Action Safe Area
Specifies how much of the frame edge to mark as a safe zone for action so that action isn’t cut off
by televisions that zoom the picture slightly to enlarge it. A rectangle marks the action-safe zone when you click the
Safe Margins button in the Source Monitor or Program Monitor.
Sample Rate
In general, higher rates provide better audio quality when you play back audio in sequences, but they
require more disk space and processing. Resampling , or setting a different rate from the original audio, also requires
additional processing time and affects the quality. Try to record audio at a high-quality sample rate, and capture
audio at the rate at which it was recorded.
Display Format
Specifies whether audio time display is measured using audio samples or milliseconds. Display
Format applies when Audio Units is selected in the Source Monitor or Program Monitor menu. (By default, time is
displayed in frames, but it can be displayed in audio units for sample-level precision when you are editing audio.)
Note:
DV video and audio use standardized settings that are specified automatically when you select DV Playback
editing mode. When you use DV Playback editing mode, avoid changing the Timebase, Frame Size, Pixel Aspect Ratio,
Fields, and Sample Rate settings.

Video Rendering settings
Video Rendering settings affect how Adobe Premiere Pro generates video when you select Sequence > Render Work
Area.
Maximum Bit Depth
Maximizes the color bit depth, up to 32 bits, to include in video played back in sequences. This
setting may not be available if the selected compressor provides only one option for bit depth. You can also specify
an 8-bit (256-color) palette when preparing a video program for 8-bit color playback, such as when using the
Desktop editing mode for the web or for some presentation software.
Previews
These options—File Format, Compressor, and Color Depth— specify how Adobe Premiere Pro plays
previews. Select a combination that gives the best quality previews while keeping rendering time and file size within
tolerances acceptable for your system. For certain editing modes, these settings cannot be changed.
Note:
If you use a clip in your video program without applying effects or changing frame or time characteristics, Adobe
Premiere Pro uses the clip’s original codec for playback. If you make changes that require recalculation of each frame,
Adobe Premiere Pro applies the codec that you choose here.
Optimize Stills
Uses still images efficiently in sequences. For example, if a still image has a duration of 2 seconds in
a project set to 30 fps, Adobe Premiere Pro creates one 2-second frame instead of 60 frames at 1/30 of a second each.
Deselect this option if sequences exhibit playback problems when displaying still images.
Save and name your project settings even if you plan to use them in only one project. Saving settings creates a backup
copy of the settings in case someone accidentally alters the current project settings.
To open a project
Adobe Premiere Pro can open project files created with Adobe Premiere Pro or Adobe Premiere 6.x for either
Windows or Mac OS. You can open only one project at a time. If you want to transfer the contents of one project into
another, import them.
