Note:
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:
When working with NTSC video assets, use 30-fps drop-frame timecode. This format conforms with the timecode base inherent in NTSC
video footage and displays its duration most accurately.
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 each minute except every tenth minute. Using drop-frame timecode
drops timecode numbers, not the actual frames of video. Use drop-frame timecode for output to NTSC videotape.
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.
Reports time in hours, minutes, seconds, and frames; separating units with colons. Use for 24p footage and to output to
24-fps formats for film and DVD distribution.
Reports time in hours, minutes, seconds, and frames, separating units with colons. Use for output to PAL videotape.
Reports time in feet and frames, assuming the frame rate of 16mm film: 40 frames per foot. Use for output to
16mm film.
Reports time in feet and frames, assuming the frame rate of 35mm film: 16 frames per foot. Use for output to
35mm film.
Reports time solely in a running count of frames. Does not assign measurements of either time or spatial length. Use to output
sequential stills such as those generated for an animation or DPX film editor.
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.
Specifies whether audio time display is measured using audio samples or milliseconds. Display Format applies when
Show Audio Time 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.)
Video Previews settings determine the file format, compressor, and color depth Premiere Pro uses for preview files and
playback of clips and sequences.
Among the various options, you can reduce the frame size of previews. This reduction permits faster and easier playback of formats with large
frame sizes, such as HD and RED.
Select a file format that gives the best quality previews while keeping rendering time and file size within tolerances
acceptable for your system. For certain editing modes, only one file format is available.
Specifies the codec used for creating preview files for the sequence.
(Windows only) The Uncompressed UYVY 422 8-bit codec and the V210 10-bit YUV codec match the specifications for SD-SDI and HD-
SDI video respectively. Select one of them if you intend to monitor or output to one of these formats. To access either of these formats,
first choose the Desktop Editing Mode.
If you use a clip without applying effects or changing frame or time characteristics, Premiere Pro uses the original codec of the clip for
playback. If you make changes that require recalculation of each frame, Premiere Pro applies the codec that you choose here.
