The associated scene point objects are set up in 3D space based on real-world
dimensions.
5 (Optional) Use the Movie Stepper rollout to set the start and stop frames
for each tracker if it’s out-of-view for any of the frames that will be
matched. These specify the frame range during which the tracker is visible
in the scene and will be tracked as part of the matching process. This
mechanism allows you to match a move in which the view passes through
a field of features with only some of them (at least six) visible at any time.
6 (Optional) Set up manual keyframes for each tracker at frames in which
the feature radically changes motion or shape or is briefly occluded and
so might be difficult for the computer to track. If you want, you can do
this after a tracking attempt indicates where tracking errors occurred.
7 Perform the feature track using the Batch Track rollout. This is often an
iterative process: correcting for tracking errors by tuning start and stop
frames or manually repositioning the gizmo and motion search boxes at
error frames. When you reposition a gizmo at some frame, you establish
a new target feature image and subsequent frames up to the next keyframe
will be retracked. You can use the error detecting features in the tracker
to step through possible tracking errors. When complete, this process
