Pretracking a Clip

Before analyzing, 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 analyzed.

To pretrack a clip:

1. Position and select a tracker.
2. In the Setup menu, make sure that Path is enabled. If it is disabled, Pretracking is not available.
3. Enter the number of frames to pretrack.
   Note: If you enter a number larger than the length of the clip, only existing frames are pre-tracked.
4. Enable Pretracking.

   The motion path appears.

   Note: Frames, not fields, are pretracked. If you are in Fields mode, frames will be pretracked.
