New Track Defaults
There are three methods in which the Camera Tracker node can analyze the scene, and each
has its own strengths when dealing with certain types of camera movement.
Tracker: Internally, all the Trackers use the Optical Flow Tracker to follow features over
time and then further refine the tracks with the trusted Fusion Tracker or Planar Tracker.
The Planar Tracker method allows the pattern to warp over time by various types of
transforms to find the best fit. These transforms are:
Translation
Translation and Rotation Translation, Rotation, and Scale Affine
Perspective
It is recommended to use the default TRS setting when using the Planar Tracker. The
Affine and Perspective settings need large patterns in order to track accurately.
Close Tracks When Track Error Exceeds: Tracks will be automatically terminated when
the tracking error gets too high. When tracking a feature, a snapshot of the pixels
around a feature are taken at the reference time of the track. This is called a pattern,
and that same pattern of pixels is searched for at future times. The difference between
the current time pattern and the reference time pattern is called the track error. Setting
this option higher produces longer but increasingly less accurate tracks.
Solve Weight: By default, each track is weighted evenly in the solve process.
Increasing a track’s weight means it has a stronger effect on the solved camera path.
This is an advanced option that should be rarely changed.
Auto Track Defaults
Set a custom prefix name and/or color for the automatically generated tracks. This custom color
will be visible when Track Colors in the Options tab is set to User Assigned.
Camera Tab
CameraTab
The controls of the Camera tab let you specify the physical aspects of the live-action camera,
which will be used as a starting point when searching for solve parameters that match the
real-world camera. The more accurate the information provided in this section, the more
accurate the camera solve.
The Camera tab includes controls relating to the lens and gate aspects of the camera being
solved for.
