Audio and Video Pull Up and Pull Down
Pro Tools provides up to 4.167% pull up, and
4.0% pull down choices. When working with a
Movie track containing video, a separate Video
Pull-Down menu becomes available in the Ses-
sion Setup window, allowing you to apply stan-
dard or non-standard pull factors to audio and
video separately. This lets Pro Tools synchronize
to most supported SMPTE frame rates and for-
mats.
With Pro Tools HD, 4.167% pull up and
4.0% pull down are not available in
176.4 kHz and 192 kHz sessions.
Time Code Rate
While using Pro Tools, the SYNC peripheral
Time Code Rate automatically follows the ses-
sion Time Code Rate setting. Session Time Code
Rate is set in the Session Setup window.
To set the session Time Code Rate:
Choose a rate from the Time Code Rate pop-up
menu in the Session Setup window.
Choosing a session Time Code Rate
In Standalone mode, the SYNC peripheral Time
Code Rate can be set using the SYNC Setup soft-
ware utility (Windows only), or from the front
panel.
