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.
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.
Use preview files when rendering
In the Export Settings dialog box, check Use Previews.
