83Compressor User Guide
• Bottom First: The field containing the bottom line (odd lines) is sampled at an earlier
instant in time than the field containing the top line (even lines). Bottom-first field
order is commonly used for standard-definition NTSC video.
• Color space: Use this pop-up menu to choose a color space to apply to the source clip
in the job. This property defines how Compressor interprets the color data in the source
clip; it doesn’t convert the clip you output to another color space. To convert from one
color space to another upon output, use the “Color space” pop-up menu in the Video
pane for each specific setting in the batch.
Note: If the source file is tagged with a color space (such as Rec. 709), Compressor
adds an asterisk (*) to the item in the pop-up menu. If the source file is untagged or
tagged with an unrecognized color space, Compressor chooses the most likely color
space and adds a dagger (†) to the item in the pop-up menu.
• 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.
Job annotation
The Job Annotation area of the Job inspector in Compressor contains the Field pop-up
menu, which lets you include annotation metadata in your output file. See Work with
metadata annotations in Compressor.
HDR metadata
If a high-dynamic-range source file has HDR metadata, the values are shown in the HDR
Metadata area of the Job inspector. After you apply a transcode setting to the source file,
Compressor passes this metadata to the export file. When a user plays the exported video
on a TV or display that supports HDR, the device detects the metadata and automatically
adjusts its color levels. You can modify those values in the following fields (if these fields
are not visible, move the pointer to the right of the HDR Metadata heading in the Job
inspector, then click Show):
• Include HDR metadata: To include HDR metadata in your output file, select this
checkbox. (If Compressor detects HDR metadata in the source file, it automatically
checks this box.)
• Primaries: Use this pop-up menu to select a standard preset color space, or choose
Custom to set your own chromaticity coordinate values.
• Red, Green, Blue, White point: Displays chromaticity coordinates (an x value and a
y value) for each of the three primary colors and for the white point of the targeted
display (an HDR-capable device).
• White Point: Use this pop-up menu to select a standard preset white point, or choose
Custom to set your own.
• Luminance: Displays the minimum and maximum luminance of the targeted display in
nits (candelas per square meter).
