• 360° metadata: Use this pop-up menu to choose the type of 360° metadata, if any,
included in the output file:
• 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.
• Spherical Video V1: The 360° metadata format most commonly used by sharing sites,
including YouTube and Vimeo.
• Spherical Video V2: A less common, but more up-to-date, 360° metadata format
used by YouTube and Vimeo.
For more information, see View 360° video metadata using Compressor.
• Compatible with: This list shows devices that will play the transcoded file (compatible
device types are marked with a green circle that contains a checkmark
).
When
you change the setting’s properties (frame size, frame rate, codec, and so on), the
compatibility list is automatically updated.
Cropping and padding
Customize the final cropping, sizing, and aspect ratio in Compressor using the Cropping &
Padding properties. Cropping removes video content from an image. Padding scales the
image to a smaller size while retaining the output image’s frame size.
• Cropping: Use this pop-up menu to set the dimensions of the output image. The custom
option allows you to enter your own image dimensions in the fields; other options use
predetermined sizes. The Letterbox Area of Source menu item detects image edges and
automatically enters crop values to match them. This is useful if you want to remove
a source file’s letterbox area, by cropping out the black bars above and below the
widescreen image.
• Padding: Use this pop-up menu to set the scaling of the output image while retaining
the output image’s frame size. The custom option allows you to enter your own scaling
dimensions in the fields; other options use predetermined dimensions.
For more information about these properties, see Intro to modifying frame size in
Compressor.
Quality
The following properties in Compressor provide instructions for image analysis, including
frame resizing, clip retiming, and deinterlacing:
• Resize filter: This pop-up menu sets the resizing method. There are several options:
• Nearest Pixel (Fastest): Samples the nearest neighboring pixel when resizing an
image. This option provides the fastest processing time, but it is more likely to
show aliasing artifacts and jagged edges.
• Linear: Adjacent pixel values are averaged using a linear distribution of weights.
Produces fewer aliasing artifacts than Nearest Pixel, with a small increase in
processing time.
• Gaussian: Adjacent pixel values are averaged using a gaussian distribution
of weights. This provides a medium trade-off between processing time and
output quality.
