Apple Compressor 3 - Manual (Page 102)

Note: You cannot preview a setting on its own—it must be assigned to a job with a
source media file first. In addition, Encoder and Frame Controls pane settings cannot be
previewed. If you want to see the effects of settings you make in these two panes, you
can use the Preview window to select a small portion of the source media file to transcode
and then view the output file to see the results. See
Submitting a Batch for more
information.
To view your setting in the Preview window
1 Apply the setting to a job in a batch.
See Assigning Settings to Source Media Files for more information.
2 Select the target with the setting that you want to preview in the Batch window.
3 Do one of the following:
• Click the setting in the Batch window.
• Click the Preview button.
The opening frame of the selected source media file appears in the Preview window, and
the title of the selected setting appears in the Batch Item pop-up menu. The left half of
the screen displays the source media file in its original form (Source view) and the right
half displays what the output image will look like with selected filters and other setting
attributes applied to it (Output view).
