Synchronization Preferences
Machine Control Section
Machine Chases Memory Location When se-
lected, navigating to a specific location in a session
with a Memory Location causes a connected trans-
port to chase to that location.
Machine Follows Edit Insertion/Scrub When se-
lected, navigating to a specific location in a session
by moving the selection point or by scrubbing a
track will cause a connected transport to chase to
that location.
When the connected device is a linear device (such
as a tape deck), select
Linear Devices (jog) to set
Pro Tools to send jog commands.
When the connected device is a non-linear
device (such as a random-access video recorder or
another Pro Tools system), select
Non-Linear De-
vices (cue)
to set Pro Tools to send cue
commands.
Machine Cues Intelligently (Avid HDX,
Pro Tools|HD, and HD Native Systems Only)
When selected, if you navigate to a cue point that is
more than 10 seconds from the current location,
Pro Tools will command a connected transport to
fast wind to the new location at full speed to within
10 seconds of the cue point. Cueing will then slow
to normal speed until the point is reached. This can
significantly speed up tape cueing with certain
video transports.
Stop at Shuttle Speed Zero (Avid HDX,
Pro Tools|HD, and HD Native Systems Only)
Causes Pro Tools to send a Stop command when-
ever you stop shuttling. This is useful if you have a
machine that requires an explicit stop command to
park correctly.
Non-Linear Transport Error Suppression (Avid
HDX, Pro Tools|HD, and HD Native Systems
Only)
When Transport = Pro Tools, keeps
Pro Tools from sending a Stop command when
taken offline. This prevents Pro Tools from stop-
ping any other 9-pin devices connected to the sys-
tem.
Synchronization Section
Minimum Sync Delay Sets the initial amount of
prime time (in frames) your system’s devices need
to achieve synchronization “lock.” This amount
varies for each device. Pro Tools lock up delay is
set by entering a value for
Minimum Sync Delay in
the Synchronization page of the Preferences. The
lowest value available is 15 frames. Find the short-
est possible lock-up time that your equipment can
operate at consistently, and set this as the
Minimum
Sync Delay
. On systems using MachineControl,
enabling the
Use Serial Timecode option will
make machines lock up much faster. (Serial time-
code requires both a qualified synchronization pe-
ripheral and external devices to be locked to house
video reference.)
