The Model 4000 production switcher advances the state-of-the-art for post production and live broadcast, utilizing component 4:2:2 digital signal processing for superior image quality and fidelity. Your system can also be configured for any combination of video and key inputs providing total flexibility. You can add up to 64 inputs for video and/or keying.

Three Powerful Versions

The 4000 Series production switchers eliminate many of the start-up costs and recurring maintenance expenses that are common with analog technology. With the combination of component video, advanced digital signal technology and sophisticated keying power, your creativity is infinite.

  • Unlimited effects re-entry of all M/Es

Model 4000-3T
Remote Live Broadcast Power

  • Provides the same features as the Model 4000-3 plus the flexibility of separate sub-panels which fit easily into extremely tight spaces, such as mobile applications.

Effects Send Capability in each M/E

With Effects Send, you can feed digital effects devices like the Grass Valley Krystal 4300 with video and key sources from any Model 4000 M/E keyer. You can use the Effects Send system to "splice" the Krystal system into the M/E between the keyer and the compositing circuits, saving an additional keying operation.

Lamina Image Layering

Each M/E system includes two modes of operation. The traditional mode allows two foreground keys, with exchangeable priority, to be composited over the backgrounds. Lamina Image Layering mode allows 4-layer compositing within each M/E. The composited key from an M/E in the layering mode is available as a source or another M/E or the DSK for additional compositing.

Full Additive Mix

Six dual matte generators are included in each M/E. These provide independent color matte fill for the foreground keyers, Borderline® key edge generator and preset wipe borders. Each M/E includes a Full-Additive Mix (FAM) mode. FAM allows all four layers to be additively mixed together.

Advanced Emmy Award Winning E-MEM System with Key Framing

The E-MEM Timeline system is a very powerful tool in the development of complex effects. Time Align is one component of the system that makes it easy to move one element relative to another. You do not have to think about keyframe duration, calculations or adjustments. Simply move the elements visually, align it and all calculations happen automatically. The Model 4000 displays any timeline forward and backward independently or in any grouping as you build the effect. The standard E-MEM system provides storage for 100 complete switcher effects, and a 3.5" floppy disk drive is included for storage of E-MEM effects set-ups.

Pristine Chroma Keys and Borderline Key Edging

The foreground keyers can be enhanced with Chromatte Chroma Key. Advanced chroma key capabilities include background and foreground suppression and the Grass Valley patented Secondary Hue Suppression process to eliminate color fringing. All the keyers have their own individual matte generators and you can fit them with another Grass Valley exclusive - Borderline key edge generators.

Video, Key and Mask Framestore

You can precisely grab a video with its key signal to make layering of stills quick and easy. You also get a positionable drop shadow, real time video bit map effects, write after read, independently adjustable crop on video and/or key. The maskstore provides the ability to draw "garbage" masks into storage. And, the framestore and maskstore functions can be controlled by the E-MEM system.


Model 4000-2

Wipe System with Extensive Set of Patterns

This feature includes patterns that can be modified with rotation, pattern split, border width, border symmetry, border opacity, edge softness, aspect, vertical and horizontal multipliers, modulation and a rate controlled pattern positioner. A texture pattern allows the creation of randomized noise for unique textures. An optional Secondary Wipe Generator provides additional wipe pattern flexibility, such as pattern
mix, within the M/E.
