Unlike other tracking solutions, you do not have to leave your compositor of choice in order to pull a track with Camera Tracker. This does away with the usual problem of finding formats that round trip correctly. Camera Tracker analyses a source sequence and lets you create an After Effects camera that matches how the original sequence was shot.
The three-step process seeds track points, models and solves the 3D feature positions of the track points, then creates an After Effects camera for the scene. Camera Tracker can be run fully automated, or you can use its incredibly in-depth configurable options to tweak everything from tracking and validation through to solving and object creation. The unique in-viewer menu featured in Camera Tracker allows for quick and easy operation of the plug-in without having to move the cursor, and thus your point of attention, away from the image itself.
The in-viewer menu and associated keyboard shortcuts allow you to create After Effects solids and nulls within your comp, positioned to match your currently selected tracked feature points. Easily tie objects and text within the context of your scene. Camera Tracker lets you configure a ground plane, thus setting the entire scene's orientation and offset via a variety of means that allow for rapid scene setup, allowing fine tooth control over the scene's offset and orientation, or manual tweaking.
Once a shot has been solved and a scene created, you can easily render a 3D feature preview, which details the positions of the individual feature points and their current selection and frame state. This unique feature can be used to visualize and assist in setting ground planes and creating objects.

This action does not have any visible result, but the reference plane and origin of the coordinate system are saved for this scene. Any items that you create from within this instance of the 3D Camera Tracker effect are created using this plane and origin.

If this option is on, when you delete track points in the Composition panel, corresponding track points for example, track points on the same feature or object are deleted at other times on the layer, so it isn't necessary to delete the track points frame by frame to improve the quality of the track.
For example, you can delete track points on a person running through the scene, whose motion should not be considered for the determination of how the camera was moving in the shot. This method works for both 2D Source and 3D Solved track points. You can delete selected track points with the Delete key or by context-clicking and choosing Delete Selected Points.
Even with the new Auto-delete Points Across Time feature, you can instead or additionally define an alpha channel for the layer to prevent the 3D Camera Tracker effect from considering a specific part of the image for determining a camera.
