pears in the Region List for each imported file.
The regions are listed in the Region List with the

track.

In the Import Audio dialog, navigate to the
QuickTime movie from which you want to im-
port audio, and select it.
3

QuickTime movie, and click Convert Region or
Add Region.

In the Audio Import Options dialog, choose
whether to import the audio into a new track
(and the Region List) or the Region List only.
Sample Rate Conversion Quality
If you import QuickTime audio that was not
originally recorded at the session’s sample rate,
the sample rate is converted to match the audio
to your session. Pro Tools allows you to choose
the quality of the sample rate conversion by
means of the Conversion Quality setting in the
Editing Preferences page.
There are five possible settings, ranging from
Low (lowest quality) to Tweak Head (highest
quality). The higher the quality of sample rate
conversion, the longer it takes to convert the
bounced file.
To set the sample rate conversion quality:
1
Choose Setup > Preferences and click the
Processing tab.
2
Click the Conversion Quality pop-up menu
and select a conversion setting.
