Edges
The Edges menu determines whether the edges of an image that leave the visible frame are
cropped, duplicated, or wrapped when the stabilization is applied. Wrapping edges is often
desirable for some methods of match moving, although rarely when stabilizing the image for
any other purpose. For more information on the controls, see Chapter 107, “Tracker Nodes” in
the DaVinci Resolve manual or Chapter 56 in the Fusion Studio manual.
Position/Rotation/Scaling
Use the Position, Rotation, and Scaling checkboxes to select what aspects of the
motion are corrected.
Match Move Settings
Options for the Match Move settings include Pivot and Reference.
Pivot Type
The Pivot Type for the stabilization is used to calculate the axis of rotation and scaling
calculations. This is usually the average of the combined pattern centers but may be
changed to the position of a single tracker or a manually selected position.
Reference
The Reference controls establish whether the image is stabilized to the first frame in
the sequence, the last frame, or to a manually selected frame. Any deviation from this
reference by the tracked patterns is transformed back to this ideal frame.
As a general rule, when tracking to remove all motion from a clip, set the Merge mode
to BG Only, the Pivot Type to Tracker Average or Selected Tracker, and the Reference
control to Start, End, or Select Time.
Smoothing Motion
When confronted with an image sequence with erratic or jerky camera motion, instead of trying
to remove all movement from the shot, you often need to preserve the original camera
movement while losing the erratic motion.
The Start & End reference option is designed for this technique. Instead of stabilizing to a
reference frame, the tracked path is simplified. The position of each pattern is evaluated from
the start of the path and the end of the path along with intervening points. The result is smooth
motion that replaces the existing unsteady move.
The Reference Intermediate Points slider is displayed when
Start & End is selected to enable the smoothing of motion.
To preserve some of the curvature of the original camera motion, you can increase the value of
the Reference Intermediate Points slider that appears when the Start & End reference mode
is selected.
