12. KEY and FLEXaKEY
The key feature enables you to superimpose titles and images onto background signals. Four key
channels are provided for each M/E and four key types are available in all keyers: Luminance Key,
Full Key, Bus Key and Chroma Key. Key Invert, Mask and DVE effects can also be added to keys.
Furthermore, FLEXaKEY 1-4, whose background buses can be freely selected, are equipped as
downstream keyers.
KEY/FLEXaKEY features
M/E1 and M/E2 selection (re-entry)
(*1) Except when destination backgrounds are the same.
(*2) An ME Lite image displayed on FLEXaKEY buses, as a re-entry, is shifted below by one horizontal line.
This chapter describes the key setup and adjustment using M/E1 KEY1 as an example.
Luminance Key
Luminance Key, also called Self Key, uses the same image for Key Source and Key Insert. This
image is selected from Key Insert.
