Ref Present, Locked, and Speed Cal Indicators
The Ref Present, Locked, and Speed Cal indica-
tors in the SYNC Setup section of the Session
Setup window display synchronization status of
the SYNC peripheral. The Locked and Speed Cal
indicators reflect the state of the same LEDs on
the front panel.
Ref Present Indicator The Ref Present indicator
lights when the Video Ref In connector is receiv-
ing a valid video signal.
Locked Indicator The Locked indicator lights
solid green when the SYNC peripheral is locked
to the selected clock reference. The Locked indi-
cator flashes yellow if the selected clock refer-
ence source is missing or out of lockable fre-
quency range.
Speed Cal Indicator This indicator shows the sta-
tus of the incoming clock reference:, depending
on the type of SYNC peripheral you are using:
• SYNC I/O
• Lit: SYNC I/O is locked and the clock refer-
ence is within 0.025% of the expected rate
• Flashing fast: SYNC I/O is locked but the
clock reference is more than 0.025% faster
than the expected rate
• Flashing slow: SYNC I/O is locked but the
clock reference is more than 0.025% slower
than the expected rate
• Unlit: Clock reference is not within 0.025%
of the expected rate
• SYNC HD
• Yellow Solid: SYNC HD is locked and the
clock reference is within 0.025% of the ex-
pected rate
• Yellow Flashing Fast: SYNC HD is locked
but the clock reference is between 0.025%
and 4% faster than the expected rate
• Yellow Flashing Slow: SYNC HD is locked
but the clock reference is between 0.025%
and 4% slower than the expected rate
• Red Flashing Fast: SYNC HD is locked but
the clock reference is more than 4% faster
than the expected rate
• Red Flashing Slow: SYNC HD is locked but
the clock reference is more than 4% slower
than the expected rate
• Unlit: SYNC HD is not locked to the chosen
clock reference
External Time Code Offsets
In the External Time Code Offsets section,
Pro Tools lets you compensate for devices that
are consistently offset by a fixed number of
frames (such as some color–corrected video mas-
ters), or for material that starts at a different
time than the session.
Pro Tools provides four different types of Exter-
nal Time Code Offset settings. These offsets in-
clude:
• MMC (MIDI Machine Control)
• 9-Pin (Deck Control)
• Synchronization peripherals such as the
SYNC HD, SYNC I/O, or other peripherals
(such as MIDI interfaces that provide MIDI
Time Code).
• Satellite (Pro Tools with Satellite Link or
Video Satellite)
Unique values can be defined for each of these
types of offsets, or you can link all to adjust in
unison.
