User Guide
•
For Quality, enter a value to affect the picture quality of and disk space used by exported
video. Increasing quality makes the picture look better, but requires more disk space and may
not play smoothly on slower computers.
•
Select Limit Data Rate to _ K/Sec (if available for the selected compressor) to place an upper
limit on the amount of video data produced by the exported video when it is played back.
See “Setting the data rate” on page 300.
Note: In some codecs, quality and data rate are interrelated, so that adjusting one option automat-
ically alters the other.
5 Choose Audio Settings from the menu at the top of the Export Movie Settings dialog box,
and specify the following options:
•
For rate, choose a higher rate for better audio quality in an exported file, or choose a lower
rate to reduce processing time and disk-space requirements. Compact-disc quality is 44 kHz.
Resampling, or setting a different rate than the original audio, also requires additional
processing time; avoid resampling by capturing audio at the final rate.
•
For Format, choose a higher bit depth and stereo for better quality, or choose a lower bit
depth to reduce processing time and disk-space requirements. Compact-disc quality is 16-bit
stereo. Stereo provides 2 channels of audio; Mono provides one channel.
•
For Type, specify the codec for Premiere to apply when playing audio back from the Timeline.
The codecs available depend on the File Type you specified in the General panel in the Export
Settings dialog box. For more information about each codec, see “Finding an appropriate
codec” on page 352.
•
For Interleave, specify how often audio information is inserted among the video frames in
the exported file. A value of 1 frame means that when a frame is played back, the audio for the
duration of that frame is loaded into RAM so that it can play until the next frame appears. If
the audio breaks up when playing, the interleave value may be causing the computer to process
audio more frequently than it can handle. Increasing the value lets Premiere store longer audio
segments that need to be processed less often, but higher interleave values require more RAM.
