MOTU SMPTE SETUP
The included MOTU SMPTE Setup™ software
provides a complete set of tools to generate SMPTE
for striping, regenerating or slaving other devices
to the computer when the V4HD is operating in
Audio Only mode (see "Enable Video" on page 50).
CLOCK/ADDRESS
The Clock/Address menu (Figure 10-1) provides
the same global Clock Source setting as in MOTU
Audio Setup ("Clock Source" on page 73), but it
includes additional information: each setting
shows both the clock and the address (time code or
sample location), separated by a forward slash ( / ).
To resolve the V4HD to SMPTE time code under
normal operation, choose the SMPTE / SMPTE
setting in the Clock/Address menu. This means
that the system will use time code as both the time
base and 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 V4HD can auto-
detect and switch to the incoming frame rate,
except that it cannot distinguish between 30 fps
Figure 10-1: SMPTE Setup gives you access to your V4HD's on-board SMPTE time code synchronization features.
88
The Reader section provides settings for
resolving to video and/or SMPTE time code.
and 29.97 fps time code, or 23.976 fps and 24 fps.
So if you are working with either of these rates,
make sure you choose the correct rate from this
menu.
READER SECTION
The Reader section (on the left-hand side of the
window in Figure 10-1) provides settings for
synchronizing the V4HD 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
V4HD has successfully achieved lockup to SMPTE
time code and SMPTE frame locations are being
read.
Clock
The Clock light glows continuously when the
V4HD has successfully achieved lockup to an
external time base, such as SMPTE time code.
The Generator section provides settings
for striping SMPTE time code.
