How to Use the 3D Camera Tracker in After Effects

In this quick tutorial, you learn how to use 3d camera tracking in After Effects. This effect is useful for rendering images, videos, or graphics on top of an existing video with motion, so that your new asset looks proper in a 3D visual environment. The 3d camera tracker effect will make tracking points on your video layer after you analyze the footage. These tracking points will keep track of the motion of planes and lines to basically allow After Effects to understand the 3d motion of the environment. Once you track your video, you can then create a 3d camera and shape to follow the motion of the video, then simply replace the shape with your desired element, and you have manipulated 3d space within the program, something that would be nearly impossible without 3d camera tracking.
