Output Master: Color, Brightness, and Contrast
Red, Green and Blue color channels present in the output may be adjusted in both a subtractive and additive fashion.
The Brightness and Contrast of the imagery in the output may also be adjusted.
Output Master: Output Effects
The Output Effects are pulled from the shader-based texture effects (1-220) that may be used on each layer. The effect
will be applied only across the imagery in the output, not affecting imagery on layers or other outputs. Mbox v4 expands
the flexibility of effects by allowing for up to five modifiers.
Output Master: Camera
The Output Camera modifies the 3D perspective viewpoint for only the output it is applied to, allowing a virtual camera
position and look-at point for that camera. 3D objects that are visible within the boundaries of the output will be
rendered using the perspective of the camera.
Note: Multiple outputs can each have a camera applied to them, allowing for projection mapping onto multiple objects,
or onto the same object but from different perspectives.
Output Master: Geometry
The Output Geometry Fixture controls may be used to modify supplemental 2D rendering parameters for only this
output, not affecting any other outputs from the server. None of the output geometry controls affect the 3D perspective
of object rendered on the output.
Output Master: Keystone
The Output Keystone Fixture controls are used to enable and modify keystone and edge-blending parameters for only
this output, not affecting any other outputs from the server.
Output Master: Shutter
The Output Shutter Fixture may be used to apply 2D shuttering that can obscure portions of the output, but which does
not affect any other outputs from the server. The shutters can be thought of as sitting between the composited imagery
of the output and the virtual camera that provide the view of the imagery.

Layer Fixture

The Layer Fixture in Mbox is where all playback of 2D and 3D content occurs. Images, movies, and objects are selected
and arranged to create the composite imagery that is then output from the server's video outputs. Each Layer's
functionality includes a set of base parameters for media selection and composition, plus effects to modify imagery, and
also volume control for audio on the layer, plus controls to set the timecode link time for movie content using a timecode
sync playmode.
Layer Fixture: Base
The core functionality of each layer is the display of 2D and/or 3D content. Content is displayed in 2D or 3D space
appropriately, and various parameters affect its opacity, how it looks (color, brightness, contrast), where it is placed,
how it is scaled and rotated. More advanced parameters affect blending between the layer and layers below it in the
rendering stack, and also affect assignment to mixes or image remapping configurations.
