Shaped and Unshaped Video
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 Application Note in the 
Appendix section of this manual for more information.
