• 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.
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: For settings that use the QuickTime Export Component format, the Padding
property is not available.
Video effects

effect to a setting, see Add and remove effects in Compressor.
QuickTime Movie settings in Compressor
In Compressor, many of the built-in settings in the Settings pane, including the YouTube
& Facebook, ProRes, and Proxy settings, use the QuickTime Movie format. This format
encodes video files for many uses, including a proxy workflow in Final Cut Pro. See
Create optimized and proxy files in Final Cut Pro.
Settings based on the QuickTime Movie format offer a variety of encoders, including
H.264 and HEVC (High-Efficiency Video Coding, also known as H.265). When you add a
QuickTime Movie-based setting to a job, Compressor chooses the appropriate codec. You
can change the codec in the Video inspector. (To transcode using HEVC, your computer
must be running macOS 10.13 or later; HEVC playback requires a recent-generation Apple
device running macOS 10.13 or later, iOS 11 or later, iPadOS 13 or later, or tvOS 11 or later.)
Note: You can also create custom settings that use the QuickTime Movie transcoding
format, including settings that use the HEVC encoder. However, the built-in settings
analyze your source media and assign optimal properties to ensure the best possible
transcoding results.
The properties of built-in and custom settings that use this format are located in the
General, Video, and Audio inspectors (described below).
