CONFIGURING THE VIDEO CONTROLS
The Video menus are used to configure parameters associated with the input and output video standards
and output video timing. The chart below shows the items available in the Video menu. Sections 6.3.1 to
6.3.3.5 give detailed information about each of the menu items.

6.3.2. 3:2 Pulldown Processing
When using a 1080i/59.94 input video feed containing 3:2 pulldown, the 7712HDC must be operated in
Field Mode in order to minimize motion artifacts. In Field mode each field of the incoming image will be
downconverted to one field of output image, so there will be no pulldown related de-interlacing artifacts on
film originated material with 3:2 pulldown, or video originated material acquired at a nominal 24 frames per
second.
When using a 720p/59.94 input video feed the 7712HDC will operates in Frame Mode where each frame
of the incoming image will be downconverted to one field of output image, so there will be no pulldown
related artifacts on film originated material with 3:2 pulldown, or video originated material acquired at a
nominal 24 frames per second.
7712HDC-12
Selects the video input and output standards.
Selects the reference source when 3:2 pulldown is being added on the
output. (7712HDC-SN-EAES4 version only)
Sets the offset of the A Frame from the Pulldown Reference when 3:2
pulldown is being added on the output. (7712HDC-SN-EAES4 version only)
Sets the vertical phase of the output signal to the NTSC Genlock reference
input.
Sets the horizontal phase of the output signal to the NTSC Genlock
reference input.
Sets the vertical phase of the output signal to the PAL Genlock reference
input.
Sets the horizontal phase of the output signal to the PAL Genlock reference
input.
Sets the offset in frames between colour frame 1 of the NTSC output signal
with respect to colour frame 1 of the NTSC Genlock reference input.
With this control, you can set the input and output video
standards.
Note: When set to Auto, the module can not distinguish between
1080i/59.94 and 1080p/29.97sF, so it will be treated as
1080i/59.94. Similarly 1080p/25sF will be treated as 1080i/50.
Note: 1080p/23.98sF not supported on S version.
