Frame Rate; Reader Section - MOTU Traveler-mk3 User Manual

choose the SMPTE / SMPTE setting in the Clock/
Address menu. This means that the system will use
SMPTE as the clock (time base) and SMPTE as the
address.

FRAME RATE

This setting should be made to match the SMPTE
time code frame rate of the time code that the
system will be receiving. The Traveler-mk3 can
auto-detect and switch to the incoming frame rate,
except that it cannot distinguish between 30 fps
and 29.97 fps time code, or 23.976 and 24 fps time
code. So if you are working with either of these
rates, make sure you choose the correct rate from
this menu. The Traveler-mk3 driver updates the
frame rate setting in Digital Performer and
AudioDesk for you.

READER SECTION

The Reader section (on the left-hand side of the
window in Figure 12-1) provides settings for
synchronizing the Traveler-mk3 to SMPTE time
code.
Status lights
The four status lights (Tach, Clock, Address and
Freewheel) give you feedback as follows.
Tach
The Tach light blinks once per second when the
Traveler-mk3 has successfully achieved lockup to
SMPTE time code and SMPTE frame locations are
being read.
Clock
The Clock light glows continuously when the
Traveler-mk3 has successfully achieved lockup to
an external time base, such as SMPTE time code or
the optical input.
Address
The Address light glows continuously when the
Traveler-mk3 has successfully achieved lockup to
SMPTE time code.

Freewheel
The Freewheel light illuminates when the
Traveler-mk3 is freewheeling address (time code),
clock or both. For details about Freewheeling, see
"Freewheel Address" and "Freewheel clock" below.
SMPTE source
Choose the analog input that is connected to the
time code source. This is the input that the
Traveler-mk3 "listens" to for time code.
Freewheel Address
Freewheeling occurs when there is a glitch or
drop-out in the incoming time code for some
reason. The Traveler-mk3 can freewheel past the
drop-out and then resume lockup again as soon as
it receives readable time code. Choose the amount
of time you would like the Traveler-mk3 to
freewheel before it gives up and stops altogether.
The Traveler-mk3 cannot freewheel address
without clock. Therefore, the Freewheel Address
setting will always be lower than or equal to the
Freewheel Clock setting, and both menus will
update as needed, depending on what you choose.
Keep in mind that freewheeling causes the system
to keep going for as long as the duration you choose
from this menu, even when you stop time code
intentionally. Therefore, if you are starting and
stopping time code frequently (such as from the
transports of a video deck), shorter freewheel
times are better. On the other hand, if you are
doing a one-pass transfer from tape that has bad
time code, longer freewheel times will help you get
past the problems in the time code.
The 'Infinite' freewheel setting
The Infinite freewheel setting in the Freewheel
Address menu causes the Traveler-mk3 to
freewheel indefinitely, until it receives readable
time code again. To make it stop, click the Stop
Freewheeling button.
