# Stereo Object Correction Settings

Use the Correction tab of the Stereo Object menu to indicate how the footage was shot, and make interaxial offset and FOV offset adjustments to the left/right images.

The Correction controls are described as follows.

Keystone Correction box
  Select whether to apply keystone corrections manually in this menu, use the automatic settings derived from the selected analyzer, or inherit the Stereo Mode settings from the stereo camera (Pass Through).

  In most cases, a keystone correction is needed if the stereo types of the camera and the stereo object do not match, but there may be cases when you want to sync the two.

Correction Analyzer box
  Select which analyzer is used to provide automatic keystone corrections.

Interaxial Offset Left Eye field
  Displays the offset distance between the left eye compared to the FBX camera. Editable.

Interaxial Offset Right Eye field
  Displays the offset distance between the right eye compared to the FBX camera. Editable.

Interaxial Offset Current Camera field
  Displays the interaxial offset of the selected camera. Non-editable.

FOV Offset Left field
  Displays the offset field of view between the left eye compared to the FBX camera. Editable.

FOV Offset Right field
  Displays the offset field of view between the right eye compared to the FBX camera. Editable.

FOV Offset Current Camera field
  Displays the offset field of view of the selected camera. Non-editable.

Stereo Clip Type box
  Specify how the footage was shot: Parallel, Off Axis, or Converged.

Parent Camera box
  Select which camera in the scene is associated with the stereo object. This setting is also found in the Axis tab of the Stereo menu.

Camera Number field
  Displays the number of the selected camera. Non-editable.

Edit Mode box
  Select whether to sync the left and right eye correction values.

  When synced, a change to one value affects the other value. The left eye position is a combination of the camera’s left eye position and the left interaxial offset; the same applies for the right eye. The effective FOV for the correction is the sum of the camera’s FOV and the FOV offset.

Sync Type box
  Select whether the relationship between the left and right eye correction values is absolute or relative. Available when Sync L+R is selected in the Edit mode box.
