Note: The Editing Mode setting should represent the specifications of the source media,
not the final output settings. Specify output settings when you export; see “Exporting
video as a file” on page 296.
Timebase
Specifies the time divisions Adobe Premiere Pro uses to calculate the time
position of each edit. In general, choose 24 for editing motion-picture film, 25 for editing
PAL (European standard) and SECAM video, and 29.97 for editing NTSC (North American
standard) video. Do not confuse timebase with the
frame rate
of the video you play back or
export from sequences, although timebase and frame rate often use the same value.
Playback Settings
This button is available when you use a DV preset, choose the DV
Playback editing mode, or install a plug-in that provides additional playback functions.
When you use the DV Playback editing mode, use this option to indicate where you want
your previews to play back: on your DV camcorder (or other connected device) or on your
desktop. For information on the playback settings available for third-party plug-ins, see
the documentation provided by the manufacturer of the plug-in.
Frame Size
Specifies the dimensions, in pixels, for frames when you play back
sequences.
In most cases, the frame size for your project should match the frame size of your source
media. Don’t change the frame size in order to compensate for slow playback—instead,
adjust playback resolution by choosing a different Quality setting from the Project
window menu, or adjust the frame size of final output by changing Export settings.
Pixel Aspect Ratio
Sets the aspect ratio for individual pixels. Choose Square Pixels for
analog video, scanned images, and computer-generated graphics, or choose the format
used by your source media. If you use a pixel aspect ratio that is different from your video,
the video may play back and render with distortion. For more information, see “About
aspect ratios” on page 98.

Fields
Specifies the field dominance, or which field of each frame’s interlaced fields is
drawn first. If you work with progressive-scan video, select No Fields (Progressive Scan).
Note that many capture cards capture fields regardless of whether you shot progressive
scan footage.
Display Format (video)
Specifies the way time appears throughout the project. The time
display options correspond to standards for editing video and motion-picture film. For
broadcast NTSC video, choose 30 fps Drop-Frame Timecode if that is the time display
used
by the original video. For video to be played back from the Web or CD-ROM, choose 30
fps
Non Drop-Frame Timecode. For PAL and SECAM video, choose 25 fps Timecode. For
motion-picture film, choose Feet + Frames 16mm or Feet + Frames 35mm. To count
individual frames and audio samples instead of timecode, choose Frames/Samples.
Title Safe Area
Sets how much of the frame edge to mark as a safe zone for titles, so that
titles aren’t cut off by televisions that zoom the picture slightly to enlarge it. A rectangle
with cross-hairs marks the title-safe zone when you click the Safe Zones button in the
Monitor window. Titles are usually assumed to require a wider safe zone than action.
Action Safe Area
Sets 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 Zones button in the Monitor
window.
Automatically Scale Imported Media to Project Size
Adjusts imported video and still
images so that they fit within the frame, if they are larger or smaller than the frame.
