Layout View
A representation of the current layout is shown, with the SDI input raster
represented in red, the HDMI input raster represented in blue, and the graphic
layer represented by a rectangular grid. The display priority is shown with
appropriate overlaps. The background matte layer is colored cyan in this view.
The video confidence monitor, if displayed above, is a low frame rate
representation of the final layout, with the actual input video imagery and any
included graphic and the actual matte color.
Layout Config
Below the Layout View is a pane of layout configuration controls. Changes to
these settings are displayed above as the parameters are modified.
Layout Selection
The ten currently available layouts are listed by name in the scrolling pane on the
left. Clicking on a layout icon to the right of the name loads that layout for display
and adjustment.
Layers
The display order of the SDI, HDMI, and Graphic layers are listed from top to
bottom in the center of the pane. The display order of any layer can be changed
by dragging that layer up or down the list.
Show/Hide Layers
Each enabled input or graphic layer can be shown or hidden by clicking the eye
icon on the left. This is intended for use as a temporary aid for identifying the
layers during composition.
Center Layer
The arrows button on the right of each layer centers that layer horizontally and
vertically.
SDI Scale, HDMI Scale
The size of the SDI source and HDMI source input can be reduced with the sliding
scale, or by entering a reduction amount value. Range is 0.1680 to 1.000.
NOTE: The graphics layer is always full raster and centered, and cannot be resized,
cropped, or moved.
Active Layer
Selecting a Layer here provides access to additional parameters affecting only
that layer. These parameters are displayed immediately below (if that pane is
open), and vary depending on the layer selected.
• HDMI and SDI Layers
• X and Y Position, range -1.0000 to +1.000
• Crop Left, Right, Top, and Bottom, range 0.0000 to 1.0000
• Graphic Layer
• Graphic Image - Graphic file selection from the 20 available.
• Graphic Shaped - Select
On
or
Off
(default). Select On if the source graphic
is already shaped (multiplied by the key signal). An incorrect selection can
create dark or light halos at the edges of the key.
