Working with the Corner Pin Tracker

Manually Correcting Errors
If the Tracker cannot locate the Target region in the Search region during analysis, errors can
occur. You can use one of four methods to fine-tune your results:
Use multiple trackers to turn on a second tracker, select the checkbox next to the
tracker’s tab—see “Search/Target Tab (Motion Tracker)” on page 502
Adjust the parameters in the Advanced tab—see Advanced Tab (Motion Tracker)” on
page 505
If this still doesn’t correct the error, you can manually correct the tracker position by
creating a new keyframe in the Motion Tracker track and creating a new Target and
Search area—see “Search/Target Tab (Motion Tracker)” on page 502.
Alternatively, you can select one or more points and manually move them. Once you
move the points, you can lock them.The Motion Tracker only updates the unlocked
points.
Correcting Individual Points
Use this procedure when you want to change or fix motion tracking points.
To adjust individual points:
1. Select the points that are generating errors. Click to select a single point or Shift-click to
select multiple contiguous points. You can also drag a marquee around multiple
contiguous points. To select multiple points that are not contiguous, Ctrl+select the
appropriate points.
Unlocked and unselected points display as a hollow square. Selected points display as a
solid square. Locked points display as a rounded solid square in a complementary color.
2. Drag a selected point to adjust it. Shift-drag to move a group of selected points.
3. After you select and adjust the points, press L to lock the points.
4. Click the Analyze button. The Motion Tracker tracks the points that are not locked. The
tracker picks up the Target and Search Regions from the locked points.
Working with the Corner Pin Tracker
Map media to a specific area on a moving object in a media file with the Corner Pin Tracker.
The Corner Pin Tracker filter includes cross-references to the Motion Tracker filter
documentation.
