3D Camera Tracker is a plug-in for Adobe After Effect (CS4 or after). You can use 3D Camera Tracker to make camera tracking in one shot. It supports the existing Camera and Point Light.
The first thing you should know about this plugin is that it is for 3D tracking and not for 2D tracking. If you want to track 2D footage, this plugin is totally useless to you. This plugin is intended to follow a target through the scene of your video and add a new layer or two with the information showing on the footage that they are added above your actual footage.
The 3D camera tracker can be used to perform camera movement tracking automatically of objects, such as a car, in a first or third person perspective. It’s based on the optical flow technique and requires as few as two images to track the motion of an object on which a marker is placed. The marker is initially placed manually in both images, but we’ll see how it can be automatically tracked using the 2D point tracker tool provided by Inferno.
3d Camera Tracker Plugin For After Effects Cs4
WHAT IS CAMERA TRACKER
Camera Tracker for After Effects®* lets you pull 3D motion tracks and matchmoves without having to leave After Effects. 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.
This 3D motion tracking technology was previously only available in NukeX, Foundry’s high-end film compositing tool. You can now do all this within Adobe® After Effects®.
*As of March 31, 2017, we discontinued Camera Tracker for After Effects. After this date we will end, sales, development and support.
Camera tracking directly inside After Effects
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.
Core tracking workflow
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.
Point cloud preview
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.
Stats readouts & refined workflow
Camera Tracker features a comprehensive solve stats and refinement workflow. Standard After Effects parameters are set showing a number of useful statistics, both after the track phase and after the solve phase.
Camera Tracker can estimate the lens distortion of the tracked clip for you, then provides the ability to both flatten and re-distort the plate. It will additionally refine an estimate you dial in, and it supports both spherical and asymmetric distortions.
Focal length & film back estimation
Camera Tracker is able to work from either known focal length and film back shots, or to estimate this data for you using its high tech and production tested solve phase algorithms. Locked and varying focal lengths can be calculated, and a flexible ‘refine’ function allows you to explicitly define a rough estimate should you wish to lock to a particular range.
In addition to supporting standard moving camera shots, Camera Tracker’s flexible track validate and solve stages can additionally be locked down to solve nodal pans (i.e. where camera body and lens is rotated around the nodal point of the combination).
