Section 3 — Switcher Concepts
Input Shaped and Unshaped Video
Video coming into a switcher may or may not already be shaped,
depending upon its source. The Configuration Menu has a
selection for you to define whether the source video for each video
input is shaped or unshaped. This is what tells the switcher how
to process the signal.
If you incorrectly identify the type of video in the Configuration
menu—that is, if you select shaped when you should select
unshaped, or vice versa — your keys will have dark or light halos
at the edges.
Output Shaped and Unshaped Video
In addition to the input shaped/unshaped selections, there are
output selections that allow you to set the switcher output for
either shaped or unshaped fill video. Shaped video is the
preferred setting if the designation device can accept it.
Refer to the Shaped and Unshaped Video text in the Appendix
section of this manual for more information.
