• Cubic: A less common form of spatial mapping, this option represents the
spherical data as an unfolded cube with six faces.
• Pixel bounds: When “Projection mode” is set to Equirectangular, this property
becomes available, allowing you to modify the boundaries of the equirectangular
frame. Most of the time, there’s no need to change these values. However, if you
need to alter the dimensions of 360° video from its 2:1 aspect ratio to a more
conventional aspect ratio (16:9, for example), you can do so using these controls.
Enter values in the Left and Top fields to crop a specific number of pixels from the
left edge and top edge of the image. Enter new values in the Width and Height fields
to change the dimensions of the equirectangular frame.
• 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.
Include 360° metadata in the output file
After you apply a transcode setting to the 360° video source file, make sure the setting
uses the correct metadata format for the output destination you’ve chosen (YouTube,
Vimeo, or another publishing platform). In most cases, Compressor automatically chooses
the correct metadata format for the job, based on the values entered in the Job inspector
and the transcode setting you applied. However, you can modify that choice, if necessary.
1. In the Compressor batch area, select an applied setting.
2. In the Video inspector, click the “360° metadata” pop-up menu (in the Video Properties
area) and choose an option:
• Automatic: Compressor chooses the metadata format based on the properties in the
Job inspector and the transcode setting you applied. The format chosen is listed to
the right of the pop-up menu.
• None: No 360° metadata is attached to your output file.
