How to track and zoom in AE

Question

I want to learn how to make the effect that is presented in the video from 0:29 to 0:31, that is, cursor tracking and zoom.

Answer 1

Here is how I would do it:

• Track the cursor in After-Effects (using the tracking-panel)
• Apply the movement to a Null-Object
• Create a camera
• Parent the camera to the Null
• Change the focal length in the camera to achieve the zoom

Now your camera should follow the cursor.
