In this week’s lesson, we learned how to use CornerPin 2D. The CornerPin 2D node can be used to replace a picture somewhere in the motion picture. The purpose is to map the four corners of an image sequence to or from a position derived from tracking data. In fact, this node allows you to replace any four corner feature with another image sequence. For example, you can use it to place images on a TV screen. For the picture to be replaced in the picture, the Tracker node can be used to generate four tracks on the features to be replaced, one for each corner. Then export the information of the tracking node to CornerPin 2D and connect it to the replaced material.
