   Note

   A studio term built from two plain parts: chroma, meaning color, and key, the cue that marks where one picture gives way to another. Broadcasters and filmmakers use it as an uncountable name for the technique (shot with chromakey) and also as a countable noun for a single setup (two chromakeys in one studio). The verb, the editing action itself, keeps the spelling closed: chromakeyed, chromakeying.
