Matte Input Settings
Blackmagic Ultimatte 12 can accept 4 different matte inputs, each assigned to a specific function.
These 4 matte inputs are:
Background matte
‚
Garbage matte
‚
Holdout matte
‚
Layer matte
‚
Background Matte
The background matte is associated with certain elements in the background scene that need
to be treated as their own layer. By converting these background elements into layer elements,
they can be moved in the layering order in front of the foreground objects. These background
elements that are converted to layer elements can only be opaque elements.
Garbage Matte
The garbage matte is associated with the boundaries of the foreground screen. It is used to
artificially extend the screen area, so that the background scene can be added in these areas.
The garbage matte should have a large soft transition area, from black to white, so that the
garbage matte blends better with the real screen area.
If foreground objects enter these soft transition areas of the garbage matte, these objects will
gradually become transparent and mixed with the background scene until they are fully
faded out.
In an alternate process, Blackmagic Ultimatte 12 can gradually apply the garbage matte clean
up function in the soft transition areas so that the foreground objects can still enter these
transition areas without becoming transparent.
Holdout Matte
The holdout matte is associated with elements of foreground objects which have similar colors
as the screen color. The holdout matte can be used to prevent these portions of foreground
object areas with similar color as the screen from becoming partially or fully transparent.
Additionally, the holdout matte can be used to retain or remove the foreground object colors
that are similar to the screen color.
Layer Matte
The layer matte is associated with the 'layer in' elements. The layer matte is used to determine
the opacity of the corresponding 'layer in' source. The layer elements associated with the layer
matte could be opaque or can have varying levels of transparency with different colors.
Window
The window setting lets you create internally generated mattes that can be set with rectangular
only proportions. Enable window by tapping the 'window' button, then set the input source you
want to apply the window to by tapping on the respective matte button in the functions section
of the touchscreen.
