Adobe Ultra is a vector keying application, distributed as a component of the Adobe Creative Suite CS3. Ultra utilizes image analysis technology to produce high quality chroma key effects in less than ideal lighting environments. Ultra also includes virtual set technology, which allows the keying of a subject into a virtual 3D environment. Ultra was acquired with the Serious Magic company, which Adobe purchased in 2006. Unlike many of the other applications in the Adobe Creative Suite, Adobe Ultra only runs on the Windows Operating System.
