Configuring Pro Tools Session
Settings for a New Session
The following describes the recommended ses-
sion settings for creating a new Pro Tools session
when working in an ISIS system.
To create a new Pro Tools session for Avid Unity
ISIS:
1 In Pro Tools, choose File > New Session.
2 In the New Session dialog, select an Audio File
Type for the session that is compatible across all
workstations.
3 Select a Sample Rate for the session that is
compatible across all workstations.
4 Select a Bit Depth for the session that is com-
patible across all workstations.
5 Name the session and save it to an Avid Unity
ISIS workspace.
Audio File Type
Pro Tools supports AIFF and BWF (.WAV) audio
files natively.
For the best media compatibility between
Pro Tools workstations and Avid workstations,
you should choose to work with Broadcast WAV
media files. Make sure the Audio File Type pop-
up menu in the New Session dialog box is set to
WAV when you are creating a new session.
Sample Rate
Pro Tools HD supports sample rates up to
192 kHz, but other Pro Tools and Avid worksta-
tions only support lower sample rates. There-
fore, when working on an Avid ISIS network, it
is vital to use sample rates for shared media that
are supported on all workstations.
It is preferable for all participants in the system
to agree on a standard, universal sample rate for
the sake of compatibility and to avoid media
conversion. Many facilities choose 48 kHz,
which is the industry standard for post produc-
tion and broadcast applications.
You can use the other Playback Engine set-
tings if your session’s audio media files are
on local storage.
New Session dialog
All Sound Designer II files must be con-
verted to a Windows-compatible format for
use in an ISIS system.
The WAV file format is required when
working with audio files containing field re-
corder metadata.
