Editing sequences and clips
Last updated 11/6/2011
(Windows only) The Uncompressed UYVY 422 8bit 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, Adobe Premiere Pro uses the
original codec of the clip for playback. If you make changes that require recalculation of each frame, Adobe Premiere Pro
applies the codec that you choose here.
• 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 ” on page 47.
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 to which you can revert in case someone accidentally alters the current sequence settings.
Tracks settings
Controls the number of video tracks and the number and type of audio tracks for new sequences you create.
Master Sets the default channel type for the Master track in new sequences to Mono, Stereo, or 5.1 surround.
Note: If you must change sequence settings that are unavailable, you can create a sequence with the settings you want.
Then move the contents of the current sequence into it.
Create a custom sequence preset
To customize most sequence settings, you must start a new sequence, select an existing preset, and change its settings.
1 Choose File > New > Sequence, or, in the Project panel, click the New Item button and select Sequence.
2 In the Sequence Presets tab of the New Sequence dialog box, select the preset that most closely matches your video
footage or the requirements of your capture card.
3 Modify the settings on the General or Tracks tabs to meet the needs of your project.
4 Click Save Preset.
5 Name the preset, and, if desired, describe it. Then click OK.
