Comparison Matrix
Due to the simplified nature of working with multiple layers, graphics systems have relied on
Shaped keying for all compositing functions. Conversely, live DVE systems have traditionally
used unshaped keying as applying effects to full screen video is easier in this domain.
The comparison matrix below summarizes some of the main differences between working in the
shaped and unshaped domain:
Shaped
Unshaped
Keying Process
Additive (Simple)
Multiplicative (More Complex)
Preview
Previewing video properly
displays transparency
properties.
Previewing video does not
display transparency properties.
(No soft borders).
Standardization
Most Graphics, Compositing,
and computer based systems
use shaped keying
processes.
Production
Switches
Most modern switchers
support shaped keying.
However, some older
analog switchers only
support unshaped keying.
Most switchers support
unshaped keying.
