None/Weave
The None/Weave option (Figure 6-30) is the
simplest algorithm, with no processing or
advanced frame/field detection. Instead, it
"weaves" each pair of fields together, treating them
as a progressive frame. This option is best for
material that shouldn't really be treated as
interlaced, such as SD footage shot in non-
standard, progressive recording modes, such as
the"30p" mode found on some cameras.
Detect Pull-down
Use the Detect Pull-down option (Figure 6-30) if
the source footage already has either 2:3 or 2:3:3:2
pull-down inserted (due to a telecine transfer, the
"24p" record mode of some cameras, etc.) The
V4HD will auto-detect the cadence of the pull-
down and assemble frames accordingly.
Upconversion deinterlacing and 23.976 frame
rates
The Upconversion Deinterlacing mode is ignored
if the HD frame rate is 23.976. In this case, the
V4HD attempts to detect and remove pull-down.
Upconversion Sharpness
Adjust Upconversion Sharpness (Figure 6-29) to
further improve the deinterlaced HD image. This
control determines the amount (in arbitrary units
from 0.00 to 1.00) of an unsharp mask applied to
the image while upconverting.

INPUT

The Input tab (Figure 6-31) provides several
settings for adjusting the Brightness, Contrast and
Hue of the incoming Composite or S-Video (SD)
signal.

THE GENLOCK LED

The genlock LED (Figure 6-1) indicates when the
V4HD has successfully genlocked to one of the
following sources:
the video signal being received from the
■
currently chosen input in the Video Source menu
(Figure 6-3 and Figure 6-5)
the Playback Clock Source (Figure 6-27 and
■
Figure 6-28)
the Video REF input (see "Video sync
■
connections" on page 27)
If the Auto Detect Input Format option (page 48) is
set to Manual, the genlock LED will always be
illuminated.

THE DEVICES MENU

The Devices menu provides a shortcut for
launching the MOTU Audio Setup application. If
you have multiple MOTU video interfaces
connected, it also lets you choose which interface
you are currently controlling with the MOTU
Video Setup software.
