2D Cleanup is an exercise for Week 9. For comparison and exercise, I added new nodes to the original file. The purpose of the cleanup is to combine previous roto and tracker nodes with other nodes to clean up the screen and add objects to the screen. After creating the CornerPin2D in the tracker node, add the text to the screen by copying and adding the text node to that node. The erase effect is implemented through RotoPaint. In this case, I can replace some objects in the frame with backgrounds by copying the brush. The Premult and FrameHold nodes then allow them to be mixed with pictures.
