MOTU V4HD User Manual page 49

1080PsF29.97 input. The signals are identical but
will be interpreted differently by the V4HD's down
converter, so in a case like this, you can choose
Genlock and then specify the incoming format
manually in the HD and SD Output Format menus
(Figure 6-3), as explained in "SD/HD output
format" on page 46.
Format and Genlock
The Format and Genlock option (Figure 6-19)
causes the V4HD to fully detect both genlock and
the video format for the current video source.
SDI Output Timecode Format
Use the SDI Output Timecode Format menu
(Figure 6-19) to specify the form of embedded
time code to include in the V4HD SDI output
signal. Choices are LTC, VITC 1 and VITC 2.
480i Component Analog Format
The 480i Component Analog Format option lets
you specify the voltage level standard for the
V4HD's SD component inputs and outputs when
running at 480i (NTSC). Choices are: EBU N10,
Sony Beta, Sony Beta Japan and Panasonic MII.
Choose the format that best matches the device(s)
connected to the SD component input and output.
Full Raster mode
The V4HD goes into Full Raster mode when you
specify Apple ProRes as the video format for your
Final Cut Pro project. More specifically, the V4HD
goes into Full Raster mode when you choose a
ProRes sequence, capture or playback preset, or
when you specify V4HD (or MOTU) Full Raster
for video input or output (as demonstrated in
Figure 7-4 on page 60). When you are working
with full-raster video, make sure the Full Raster
mode (Figure 6-19) matches the FireWire
connection you are using between the V4HD and
the computer.

FireWire 800 HQ
If you are using FireWire B, choose the FireWire
800 HQ setting. This option is only present in the
menu when the V4HD is connected to the Mac via
FireWire B operating at 800 Mb/s. It is not available
when FireWire A (400) is being used. This option
produces the best possible video quality for full
raster capture and playback with ProRes or any
other other high-quality HD codec with
compression characteristics similar to ProRes HQ
(a compression ratio of approximately 6:1).
FireWire 400 HQ
If you are using a FireWire A connection, choose
FireWire 400 HQ. This setting provides high-
quality full raster video capture and playback over
a FireWire A, along with at least eight channels of
48 kHz audio. This setting produces the best
possible video quality when circumstances require
the use of a FireWire 400 (FireWire A) connection.
This setting is also permitted when using FireWire
800, and could be used to free up FireWire
bandwidth for other daisy-chained devices or
additional banks of audio.
FireWire 400
The FireWire 400 setting is similar to the
FireWire 400 HQ setting above, except that it allows
for up to three 8-channel banks of 48 kHz audio (or
one 8-channel bank of 96 kHz audio) over a
FireWire 400 connection.
Timecode Source
The Timecode Source menu (Figure 6-19) lets you
specify which time code source you would like the
V4HD to resolve to: Sony 9-pin (via the RS-422
port), the LTC jack on the rear panel of the V4HD,
SDI (embedded) time code from the SDI input
currently chosen in the Video Source menu
(Figure 6-3 on page 43), or SD VITC (vertical
interval time code) from the currently chosen SD
source input.
