Camera Orient
Frame Number [-2147483648..2147483647]
Enter the animation frame here at which the axes defined at the right should rotate parallel to the corresponding world coordinate axis.
Use this setting to define the camera axis that should reflect that of the world coordinate system at the time defined at the left. Select All if all 3 camera axes should be positioned parallel to those of the world coordinate system.
Enable this option to reverse the axis, i.e., to flip the 3D solve.
