5 Drag the filters up or down within the Filters 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 these filters are processed one by one during transcoding—starting with the
first item in the list—it is important that your filters be organized in the order you want
them. 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.
If you move a filter, be sure to select the checkbox so that Compressor knows to apply
the filter to that setting. As an additional reminder, once you select the moved filter and
then try to select another setting, the Save dialog appears, requiring you to save or revert
the changes to that setting. By default, all selected filters are displayed first in the list.
Note: You can see setting details in the Summary pane of the Inspector window.
See About the Filters Pane for more details.
