Clear Main Video Track Playlist
When selected,
all existing video regions in the currently-se-
lected playlist on the main video track will be re-
moved from the track before Pro Tools imports
video into the session. No other playlists, video
tracks, or video regions will be affected. (This
option is only enabled if the main video track is
selected as the Destination option.)
Bypassing the Video Import Options Dialog
You can bypass the Video Import Options dialog
when dragging video files into Pro Tools. The
video files are added exactly where you drop
them in the Timeline following the current
Pro Tools editing mode.
To bypass the Video Import Options dialog when
importing video into Pro Tools:
„
Alt-drag (Windows) or Option-drag (Mac) one
or more video files from a DigiBase browser,
Windows Explorer, or Mac Finder into the Re-
gion List or the Timeline.
Extracting Audio from
QuickTime and Windows
Media Video
(QuickTime and Windows Media Video Only)
You can extract many audio file formats from
QuickTime and Windows Media video files
without importing the video.
The audio is converted to the session’s sample
rate and bit resolution, and a new region ap-
pears in the Region List for each imported file.
The regions are listed in the Region List with the
region name, the number of the originating
track, and the number of the region from the
track.
To import audio from a QuickTime or Windows
Media video file without importing the video, do
the following:
1
Choose
File > Import > Audio
.
2
In the Import Audio dialog, navigate to the
video file from which you want to import audio,
and select it.
3
Under the Region section, click the name of
the audio region you want to extract from the
video file, and click
Convert Region
or
Add Region
.
4
Select other audio files , and click Done to im-
port the audio.
5
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.
See “Video Engine Rate” on page 1042 for
more information.
Pro Tools cannot extract audio from
Windows Media video files that require
Windows Media File Digital Rights
Management (DRM) passwords.
