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.
Copying Shift Channels
Using the Channel Editor, you can copy a tracker's Shift channel values and paste them into any other
channel in any module. For example, you can copy jitter values to the X and Y position channels of an axis
to add realism to a static scene, or to a channel to add noise.
To copy and paste a shift channel:
1 In the Channel Editor, open the folder of the tracker whose shift values you want to copy.
2 Select the X or Y Shift channel, or the entire Shift folder to select both X and Y Shift channels.
3 Click Copy.
4 If necessary, load the clip to which you want to apply the Shift values into the appropriate tool.
5 Open the folder of the channel to receive the copied shift values and select the appropriate channel(s).
6 Click Paste.
Importing and Exporting Data
Import and export tracking and shift data values to an ASCII file using the Import and Export buttons located
in the Track and Shift areas of the Stabilizer menu.
