Previewing a Setting

The Compressor Preview window lets you see the effects of your setting—such as filters and frame resizing—and make adjustments to these attributes while previewing the media file in real time.

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).

    Note: To preview the effect of the filters on your media file, you need to make sure that the checkbox for that particular filter is selected in the Filters list. Otherwise, the Preview window won’t recognize that filter, and it will not be part of the transcoding settings for that job. See Using the Preview Window for more information about previewing your settings and About the Filters Pane for more information on filters.
