• Color space: Use this pop-up menu to convert the source media to a new color space,
including wide color gamut. Choose Automatic to allow Compressor to choose the best
color space based on the selected preset. You can also choose a manual setting to
override the default. For more information about wide color gamut, see Intro to wide
color gamut and HDR in Compressor.
• RAW to log: Use this pop-up menu to select how ProRes RAW conversion is done.
Choose Automatic to allow Compressor to choose the conversion method. You can
also choose a manual setting to override the default. This option is available only if
the source is ProRes RAW.
• Camera LUT: Use this pop-up menu to select the camera lookup table (LUT) applied
to the source. Select a custom LUT to transform your video from one color space to
another. This setting is enabled if the source is ProRes RAW and if “RAW to log” is
set to a value other than None. This setting is also enabled if “Camera log” in video
properties in the Job inspector is set to a value other than None.
• Scale image to preserve aspect ratio: Select this checkbox to scale the output files to
use square pixels and maintain the original aspect ratio (which results in an increase or
decrease in the number of horizontal and vertical pixels).
• Color depth: Use this pop-up menu to set the number of bits used to represent color in
each color channel (red, green, and blue). Choose 8 or 16 (for better quality).
Cropping and padding
Customize the final cropping, sizing, and aspect ratio using the Cropping & Padding
properties in Compressor. Cropping removes video content from an image. Padding
scales the image to a smaller size while retaining the output image’s frame size. For more
information about these properties, see Intro to modifying frame size in Compressor.
• Cropping: This pop-up menu sets the dimension 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 option detects image edges and
automatically enters crop values to match them. This is useful if you want to crop out
the letterbox area (the black bars above and below a widescreen image) of a source
media file.
• Padding: This pop-up menu sets 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.
Quality
The following properties determine how the video will be resized, retimed, and otherwise
adjusted when transcoded in Compressor:
• 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.
