FS4 Frame Synchronizer/Converter v1.1
1 Background Fill This parameter selects the background source used to fill any part of the processor
output raster not filled with video from the main input video. For example, when the
Video Output Mode selection is Sidebars, this parameter selects the video source for the
Sidebars.
2 Sidebar Edge The parameter adjusts the sidebar position where the center video meets the pillarbox
background video on both sides. The underlying hardware feature is the same as Custom
Right Crop and Custom Left Crop. This is effectively an extra handle on the Left Crop and
Right Crop parameters.
The Crop and Sidebar Edge controls are additive; increasing Sidebar Edge (making the
sidebars larger and the center-video smaller), equates to setting Left and Right Crop
values to smaller percentages. The Sidebar Edge can be set to 0 through +128. A value of 0
produces a 4:3 center. Positive values produce wider sidebars (and a narrower center).
11.1 Matte Luma This parameter determines the Matte Luma level of the background fill.
11.2 Matte Chroma This parameter determines the Matte Chroma level of the background fill.
11.3 Matte Hue This parameter determines the Matte Hue of the background fill.
NOTE: On the front panel, as you turn the Matte Hue ADJUST knob the values wrap from 359 back to
0 degrees.
TIMING Menu Group
IMPORTANT: In Four Channel Mode, the settings in this menu group apply only to the selected Video
Processor (VID1- VID 4).
These parameters adjust Video Processor horizontal and vertical output timing in
reference to the genlock source already selected, and permits adding up to 6 full frames
of output delay.
