Sample Rate Conversion Options
These settings let you convert the sample rate of the ses-
sion’s audio files. For example, you can convert from
48 kHz to 44.1 kHz, or from 44.1 kHz to 48 kHz.
Pro Tools|HD systems support sample rates higher than
48 kHz (88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz).
These settings also enable you to convert to compensate
for the 0.1% speed change (pull-up or pull-down) be-
tween 24 fps film and 29.97 fps NTSC video, or the 4%
speed change (pull-up or pull-down) between 24 fps
film and 25 fps PAL video.
Source Sample Rate
This setting enables you to specify the sample rate of the
audio material you are working with in Pro Tools, inde-
pendent of the project sample rate settings.
For example, you may receive a project originated on
Media Composer at 44.1 kHz. If you want to work at
48 kHz in Pro Tools, you should set the Source Audio
Sample Rate setting to 44,100 and the Destination Au-
dio Sample Rate to 48,000.
These settings can also be used to correct for pull-up or
pull-down problems. For example, you may receive an
AAF or OMF transfer from a Film Composer that con-
tains audio media at “film speed” when played back at
48 kHz. You may want to convert all the audio files and
edits to play back at NTSC video speed and 48 kHz.
In this case, set the Source Audio Sample Rate setting to
47,952 and the Destination Audio Sample Rate to
48,000. These settings tell DigiTranslator that you want
to fit 47,952 of the original “film speed” samples into
48,000 of the new “video speed” samples. With these
settings, you sample-rate-convert the material to NTSC
video speed.
You can set the Source Audio Sample Rate either by se-
lecting one of the predefined sample rates from the pop-
up menu, or by typing a value into the text box.
Destination Sample Rate
This setting determines the target session’s audio sam-
ple rate setting, as shown in the Session Setup window,
and the sample rate of all audio files in the target ses-
sion. Available settings include Pro Tools standard sam-
ple rates of 44.1 kHz or 48 kHz. Pro Tools|HD systems
support sample rates higher than 48 kHz (88.2 kHz,
96 kHz, 176.4 kHz, and 192 kHz).
