Add Tracker: IntelliTrack
Adds an IntelliTrack tracker at the current frame.
Point tracking and match move
Tracks one or more image features and can apply the resulting motion to graphics, stabilization or masks.
Tracker is the classic point-tracking node for following high-contrast features through a shot.
Overview
Tracker follows a recognizable feature frame by frame. The tracked motion can then drive a graphic, stabilize the source, or help a mask follow an object.
A good tracking point has stable contrast and texture. Flat surfaces, reflections, motion blur and objects leaving the frame make point tracking less reliable.
Use the simplest tracking model that matches the shot. For broad surface perspective changes, Planar Tracker is often better than forcing several point tracks to solve the motion.
Tracker locks onto a visible feature and records how that feature moves over time.

Adds an IntelliTrack tracker at the current frame.
Adds a standard point tracker at the current frame.
Lists the trackers in this node and lets you select the track you want to edit.
Tracks the selected points backward or forward from the current frame.
Use the one-frame buttons when you need to step through a difficult section manually.
Controls how densely points are drawn along the tracked path in the Viewer.
Controls how the tracker updates its reference pattern as the shot changes.
Sets the center used when displaying or applying the tracked path.
Shows the solved center position of the selected tracker.
Offsets the applied track in X and Y without changing the underlying tracking data.
Chooses how the tracking data is used, such as Match Move, Stabilize or Corner Positioning.
Applies the tracked motion to another element instead of removing that motion from the source.
Uses multiple trackers to drive a four-corner placement.
Allows a corner-positioned result to follow perspective changes in the tracked surface.
Chooses how the pivot is handled when tracking data drives rotation and scale.
Sets the reference frame used when the track is applied for stabilization or match moving.
Shows tracker pattern names in the Viewer.
Temporarily enlarges the tracker pattern view while you drag or refine a tracking region.
Sets the size of that temporary enlarged pattern view.
Scales the search region used to find the tracked feature on neighboring frames.
A larger search area can follow faster motion but costs more processing and may pick up competing detail.
Practical setup
Choose a clear feature.
Set the pattern and search area.
Track through the shot.
Inspect for drift or jumps.
Correct bad frames or choose a better feature.
Use the data for match move, stabilization or mask assistance.
Examples
Track a point and use the match move to keep text attached.
Use tracked motion in Stabilize mode.
