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:

Most Graphics, Compositing,
and computer based systems
use shaped keying
processes.
Most modern switchers
support shaped keying.
However, some older
analog switchers only
support unshaped keying.
