User Guide
Ignore Audio Filters
Select to play back audio from the Timeline without applied audio filters.
Ignore Video Filters Select to play back video from the Timeline without applied video filters.
Ignore Audio Rubber Bands
Select to play audio from the Timeline excluding changes made
using the rubber-band controls for audio fading and audio panning in the Timeline.
Optimize Stills
Select to use still images efficiently when playing back video from the Timeline.
For example, if a still image has a duration of 2 seconds in a project set to 30 frames per second,
Premiere will create one 2-second frame instead of 60 frames at 1/30 of a second. Deselect this
option if the exported video file exhibits playback problems when displaying the still images.
Field settings
Select an option that matches the playback display. No Fields is the default and is
the equivalent of progressive scan, the correct setting for previewing on a computer display.
Select Upper Field First or Lower Field First when playing back video on a television monitor
using an interlaced standard such as NTSC, PAL, or SECAM; the option you actually choose
depends on the specific video hardware you use. For more information on fields, see
“Comparing interlaced and non-interlaced video” on page 341.
Keyframes can increase the effectiveness of compression (see “Temporal compression” on
page 349). If the codec you specified supports compression keyframes, the following Keyframe
Options are available:
Keyframe Every _ Frames
Select and type an interval of frames after which the codec will create
a keyframe when exporting video.
Frames Only at Markers
Select when you want to play back only the frames at which you have
added a marker in the Timeline. This option does not affect keyframes.
Add Keyframes
Select At Markers to create a keyframe at each marker. Select At Edits to also
create a keyframe between each clip.
