•
Adaptive details: Select this checkbox to use advanced image analysis to distinguish between
noise and edge areas during output.
•
Anti-aliasing level: Sets the softness level in the output image. Double-click the value and
then manually enter a new value or drag the slider to the right to increase softness. This
property improves the quality of conversions when you’re scaling media up. For example,
when transcoding SD video to HD, anti-aliasing smooths jagged edges that might appear in
the image.
•
Details level: Sets the amount of detail in the output image. Double-click the value and then
manually enter a new value or drag the slider to set the value. This sharpening control lets you
add detail back to an image being enlarged. Unlike other sharpening operations, the “Details
level” property distinguishes between noise and feature details, and generally doesn’t increase
unwanted grain. Increasing this value may introduce jagged edges, however, which can be
eliminated by increasing the “Anti-aliasing level” slider.

Sample rate: Use this pop-up menu to set the number of times per second that music
waveforms (samples) are captured digitally. The higher the sample rate, the higher the audio
quality and the larger the le size.
•
Data rate: Use the slider to set the number of kilobits per second (kbps) required to deliver
your audio le. Using a higher rate will produce a higher-quality audio le.

QuickTime Export Components
You can use the QuickTime Export Components transcoding format to output les for a variety
of additional formats that can play on third-party devices and operating systems, such as mobile
phones. You can transcode les for 3G, AVI, and Apple iPod, or transcode using third-party plug-
ins that you’ve installed on your system.
The properties of custom settings that use this transcoding format are located in the General
inspector and Video inspector. 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 le). 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 le
size. When you add a setting to a job or change the setting’s properties, this summary
automatically updates.
