FOR-A to showcase advanced chroma keyer, video wall production system

Video and audio technology company FOR-A will introduce two products that allow broadcasters to deliver more powerful 3D effects and augmented reality in booth C5117 at this year’s NAB Show.

In the virtual studio display area of the booth, FOR-A’s most advanced chroma yeyer, the ACK-3000, will showcase realistic 3D effects yet, creating live keyed shadows in the composite image.


The ACK-3000 is a multi-format chroma key processor that generates a virtual human keyed shadow to provide realistic form and depth for live composite video. A product of the company’s continuous series of improvements in composite image technology, the one RU solution automatically adjusts the shadows to match the subject’s movement, applying a proprietary algorithm developed by FOR-A for this product. The unit creates two types of 3D shadows — under the feet and under the entire body— with built-in color correction to match the two composited images.

Full-featured settings for cameras, objects, lights, chroma key, color correction and feed track deliver powerful control for enhanced realism in the composite images. Users can add up to three light sources, and adjust the position, direction and diffusion, shadow intensity and color of each. Also selectable are the position, direction and size of shadow for up to three objects, as well as the foreground image brightness and tint, and the size and intensity of shadows under the feet.

Meanwhile, the sports production area will feature the company’s new Flexavision video wall production system that integrates several FOR-A products together to create seamless, high-resolution video and graphic displays over multiple, large-scale monitors in real time. Flexavision combines features of the company’s integrated image processing technology for live use in sport stadium and special event staging applications, and at NAB will be integrated with Click EffectsCrossFire and Blaze products, a highly regarded line of powerful but cost-effective and user-friendly digital content delivery systems, designed to meet the stringent demands of live sports and broadcast presentation environments.
