In this session, we have learned 2D tracking. It is a simple way for us to add an image or video into another shot.
The new node:
Track node can help us to extract animation data from the shots. Then we can apply the data directly to transform and match-move another element. If the object which you have added into the shot starts skewing weirdly, we should change the different point. Before you tracking, do not forget to set the reference frame.
In addition, we should denoise the original footage before we start tracking. This step can make tracking data more accurate.
Transform, Rotation, Scale, Translation, and crop. These nodes are used to adjust the images, which can make the new element looks more reasonable.
