• Layout and Padding: When “Projection mode” is set to Cubic, these fields become
available, allowing you to adjust the six faces of the unfolded cube. Most of the time,
there’s no need to change these values. The integer value in the Layout field specifies
the order of the six unfolded cube faces (the default value of 0 specifies the face order
used in the Spherical Video V2 metadata standard: right, left, up, down, front, back).
The value in the Padding field specifies the width (in pixels) of borders around the
edges of each cube face.
For information about working with 360° metadata, see View 360° video metadata using
Compressor.
