How do I track the motion of an object and then e.g. zoom in on said object, while keeping it in the center of the canvas?

Quick and dirty solution;

Right-click on the object that you want to track, choose Track Motion.

create a Null object. Layer > New > Null Object

in the Motion Tracking panel choose the Null as the Target for the Tracking.

In the Layer panel, select the area you want to track with the feature region. With the larger rectangle select the search area.

track the footage, the Apply the Tracking to the Null.

With the Null selected, Hit the U key to open the keyframes

copy the Tracking keyframes

paste them to the Anchor Point value of the video layer

make all layers 3D

create a two node camera - it's Point of Interest will automatically follow the Anchor Point of the video.

now simply animate the Zoom value of the camera to zoom in and out. Adjust or animate the position values of the camera to give you interesting angles.

Hope this helps,

Presumably you're simply looking for a basic 1-point stabilization using the classic 2D tracker. anything beyond that would require a better explanation and more info. there simply is not built-in way to e.g. pin a 3D track to its focal center when the footage has been shot wrongly. Correcting such stuff would require much more complex procedures.

We have no clue! We know nothing about the object you want to track nor the particulars of the shot... other than to say that any zoom in on bitmapped footage will get progressively crummy-looking.

What you need to do is not a tracking, you need a stabilization. The translation info will be applied to the anchor point of your layer, so you will have the position parameter free of keyframes to change the object position to the center of the scene
