Video properties
The properties in this section are set based on the file format assigned to the setting. You can
change the file format in the General pane of the inspector; for more information, see the
"Settings” property in the “General properties” section, above.
•
Frame size: For settings that use the QuickTime Export Component format, this property is set
to Automatic.
•
Pixel aspect ratio: For settings that use the QuickTime Export Component format, this property
is set to Square. You can also modify the aspect ratio of the output file using cropping and
padding properties; for more information, see
on page 67.
•
Frame rate: Use this pop-up menu to set the playback rate (the number of images displayed
per second) for the output file. For more information, see
page 69.
•
Field order: For settings that use the QuickTime Export Component format, the field order is
set automatically.
Cropping and Padding
Customize the final cropping, sizing, and aspect ratio 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. For more information about these properties, see
on page 67.
•
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
For a list of available video effects and instructions on how to add a video effect to a setting, see
on page 74.
QuickTime Movie
Many of the built-in settings in the Settings pane use the QuickTime Movie format. This format
encodes video files for many uses. You can also create custom settings that use the QuickTime
Movie transcoding format.
The properties of built-in and custom settings that use this format are located in the General,
Video, and Audio inspectors. These properties are described below.
Important:
When you add a setting (or a destination that includes settings) to a job, Compressor
analyzes the source media and then automatically assigns the most appropriate setting
properties (based on the setting’s transcoding format and the characteristics of your source
media file). It’s recommended that you use the automatically assigned setting properties.
Setting summary
Displays the setting name and transcoding format, as well as an estimated output file
size. When you add a setting to a job or change the setting’s properties, this summary
automatically updates.
