• 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.
• Dithering: When selected, adds a certain type of noise to images to prevent large-scale
distracting patterns such as color banding. If your image has excessive noise after
rendering, deselect this checkbox.

Image Sequence settings in Compressor
The built-in OpenEXR Image Sequence and TIFF Image Sequence settings in Compressor
(in the Motion Graphics category) use the Image Sequence transcoding format. This format
encodes a variety of image sequence file types used in motion graphics, including TIFF,
OpenEXR, JPEG, PNG, animated PNG (APNG), animated GIF, and more.
Note: You can also create custom settings that use the Image Sequence transcoding
format. However, the built-in image sequence settings (in the Settings pane) 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 transcoding format are located
in the General inspector and Video inspector (described below).
Setting summary
Displays the setting name and transcoding format used by Compressor, as well as an
estimated output file size. When you add a setting to a job or change the setting’s
properties, this summary is automatically updated.
General properties
• Name: Displays the name of the setting.
• Description: Displays the description of the setting.
• Extension: Displays the extension of the output file.
Tip: To output a file with a different extension, choose a different file type from the
“Image type” pop-up menu.
• Allow job segmenting: If you’ve set up distributed processing, select this checkbox
to have Compressor process the output file using your shared computer group. See
Transcode batches with multiple computers using Compressor.
