Chromatte fabric is designed to work in conjunction with a LiteRing. The LiteRing features Light Emitting Diodes (LEDs) that are arranged in a circular casing that is positioned in front of the camera lens. This provides all the light required to illuminate the Chromatte background for chroma key production. LiteRings are available in green and blue and in three sizes to fit different size lenses. Each size has a series of adapters to ensure maximum compatibility. These specially designed adapter rings simply screw into the filter thread on the front of the lens and then the LiteRing is placed on to the adapter and locked with a single screw, significantly reducing the set-up time associated with conventional chroma key.

Logical and simple to operate, Ultimatte DV offers the user unrivalled control over the matte parameters. The operator can quickly compare the input, the matte and the composite output via a single monitor connection. Internally generated test signals ensure the highest quality output is maintained. An internal frame store allows non-synchronous signals to be combined – a big advantage as many Dv cameras do not have genlock – and also allows the user to store a background frame in memory. The unit also functions as a transcoder, enabling the user to convert between video formats. On location, Ultimatte DV can be used as a pre-visualisation tool, enabling the director and crew to evaluate the first composite, rather than only seeing the camera feed on a preview monitor.
