Configuring Pull Up and Pull Down
To pull up or pull down audio or video:
1 (Pro Tools 6.3 and below) If you want to use
extended pull up or pull down choose Setups >
Preferences, click the Operation tab, and dese-
lect the “Limit Pull Ups to NTSC/PAL Film Stan-
dards” option.
2 Choose a Pull Up/Down Rate.
Pull Up and Pull Down controls are located in
the Time Code Settings section of the Session
Setup window.
Audio Rate Pull Up/Down Controls audio sam-
ple rate. See “Audio Sample Rate Pull Up and
Down” on page 560.
Video Rate Pull Up/Down Controls video rate.
See “Video Rate Pull Up and Down” on
page 561.
The choices available in these menus are deter-
mined by the session frame rate. Combinations
can be applied by choosing from both menus.
The choices available in these menus are also de-
termined by the Preferences and Auto Match
Pull Factors settings in the Timecode Rate menu.
(In Pro Tools 6.4, this menu is labeled Timecode
Rate. In Pro Tools 6.2 and below, this menu is la-
beled Frame Rate.) See “Extended Pull Up and
Pull Down” on page 559 and “Auto Match Pull
Factors” on page 559.
Extended Pull Up and Pull Down
Preference and Session Setup Controls The Au-
dio Rate Pull Up and Down menu offers all pos-
sible combinations of pull ups and pull downs
for the audio sample rate, regardless of the ses-
sion frame rate.
In addition, if there is a QuickTime video clip in
the timeline, the video rate can be pulled up or
down by 0.1%, regardless of the session frame
rate. Though not an approved workflow, earlier
versions of Pro Tools also enabled pull down of
QuickTime video clips when audio was pulled
down, so this option is included in Pro Tools
5.3.1 and higher to maintain compatibility with
earlier sessions.
Auto Match Pull Factors
Auto Match Pull Factors is available from the
session Timecode Rate menu in the Session
Setup window (In Pro Tools 6.4, this menu is la-
beled Timecode Rate. In Pro Tools 6.2 and be-
low, this menu is labeled Frame Rate). When
In Pro Tools 6.4, the “Limit Pull Ups to
NTSC/PAL Film Standards” option has
been removed. NTSC/Pal standards appear
in bold in the list of all available pull up
options.
