5 If you want to apply additional filters, repeat step 4.
6 Drag the filters up or down within the list to set the order in which you want them applied to the
source media file during transcoding.
Drag filters up or down
to set the order in which
you want them to be
applied to the source
media file.
Because filters are processed one by one during transcoding—starting with the first item in the
list—it’s important that your filters be organized in the order you want them. For example, it’s
sensible to place a text overlay filter last, so that the text color you selected isn’t modified by
other applied filters. If you see unexpected results in the Preview window, try changing the order
of the filters in the list.
Note: If you reorder filters applied to a custom setting in the Settings tab, and then try to select
a different setting in the Settings tab, a Save dialog appears, requiring you to save or revert the
changes you made to the custom setting.
Video filters
Compressor includes the following video filters, located in the Video tab of the Filters pane.
BlackWhite 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 let you separately set values
between 0 and 100 for black and white.
The BlackWhite Restore filter contains the following controls:
•
Black: Sets values between 0 and 100 for black.
•
White: Sets values between 0 and 100 for white.
