Specify whether to render audio when rendering video
You can specify whether Premiere Pro renders audio previews by default when you select Sequence > Render Effects
In Work Area, or Sequence > Render Entire Work Area. Rendering audio previews could improve playback
performance, but could take additional time when you select either of these commands.
1
Select Edit > Preferences > General (Windows), or Premiere Pro > Preferences > General (Mac OS).
2
Select or deselect Render Audio When Rendering Video.

Click OK.
Specify the duration for preroll and postroll pauses
You can set the length of preroll and postroll for clip and sequence previews in the General pane of the Preferences
dialog box.
Note: The Preroll and Postroll fields are different from the Preroll setting in the Device Control pane of the Preferences
dialog box. The Preroll setting in the Device Control pane affects the control of external devices such as VTRs and
camcorders.

Specify scratch disks to improve system performance
When you edit a project, Premiere Pro uses disk space to store files required by your project, such as captured video
and audio, conformed audio, and preview files that you create manually or that are created automatically when
exporting to certain formats. Premiere Pro uses conformed audio files and preview files to optimize performance,
allowing real-time editing, 32-bit floating-point quality, and efficient output.
All scratch disk preferences are saved with each project. You may select different scratch disk locations for different
projects. If you reopen an earlier project after editing another project with different scratch disk locations, Premiere
Pro will seek out the files belonging to the earlier project at the scratch disk locations you chose for that project.
If you delete preview files or conformed audio files for a project, Premiere Pro automatically recreates them when you
reopen the project.
By default, scratch disk files are stored where you save the project. The scratch disk space required increases as
sequences become longer or more complex. For best performance, it is recommended that you dedicate a hard disk or
disks, (other than the disk where you keep your project file, your operating system files, or your files for applications)
strictly to your media assets. That way your media disks can access and play media files as fast as possible, without
having to access other files. If your system has multiple disks, you can use the Project > Project Settings > Scratch Disks
command to specify which disks Premiere Pro uses for media files. This is best done when you set up a new project.
