This is me finishing the replacement of the phone screen.
Transform a super useful node that deals with translation, rotation, and scale as well as tracking,warping, and motion blur. In the middle of this session, we can make the colorwheel vary in size while in motion.
In this project, we’re replacing the TV screen, and first we need to track the four corners
After adding the tracking node, we need to bake the path and make the object that needs to be tracked and tracked bake it so that we can replace the previous background and get the result we want.
This picture is also learning how to replace and track
- First we’ll trace the four corners of the phone, then bake the path and trace it to completion.
Then I use the node roto to draw the mask, I need to do it in the first frame and in frame 80, because at this stage the hand will appear in the screen, after drawing the mask, the hand will not appear under the picture and the trace replacement screen is finished.
