Render a preview file for a section of a sequence

You can render any part of a sequence that falls under a red render bar.

1Set the work area bar over the area you want to preview.

2Choose Sequence, and select one of the following:

Render Effects In Work Area Renders the sections of the video tracks lying within the work area containing a red render bar. Alternatively, press Enter.

Render Entire Work Area Renders the sections of the video tracks lying within the work area containing either a red render bar or a yellow render bar.

Render Audio Renders a preview file for the sections of the audio tracks lying within the work area.

Note: You can set Premiere Pro to render the audio tracks whenever you render the video tracks. For more information, see “Render audio when rendering video” on page 206.

The rendering time depends on your system resources and the complexity of the segment.

To maximize the quality of motion in rendered preview files, check the Maximum Render Quality option in Sequence Settings. For more information, see “General settings (CS5) - Settings (CS5.5 and later)” on page 144.

Render audio when rendering video

By default, Premiere Pro does not render audio tracks when you select either Sequence > Render Effects In Work Area, or Sequence > Render Entire Work Area. However, playback may suffer when the data throughput of your disk drive cannot sustain the flow when mixing multiple channels of audio and audio in a complex sequence. You can change this default so that Premiere Pro automatically renders audio previews whenever it renders video previews.

1Select Edit > Preferences > General (Windows) or Premiere Pro > Preferences > General (Mac OS).

2Select or deselect Render Audio When Rendering Video.

3Click OK.

Work with preview files

When you render previews, Premiere Pro creates files on your hard disk. These preview files contain the results of any effects that Premiere Pro processed during a preview. If you preview the same work area more than once without making any changes, Premiere Pro instantly plays back the preview files instead of processing the sequence again. Premiere Pro stores the preview files in a folder you can specify. Similarly, preview files can save time when you export the final video program by using the processed effects already stored.

Note: Adobe Media Encoder does not automatically use Premiere Pro preview files for encoding. To make use of the Premiere Pro preview files, you must select the Use Previews option in Adobe Media Encoder for each encoding process.

To further save time, Premiere Pro maintains existing preview files whenever possible. Preview files move along with their associated segment of a sequence as you edit your project. When a segment of a sequence is changed, Premiere Pro automatically trims the corresponding preview file, saving the remaining unchanged segment.

When completely done with a project, delete preview files to save disk space.
