fill the unused portion of the frame on either side
(Figure 6-13). No cropping occurs and the full
image is preserved.
14:9 Pillar Box (SD to HD)
With the 14:9 Pillar Box option (Figure 6-12),
aspect ratio is preserved (Figure 6-14) and some
cropping occurs on the top and bottom edge, but
not as much as in Full Screen mode (explained
below). In addition, the pillar box bars are smaller.
In essence, this mode scales the image larger than
Pillar box mode, but not as much as Full Screen
mode, with less top- and bottom-edge cropping
than Full Screen mode and smaller pillar box bars.

Full Screen (SD to HD)
The Full Screen option (Figure 6-12) preserves the
aspect ratio of the SD image, but it scales it propor-
tionally to fill the full width of the HD frame
(Figure 6-15). As a result, the portions of the SD
image that fall outside the frame (along the top and
bottom edges) are cropped. But the full width of
the HD frame is used.

Anamorphic (SD to HD)
The Anamorphic option (Figure 6-12) does not
preserve the aspect ratio of the SD image. Instead,
it scales the image to fill the full width of the HD
frame, but it also distorts the SD image vertically so
that expands to fill the HD frame (Figure 6-16). As
a result, the entire SD image is preserved, but it
appears horizontally expanded.

SD/HD output format
The SD output format and HD output format blocks
in the signal path diagram (Figure 6-3) indicate the
specific format and frame rate that the V4HD is
currently converting and sending to its SD and HD
outputs. If the “Auto Detect Input Format” option
(page 48) is set to Manual or Genlock, these blocks
turn into menus from which you can specify the
format being captured and converted from the
source currently chosen in the Video Source menu
(Figure 6-3). When the “Auto Detect Input
Format” is set to Format and Genlock, depending
on the situation, these menus will let you choose
the output format for the non-source path. For
example, if you currently have an SD source, this
menu will let you choose the HD output format.
☛ SD output is disabled when the HD frame rate
is set to 24, 30, or 60 (as opposed to 23.976, 29.97,
or 59.94).
Destinations
The Destinations on the far right of the signal path
diagram (Figure 6-3) display where the HD and SD
video signals go.
HDMI/DVI
The HDMI/DVI menu (Figure 6-3) lets you choose
the output format for the HDMI output on the rear
panel of the V4HD. If you choose DVI, you’ll need
an HDMI-to-DVI cable or adapter.
