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 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 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.
24-fps Timecode 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.
25-fps Timecode Reports time in hours, minutes, seconds, and frames, separating units with colons. Use for output to PAL videotape.
Feet + Frames 16mm Reports time in feet and frames, assuming the frame rate of 16mm film: 40 frames per foot. Use for output to
16mm film.
Feet + Frames 35mm Reports time in feet and frames, assuming the frame rate of 35mm film: 16 frames per foot. Use for output to
35mm film.
Frames 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.
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.
Sample Rate (Audio) 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 (Audio) 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 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.
Preview File Format 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.
Codec 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.
Note: 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.
Width Specifies the frame width of video previews, constrained by the pixel aspect ratio of the original media.
Height Specifies the frame height of video previews, constrained by the pixel aspect ratio of the original media.
Reset Clears existing previews and specifies full size for all following previews.
Maximum Bit Depth Maximizes the color bit depth, up to 32 bpc, to include in video played back in sequences. This setting is often not
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 sequence for 8-bpc color playback, such as when using the Desktop editing mode for the web or for some presentation
software. If your project contains high-bit-depth assets generated by programs such as Adobe Photoshop, or by high-definition
camcorders, select Maximum Bit Depth. Premiere Pro then uses of all the color information in those assets when processing effects or
generating preview files.
Maximum Render Quality Maintains sharp detail when scaling from large formats to smaller formats, or from high-definition to standard-
definition formats. Maximum Render Quality maximizes the quality of motion in rendered clips and sequences. Selecting this option often
renders moving assets more sharply.
At maximum quality, rendering takes more time, and uses more RAM than at the default normal quality. Select this option only on systems
with sufficient RAM. The Maximum Render Quality option is not recommended for systems with the minimum required RAM.
Maximum Render Quality often makes highly compressed image formats, or those containing compression artifacts, look worse because of
sharpening.
Note: For best results with Maximum Render Quality, select Memory from the Optimize Rendering For menu in preferences. For more
information, see Optimize rendering for available memory.
Save Preset Opens the Save Settings dialog box, where you can name, describe, and save your sequence settings.
Save and name your sequence settings even if you plan to use them in only one project. Saving settings creates a backup copy of the settings
