# Changing the Reference Point

Change the reference point to another feature if the feature you have been tracking moves out of the frame, or alters such that it is no longer trackable. You should do this before the original reference point moves out of the frame. This allows the Stabilizer to calculate the offset between the two reference points and predict the position of the original reference point. If the Path button in the Setup menu is enabled, you will see the extrapolated path of the original reference point.

Change the reference point before analysing the clip.

To change the reference point:

1. Click Setup and then enable Path.
2. Select the tracker for which you want to change the reference point.
3. Display the desired frame in the image window.
4. Select Add from the Edit Mode box.
5. Ctrl+Shift-drag the reference box and position it on the new reference point.
6. Go to the first frame of the sequence and click Analyse.
