shot with progressive scan. (See
Premiere Pro can display any of several formats of timecode. You can display the project
Display Format (Video)
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
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.
•
30-fps Non Drop-Frame Timecode
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
25-fps Timecode
to PAL videotape.
•
Reports time in feet and frames, assuming the frame rate of 16mm film: 40 frames per foot.
Feet + Frames 16mm
Use for output to 16mm film.
•
Reports time in feet and frames, assuming the frame rate of 35mm film: 16 frames per foot.
Feet + Frames 35mm
Use for output to 35mm film.
•
Reports time solely in a running count of frames. Does not assign measurements of either time or spatial
Frames
length. Use to output sequential stills such as those generated for an animation or DPX film editor.
Note: 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.
In general, higher rates provide better audio quality when you play back audio in sequences, but
Sample Rate (Audio)
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 (Audio)
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.)
