ree different keying solutions for Crystal Visions CABSAT visitors (STAND B6-4)

Crystal Vision will be showing three different keying solutions on Stand B6-42 at CABSAT 2014, which takes place in Dubai between 11th and 13th March with these visual Crystal Vision products traditionally most popular with customers in the Middle East. Visitors can see how easy it is to create a realistic live virtual production using Crystal Visions latest chroma keyer, while also on show will be two station branding products designed for adding graphics to video sources.

The Safire 3 real-time chroma keyer has gained two new processing features (Shadow Density and Key shrink) which make it even easier to generate the best possible output picture. Working with 3Gb/s, HD and SD sources, Safire 3 is ideal for all live virtual productions from studio to sport. This 100mm x 266mm module uses an extremely sophisticated algorithm and an extensive range of fine-tuning tools for convincing edges, noise reduction, colour spill processing, lighting compensation and colour correction, and includes a framestore synchroniser and up to ten frames of delay on each input. Safire 3 can be operated using a choice of control options, including dedicated touch screen control panel (the Safire 3 Controller) and a web browser running on any device. The first new processing feature is Shadow Density, designed to make it easy to increase or reduce the appearance of shadows. It can be used to remove any shadows that have been cast on to background graphics by uneven lighting, something often required in news-type applications, or alternatively to increase the shadows to make the composite image look more real ideal for full length shots where shadows would be naturally cast on to the floor. The second new processing feature is Key shrink, a useful tool for enhancing edges by reducing artificial borders between the camera feed and background. Key shrink is user adjustable in 0.001 pixel steps from 0 to 1 pixel.

The MultiLogo logo keyer is a powerful branding tool for adding up to three graphics to HD or SD video sources, providing 4 GB or 8 GB of internal storage for up to 500 graphics. Features include numerous key processing controls, look-ahead preview, clip recording and trimming, Quick Text, the ability to store 255 partial presets and relay bypass protection. The latest version of MultiLogo is ideal for video and audio branding applications with its powerful new audio features: it can embed up to four audio groups into its video outputs, with audio mixing allowing this output audio to be generated from a mix of the audio embedded on the video input and a voiceover or sound effect sourced from either the two internal audio stores or from an external AES input. The voiceover or sound effect can be faded in and out and have its level adjusted, while the main programme audio can be partially or fully dipped allowing it to be either mixed with or be replaced by the voiceover. Audio and video cross fading is additionally available.

For more simple keying applications, LKEY 3 is a new linear keyer incorporating numerous features for a smaller price tag. Designed for keying one graphic over 3Gb/s, HD or SD video streams, LKEY 3 brings with it a number of new features appearing on a Crystal Vision linear keyer for the first time: it is the companys first 3Gb/s-compatible linear keyer, and features masks with adjustable edge softness, as well as a frame synchroniser on each input along with an additional ten frames of video delay ideal for matching any big system processing delays.

Also on show will be Crystal Visions full range of interface products. These include up and down converters with the picture quality that broadcasters standardise on, 2 x 2 fail-safe routing switches that guarantee a clean switch with a full framestore synchroniser on each input, and flexible embedded audio solutions that combine embedding and synchronising with Dolby encoding and decoding.

Based at Whittlesford near Cambridge in the UK, Crystal Vision provides digital keyers, picture storage modules and a full range of interface equipment including converters, decoders, encoders, distribution amplifiers and audio embedders to the professional broadcasting industry worldwide.
