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 a keystone correction option.

Select: | To:
--- | ---
Manual | Apply keystone corrections manually in this menu.
From Analyzer | Use the automatic settings derived from the selected analyzer.
Pass Through | Inherit Stereo Mode settings from the stereo camera. 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 fields (Left Eye/Right Eye/Current Camera)
  Displays the offset distance between the left and right eye compared to the FBX camera. The Current Camera fields display the Interaxial of the selected camera.
FOV Offset fields (Left Eye/Right Eye/Current Camera)
  Displays the offset field of view between the left and right eye compared to the FBX camera. The Current Camera fields display the FOV of the selected camera.
Stereo Clip Type box
  Specify how the footage was shot: Parallel, Off-axis, or Converged.
Camera box
  Select the camera to which the stereo object is linked so that the correct transformations are applied when changing the Interaxial and FOV offset with regards to the FBX camera setting.
Edit Mode settings

Select: | To:
--- | ---
Sync L+R | Link the Left Eye and Right Eye values. 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.
Absolute/Relative | Absolute: Make the values of the Left Eye and Right Eye the same. Relative: Make the value of one eye relative to the change in the value of the other eye.
