After Effects Lesson, 1 2 and 4PT tracking

In this lesson we were taught on how to motion track for many different situations. This was similar to last weeks lesson however instead of last lesson the tracking was done by hand. The first tracking task that we had to perform was a 1 point track where we taught the basic functions in motion tacking and the end result made a humming bird flu across the screen.


The second part of the lesson was a 2 point track which involved a woman tilting her head, we were given the task to track black bars over the womans face to obscure her identity. This part has shown us why 2 point tracking is very useful as it covers the position as well as the rotation of the track. This was particularly difficult because of the way her head tilted back and it took a lot of by hand tracking to correctly track her eyes.



The next part of the lesson was a 4 point track which has been different from the last two portions of the lesson. We had to track an image onto a television where the camera was very shaky. This part of the lesson involved use of the perspective corner pin which gave us 4 cross hairs this time. The tricky part of this lesson was the placement of the crosshairs  as it needed to be placed in a very specific spot otherwise After Effects wouldn't be able to track the screen correctly. We were then given a short task to track a composition of our own to show our knowledge of the lesson. This is a useful tool that can be incorporated into our own indents.
