STANDALONE OPERATION

STANDALONE VIDEO CONVERSION
The V4HD provides hardware-based conversion
features, which you can employ during standalone
operation. Here are a few examples:
■ You could up-convert SD to HD in the V4HD
hardware and then distribute it to all HD outputs.
Or you could down-convert HD to SD and
distribute it to all SD outputs.
■ You could connect a 23.976 fps input signal,
insert pull-down to 29.97 fps and send this signal
to all SD and HD outputs.
■ As demonstrated below in Figure 11-1, you
could choose SD component (in YPbPr format) as
your input source and distribute this input signal to
all SD outputs on the V4HD. At the same time, you
could also be converting it to 720p or 1080p 23.976
with 14:9 pillar box formatting on all of the V4HD’s
HD outputs.
These are just a few examples. There are many
possible conversion scenarios.
Conversion settings
You can program the V4HD’s conversion settings
using the front panel LCD. You can also use the
Capture/Convert Signal Path settings in the
MOTU Video Setup software beforehand, and then
disconnect the computer. The Capture/Convert
settings you make in the software are remembered
and remain in effect during standalone operation.
AUDIO ONLY MODE
To put the V4HD into Audio only mode:
1 Press the MENU button repeatedly until you see
the V4HD SETUP menu.
2 Press the left/right PAGE buttons to access the
AV Mode setting.
3 Turn the VALUE knob to choose Audio Only.
4 Push the VALUE knob to confirm your choice.
This turns the V4HD into standalone 24-channel,
12-bus audio mixer (16 channels and 4 busses at
the 4x sample rates). To control the mixer from the
front panel LCD, see “CueMix Menu” on page 99.
Figure 11-1: An example of standalone hardware distribution and conversion. The V4HD source input is set to SD
component YPbPr. The V4HD hardware is distributing this input signal to all outputs and simultaneously converting
it to 1080p23.976 with 14:9 pillar box formatting for HD output.
