To fine-tune the track analysis:
1 Use the Quality slider to adjust the number of good trackers kept. The higher the quality setting, more
low quality trackers are selected, such as trackers that drift off their initial reference point. Click Delete
to delete the selected trackers.
Trackers of lower quality may hinder the accuracy of the camera tracking.
NOTE After you have made a change that requires the 3D tracking analysis to be refined or updated, notice
that the LED next to the Refine and Update buttons turns yellow. This signifies that a Refine or Update is
required, but you do not have to perform it until you have completed your tracker selections.
2 Adjust the Short slider to select short duration trackers, that is, trackers that only track a feature for a
few frames. Click Delete to delete the selected trackers, leaving the longer duration trackers intact.
3 You can manually select and delete trackers from the image that you feel are not tracking properly.
Do one of the following:
■ To select an individual tracker, click the tracker, and then click Delete.
■ To select multiple trackers in the same area, Ctrl-drag a selection box over a series of trackers, and
then click Delete.
■ With Delete mode selected in the Tools box, select trackers in the image.
Refining or Updating the Track
Once you are satisfied with your fine tuning changes, you can refine or update your Analyzer.
To refine or update the 3D track:
1 Depending on the changes you have made, you can choose to refine or update the 3D track. Do one
or both of the following:
■ Click Update.
NOTE The update operation deletes all previous 3D points and starts over based on the new information.
Depending on your footage, and how many trackers you added, deleted, or linked, multiple updates may
yield different results.
■ Click Refine.
The track analysis uses the current results as a starting point, and refines from this point.
