Transcoding a Portion of the Clip with the Preview Window

Although Geometry (cropping and scaling) and Filters adjustments are displayed instantly in the Preview window, Encoding pane and Frame Controls pane settings are not. To preview Encoder pane and Frame Controls pane settings, do a test transcode of a small section of your source media file.

You can use the Preview window to set In and Out points to transcode only a portion of your media file rather than transcoding the whole thing.

To designate a portion of your media file for transcoding
  1. Open the Preview window.

  2. Choose a clip from the Batch Item pop-up menu or click the Batch Item selection buttons until the clip appears in the pop-up menu.

  3. Do one of the following:

    • Drag the In point to the appropriate location.

    • Drag the playhead to where you want transcoding to begin and click the Set In Point button.

      Figure. Preview window showing In and Out points.
  4. Do one of the following:

    • Drag the Out point to the appropriate location.

    • Drag the playhead to where you want transcoding to end and click the Set Out Point button.

The only segment of the media file that will be transcoded is between the two points that you set. The rest of the clip will not be transcoded.

Important: When you use the markers to specify a segment of the source media file to transcode, they apply to all targets assigned to the file’s job. You can add a source media file multiple times to a batch, creating multiple jobs, and set the In and Out points differently in each job.
