Editing sequences and clips
Last updated 11/6/2011
DV video and audio use standardized settings that are specified automatically when you select either DV editing mode.
When you use a DV editing mode, avoid changing the Timebase, Frame Size, Pixel Aspect Ratio, Fields, and Sample
Rate settings.
Note: (Windows only) To access the Uncompressed UYVY 422 8-Bit codec or the V210 10-bit YUV codec, select Desktop
for the Editing Mode.
Timebase
Specifies the time divisions 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 are often set to the same value. The options listed for
Timebase vary according to the editing mode you select.
Playback Settings
For information about Playback Settings, see “
Preview on a television monitor via camcorder or
Frame Size
Specifies the dimensions, in pixels, for frames when you play back sequences. In most cases, match the
frame size for your project to the frame size of your source files. Don’t change the frame size to compensate for slow
playback. Instead, adjust playback resolution by choosing a different quality setting from the Project panel 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. If you use a pixel aspect ratio that is
different from the pixel aspect ratio of your video, the video often plays back and gets rendered with distortion.
Fields
Specifies the field order, or which field of each frame is drawn first. If you work with progressive-scan video,
select No Fields (Progressive Scan). Many capture cards capture fields regardless of whether the source footage was
shot with progressive scan. (See “
Interlaced video, noninterlaced video, and progressive scanning
Display Format (Video)
Premiere Pro can display any of several formats of timecode. You can display the project
timecode in a film format, for example, if you are editing footage captured from film. You can display timecode in
simple frame numbers if your assets came from an animation program. Changing the Display Format option does not
alter the frame rate of clips or sequences—it changes only how their timecodes are displayed. The time display options
correspond to standards for editing video and motion-picture film. For Frames and Feet + Frames timecodes, you can
change the starting frame number to match the time-counting method of another editing system you use.
The options made visible in the Display Format field depend on the Editing Mode selected. You can choose from the
following Display Format options, depending on which editing mode is selected:
•
30 fps Drop-Frame Timecode
Reports time in hours, minutes, seconds, and frames, separating units with
semicolons. Drop-frame timecode assumes a rate of 30 frames per second (fps), but skips some numbers by design. To
accommodate the NTSC actual frame rate of 29.97 fps drop-frame timecode skips, or drops, two frame numbers (not
the actual frames of video) each minute except every tenth minute. Use for output to NTSC videotape.
30 fps drop-frame timecode as indicated by semicolons
•
30 fps Non Drop-Frame Timecode
Reports time in hours, minutes, seconds, and frames, separating units with
colons. It assumes a rate of 30 fps and does not drop frame numbers. Use for output to computer displays via the web
or CD-ROM.
