto a match-moved surface, Projection effectively creates a plate from a moving shot – a static overhead view of part of the moving image. That makes altering that part of the image child’s play. For instance, tracking marks in a shot can now be removed with a single quick paint stroke, taking seconds instead of hours.
