After Effects Camera Tracker and Match Mover
CAMERATRACKER for After Effects® allows you to pull 3D
motion tracks and matchmoves without
having to leave AE. It analyses the source sequence and
extracts the original camera's lens and motion parameters,
allowing you to composite 2D or 3D elements correctly
with reference to the camera used to film the shot.
You can now match camera moves within Adobe® After
Effects® 2.5D environment, opening up new, robust
options for the placement of composite elements, such as
the creation of Fringe / Heroes style 'in scene' titles,
insertion of animated design elements, match-moved
virtual set extensions, motion-tracked projection mapping and much
This 3d motion tracking technology was previously only available in NUKEX, the Foundry's high-end film compositing tool.
You can now do all this in Adobe® After Effects® without exiting your application.
CAMERATRACKER: Motion Tracking in Action
In this sequence, Alexander Lehnert of Haus&Gross communications
demonstrates 3D camera tracking with CAMERATRACKER
inside After Effects®, exporting to Cinema 4D, projection mapping,
rendering, reimporting to After Effects® and comping. He
also shows the use of KRONOS retiming plug-in
to add visual impact to the shot's timing.

Alex demonstrates the use of CAMERATRACKER for After Effects to generate mask mattes quickly and easily,
and to insert text on to a scene element.
Core Tracking Workflow
CameraTracker analyses a source sequence
and allows creation of an After Effects camera, which matches that with
which the original sequence was shot. The basic process is 3 stages, namely:
- Track - automatically seeds a number of track points, based on a
series of user configurable parameters, and tracks them through the
sequence. The tracks are dropped and new ones are reseeded if they fall
below a certain quality threshold, and then are verified in a reverse
- Solve - Solve - builds a model of the 3d feature positions of the track
points, and the camera with which they were shot, based on the parallax
observed in a number of key frames, picked according to a series of user
- Create Scene - creates and After Effects camera and null which
embody the shot analysed. The null can be used to control overall scene
parameters, such as the scale, offset and rotation.
CameraTracker features a unique in viewer menu
which allows the user to interactively select a series of feature points
and create After Effect's Solids and Nulls at their location.
CameraTracker allows the user to configure a ground
plane, thus setting the entire scene's orientation and offset. This can
be additionally tweaked manually using the scene null.
Point Cloud Feature Preview
once a shot has been solved and a
scene created the user can flip the CameraTracker into rendering a 3d
feature preview. This details the positions of the individual feature
points, and their current selection and frame state. This can be used to
visualise and assist in setting ground planes and creating objects.
Stats Readouts & Refine Workflow
CameraTracker features a
comprehensive solve stats and refinement workflow. Parameters are
setting showing a number of useful statistics, both after the track
phase and the solve phase. Particular features can then be easily
isolated individually using the track finders, or deleting en masse
using the refinement thresholds and deletion functions.
- Lens Distortion - CameraTracker is able to estimate for and both
flatten and redistort lens distorted plates.
- Matting Workflow - to enable selective tracking for dealing with
more tricky shots.
- Powerful display functions - showing track and feature quality
measures both qualitatively and as an overview
- In-track display options - to allow the user to elect feedback or not
during the tracking process.
- Fully float image processing.
