Join Ian Robinson for an in-depth discussion in this video Creating 3D space from a 2D track, part of Mograph Techniques: Retiming and Tracking Footage.
We've successfully created a 2D track using the single point tracker in After…Effects. If you scrub through the project you'll…notice that we have a null object that's moving right through the scene.…Now I want to add z depth to this track. In order to do that, we need to create a…new null object. So I'm going to go up under the layer menu…and choose New null object. Now to reposition this null to follow…along with the track, let's hold down Shift on our keyboard and then click with…the Parent pick whip, and point it at layer 2.…
Now I want to draw a delineation between both of these null objects.…To do that, lets press S and change the scale of our child null to be…significantly smaller. I'll scale it down to around 40%.…Now this is going to be the null where we'll add 3D data.…So let's enable 3D for that layer. Now if we press P, we can open up our…position keyframes, and we'll go ahead and add a keyframe at the beginning and the…end of our track. I'm going to change the magnification of…my layer here, and move my current time indicator down towards the end of my…
