Workflows and system setup

In terms of performance, it’s usually best to dedicate a different disk to each asset type, but you can also specify folders
on the same disk. You can specify unique scratch disk locations for each of the following types of files:
Captured Video Video files that you create using File > Capture.
If you transfer video files to a scratch disk folder before creating the project for them, specify the folder containing the
video files for Captured Video.
Captured Audio Audio files that you create using File > Capture, or by recording through the Audio Mixer as when
recording a voiceover.
Video Previews Files created when you use the Sequence > Render Entire Work Area command, export to a movie file,
or export to a device. If the previewed area includes effects, the effects are rendered at full quality in the preview file.
Audio Previews Files created when you use the Sequence > Render Entire Work Area command, use the Clip > Audio
Options > Render And Replace command, export to a movie file, or export to a DV device. If the previewed area
includes effects, they are rendered at full quality in the preview file.
Specify scratch disks
You set up scratch disks in the Scratch Disk pane of the Preferences dialog box. Before changing scratch disk settings,
you can verify the amount of free disk space on the selected volume by looking in the box to the right of the path. If
the path is too long to read, position the pointer over the path name, and the full path appears in a tool tip.
1 Choose Project > Project Settings > Scratch Disks.
2 Identify a location for each type of file named in the dialog box. Premiere Pro creates a subfolder named for each
file type (for instance, Captured Video) and stores the folder’s associated files in it. The menu lists three default
locations:
My Documents (Windows) or Documents (Mac OS) Stores scratch files in the My Documents folder (Windows) or
Documents folder (Mac OS).
Same As Project Stores scratch files in the same folder where the project file is stored.
Custom Allows you to specify a location of your choosing. Choose Custom, then click Browse and browse to any
available folder.
Optimizing scratch disk performance
For optimum performance, follow these guidelines:
• If your computer has only one hard disk, consider leaving all scratch disk options at their default settings.
• Set up scratch disks on one or more separate hard disks. In Premiere Pro, it’s possible to set up each type of scratch
disk to its own disk (for example, one disk for captured video and another for captured audio).
• On Windows, specify only partitions formatted for the NTFS file format as scratch disks. On Mac OS, use partitions
formatted for Mac OS Extended. FAT32 partitions are not recommended for video. They do not support large file
sizes.
• On Mac OS, disable journaling for best performance.
• Specify your fastest hard disks for capturing footage and storing scratch files. You can use a slower disk for audio
preview files and the project file.
• Specify only disks attached to your computer. A hard disk located on a network is usually too slow. Avoid using
removable media because Premiere Pro always requires access to scratch disk files. Scratch disk files are preserved
for each project, even when you close the project. They are reused when you reopen the project associated with
them. If scratch disk files are stored on removable media and the media are removed from the drive, the scratch
disk won’t be available to Premiere Pro.
