Inputs
The Camera Tracker has two inputs:
Background: The orange image input accepts a 2D image you want tracked.
Occlusion Mask: The white occlusion mask input is used to mask out regions that
do not need to be tracked. Regions where this mask is white will not be tracked.
For example, a person moving in front of and occluding bits of the scene may be
confusing to the tracker, and a quickly-created rough mask around the person can
be used to tell the tracker to ignore the masked-out bits.
Basic Node Setup
The Camera Tracker background input is used to connect the image you want tracked. Polygon
masks can be connected into the occlusion mask input to identify areas the tracker
should ignore.

Track Tab
The Track tab contains the controls you need to set up an initial analysis of the scene.
Auto Track
Automatically detects trackable features and tracks them through the source footage. Tracks
will be automatically terminated when the track error becomes too high, and new tracks are
created as needed. The values of the Detection Threshold and Minimum Feature Separation
sliders can be used to control the number and distribution of auto tracks.
