Apple Compressor 3 - Manual (Page 256)

Note: Once you make any adjustment to a filter, its checkbox is automatically selected.
If you decide that you no longer want to use that filter, be sure to deselect that particular
filter’s checkbox before transcoding.
• Filters list: Select the checkbox next to the filters you want to add to your presets. Filter
settings you select appear in the Summary table in the Summary pane. You can reorder
filters by dragging them up or down in the Filters list. Because these filters are processed
one by one during transcoding—starting with the first entry in the list—it is important
that your filters are organized correctly. For example, it is sensible to place your text
overlay filter last, so that the text color you selected doesn’t get modified by some
other filter.
• Filter controls: The controls available depend on the filter selected in the Filters list. The
slider allows you to make large numerical changes to your setting, while the arrow
control lets you make single incremental number changes. The setting number appears
in the field located between the slider and arrow control.
Video Filters Tab
Compressor includes the following video filters.
Black/White Restore
Restores nearly black colors to pure black and nearly white colors to pure white without
affecting colors in the rest of the image. Use this filter to better compress the solid black
and white areas (the luminance) in the image, such as backgrounds. The two sliders allow
you to separately set values between 0 and 100 for black and white. See
Color Spaces for
information on how color spaces relate to this filter.
• Black: Sets values between 0 and 100 for black.
• White: Sets values between 0 and 100 for white.
