Layering
Layering
Lamina™ Video Compositing is a feature that enables up to four
video layers to be composited in a single mix/effects system. The
composite image can then be used as a key source or a
background in another mix/effects system or the downstream
keyer. This allows multiple-layer effects to be created in one
recording pass.
Layering is enabled on an M/E-by-M/E basis in the M/E Mode
Menu.When enabled, the A and B buses function as keyers rather
than background buses; thus, four keyers are available—Key 1,
Key 2, Background B, and Background A. Operations in layered
mode can affect any selected layer or combination of layers.
Priority of the layers is as follows: Background B and Background
A have fixed priorities—Background B has the least priority
(bottom layer) and Background A has the next-to-least priority
(next-to-bottom layer). The priorities of Key 1 and Key 2, the top
two layers, can be selected (toggled) with the
KEY PRIORITY
button. The key OVER indicators show which of these two layers
is on top.
In layered mode, the background keyers (B and A) do not have
the following functions: Borderline capability, mask capability,
and chroma keying.
