This week we learned about planar tracking, first, we learned how to arrange the nodes correctly. Due to the different order of arrangement may produce different results.

Next, we learned about Shuffler Node, we can change the channels of RGB by Shuffler Node. We can rearrange the different color channels of a texture to the nodes of other color channels.

After that, we started to learn plane tracking. We used Planar tracker, which works very well. It helps us to change and replace images easily. We first roto the area we want to replace and track it. Then we use display_planar_surface and display_grid_lines to adjust our selected area. Finally, we replace our image with CornerPin.

Finally, we also learned about the Defocus and ZBlur nodes. These two nodes can change the focus position. Thus, area blurring is performed. This is very useful in video editing.
