Correcting Errors
If the tracker box strays from the reference point that it is supposed to be
tracking, incorrect keyframes result. If such an error occurs, you can stop the
analysis, correct it, and restart it at any frame.
There are a number of different methods you can try to correct tracking errors.
Try the strategies given below, then redo the analysis to generate new
keyframes based on the updated information you provide.
Updating the Reference Point
If the tracker loses the reference point, you can delete the incorrect keyframes,
then, at the last good keyframe, update the reference point to the current
contents of the tracker box.
To update the reference point to the tracker box contents:
1 Select the appropriate tracker by clicking the appropriate Tracker button.
2 Press Backspace.
The last keyframe is deleted and the positioner moves back one frame.
The tracker box is now on the previous keyframe.
3 If you want to remove this keyframe, press Backspace again.
4 Repeat step 2 for all incorrect keyframes.
5 When you reach the last good keyframe, click Snap. This updates the
reference point from the one originally specified in the reference frame
to the image currently inside the tracker box.
6 Click Analyze to continue the tracking process.
Resetting the Tracker
If the tracker loses the reference point early in the analysis, you may want to
reset the entire tracker and find a new reference pointsee
