## Main Stabilizer Menu

Tracker buttons
  Select the Tracker to work with.

Add Tracker button
  Click to add a new tracker.

Active button
  Enable to activate the selected tracker.

Tracker colour pot
  Displays the colour of the selected tracker. Editable.

  When you add a new tracker, the system automatically assigns it a unique colour so that you can easily distinguish between multiple trackers. You can change the colour of an individual tracker or of all the trackers at once.

Tolerance field
  Displays a value the Stabilizer uses to match reference points from frame to frame and to set keyframes. Editable.

Tracker Selection box
  Select which trackers are affected when you change a parameter.

Analyze button
  Click to generate stabilization or tracking data.

Step button
  Click to analyze a single frame and advance to the next frame.

Direction box
  Select to analyze forward or backward.

Snap button
  Click to redefine the reference at the selected frame.

Lock Key button
  Click to lock the selected keyframe as a point on the tracking path. Click again to unlock.

Delete Key button
  Click to delete the selected point on the tracking path.

Source option box
  Select whether to track in Progressive (frame mode) or Interlaced (field mode).

  By default, the Stabilizer works in Progressive (frame mode). Select Interlaced from the Source Option box mode when working with interlaced images, or with images that display a lot of field jitter. In Interlaced (field) mode, the Stabilizer sets two keyframes for every frame: one for the even field and one for the odd field, and an asterisk appears in the image viewer's current frame display to indicate the second field for each frame.

Fixed X button
  Enable to remove vertical jitter.

Fixed Y button
  Enable to remove horizontal jitter.

Reference X field
  Displays the position of the reference box along the X axis. Editable.

Reference Y field
  Displays the position of the reference box along the Y axis. Editable.

Reference Width field
  Displays the width of the reference box. Editable.

Reference Height field
  Displays the height of the reference box. Editable.

Fixed Reference button
  Enable to track the movement of the reference point specified in the reference frame. Disable to update the reference point at each frame during tracking.

  Normally, you use the Stabilizer with the Fixed Reference button enabled. Throughout the analysis, the tracker box follows the movement of the reference point that you specified in the reference frame.

  You may want to track a pattern that changes considerably from the first frame to the last frame in the clip. For example, the pattern may be rotating or may change size or shape. In this case, disable the Fixed Reference button. The reference point is then updated in each frame. In each frame of the analysis, the Stabilizer looks for the reference point from the previous frame.

  NoteUnless you are in Gang mode, you must set the Fixed Reference button for each active tracker individually.

Tracker X field
  Displays the position of the tracker box along the X axis. Editable.

  Use these options in the Stabilizer menu to determine whether to scale or shift a stabilized image, to track in frame or field mode, and to fix the reference box.

  When a clip is stabilized, the image is shifted. You can choose any of the following from the Scale and Shift Option box to fill or remove the area where the image has been shifted.

  Select: | To:
  --- | ---
  Roll | Wrap the image around to fill the area.
  Fill | Rescale both dimensions of the image independently to make it fit into the frame. Note that this can change the aspect ratio.
  Crop Edges | Rescale the shortest edge of the image to fit into the frame and crop the longest edge. There will not be a black border.
  Letterbox | Rescale the longest edge of the image to fit into the frame and fill the rest of the image with a black border.
  Shift | Use a colour to fill the area. Use the adjacent colour pot to pick the colour. You will lose texture and will fill the rest of the image with the color you picked.

Tracker Y field
  Displays the position of the tracker box along the Y axis. Editable.

Tracker Width field
  Displays the width of the tracker box. Editable.

Tracker Height field
  Displays the height of the tracker box. Editable.

Import Track button
  Open the Import Stabilizer menu, where you to import a text file of saved tracking data.

Export Track button
  Click to open the Export Stabilizer menu, where you to export a text file of saved tracking data.

Shift X field
  Displays the difference between the position of the reference box (0,0) and the position of the tracker box in the current frame along the X axis. Editable.

Shift Y field
  Displays the difference between the position of the reference box (0,0) and the position of the tracker box in the current frame along the Y axis. Editable.

Import Shift button
  Click to open the Import Stabilizer menu to allow you to import a text file of saved shift data.

Shift Copy button
  Click to copy the selected Shift channel (including the aspect ratio of the clip).

Export Shift button
  Click to open the Export Stabilizer menu to allow you to export a text file of saved shift data.

Offset X field
  Displays the offset X axis value. Editable.

Offset Y field
  Displays the offset Y axis value. Editable.

## Setup Menu

Pretracking button
  Enable to preview the motion path for a specified number of frames. Active when Path is enabled.

  Before analysing, you can use the Pretracking option 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.

Pretracking field
  Displays the number of frames to pretrack. Editable.

Oversampling button
  Enable to stabilize using a high-quality subpixel shift algorithm. Disable to stabilize using texture memory.

  Use Oversampling to toggle high-quality subpixel image adjustment on and off:

  - When Oversampling is off, texture memory is used.
  - When Oversampling is on, a high-quality subpixel shift algorithm is used. The resulting image is sharp.

  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.

  NoteYou cannot use the Oversampling and Crop Edges options together. If you select Crop Edges, texture memory is used even if Oversampling is on.

Auto Pan button
  Enable to allow the part of the image that is selected to stay in the image window when zoomed in.

Opacity field
  Displays the opacity of the reference image. Editable.

  The reference image (the image where you placed the reference box) appears in transparency when you select a keyframe. Adjust the opacity of the image to make it more or less transparent. When the opacity is set to 0, the reference image does not appear. When the opacity is set to 100, the reference image is completely opaque.

Zoom field
  Displays the magnification factor of the reference box when selected. Editable.

  By default, the reference box turns into a magnifying glass when you select it. Increase or reduce the magnification factor in the Zoom box.

  Zoom: | Result:
  --- | ---
  0 | No zooming. The crosshair appears in the tracker box after you analyse the clip.
  1 | No zooming and no crosshair.
  2, 3, 4, 5 | A magnification factor of 2, 3, 4, and 5, and a crosshair in the tracker box.

Path button
  Enable to display the tracking path.

  The tracking path is the path that the reference point makes as it changes position from frame to frame. By default, the tracking path appears in the image window. You can turn it off by disabling the Path button.

Colour Corrector Input button
  Enable to display any Colour Corrector settings on the clip.

Linetest button
  Enable to display the context view at a lower resolution.

Icons button
  Enable to display the tracker and reference boxes.

  The tracker and reference boxes appear in the image window when a tracker is active. You can hide them by disabling the Icons button. This is useful when working with many trackers.
