Use Pretracking to preview the motion path before processing, and Oversampling to use high-quality subpixel image adjustment.
Before analysing, you can use the Pretracking option in the Setup menu to preview the motion path for a specified number of frames. You can then adjust the tracker position, if necessary, to find the best reference point. The Pretracking option applies only to the selected tracker, regardless of whether you selected Solo, Selected, or Gang in the Tracker Selection box. If you move or resize a tracker with Pretracking enabled, the next frames are analysed.
To pretrack a clip:
The motion path appears.
Use Oversampling to toggle high-quality subpixel image adjustment on and off:
After you stabilize a clip with Oversampling on, rotoscope it in Paint to remove the border that appears at the edges. Avoid using Action (or any other component that uses texture memory) to do this because you will lose the benefits of Oversampling.
