8-Input Universal Live Event Scaler/Switcher/Warp & Blend for Projection & LED Videowalls


FREE Shipping on orders over $100

The VP-794 is a high-performance switcher/scaler/edge-blend & warp for analog and digital video signals developed specifically for driving large screen displays and multiple screen applications from video or graphics sources. It up- or down-scales the incoming signal, processes the image with HQV and flexible warping, geometry correction and professional grade edge blending and outputs the signal to 3G HD-SDI, DVI/HDMI, VGA and S/PDIF connectors. VP-794 includes a special mode for driving LED video walls with pixel-accurate output image sizing.

Features & Benefits

  • Optimized Operating Modes - For LED video walls, or soft edge-blend and warp for projection, or scan conversion/scaling for general purpose scaler/switcher use.
  • Full Warp Mapping - Easy warp map creation for stacked projector alignment and curved screen multi-projector tiling via an included PC application.
  • Powerful Geometry Correction - For off-axis projection, pin/barrel and image rotation, pan, tilt and zoom.
  • Edge Blending - 4-sided professional grade edge blend with 48-bit processing, degamma & multi-region black level correction.
  • Genlock (V-Lock) - Accepts bi-level, tri-level sync or black & burst.
  • Multi-Standard Support - For CVBS & YC in PAL, NTSC, SECAM formats with selectable 3D comb for composite.
  • Superior De-interlacing - Motion adaptive per pixel video de-interlacing with multi-directional diagonal de-interlace filter reduces HD & SD image flicker and artifacts.
  • Selectable Lock Modes - Genlock (V-Lock), I/O lock or frame rate conversion.
  • Flexible Colour Calibration Controls - RGB Gains, RGB Cut-Off/Black Level, Saturation, Hue, Brightness, Contrast controls, Gamma selection with separate calibration memories per input channel.
  • Live Image Capture - Logo/still/backdrop capture with full scale warp/blend of the captured image, 4 memories.
  • LED Videowall Mode - Superb video down-scaling to as low as 128x96 pixels.
  • Multi-Format Operation - 3G HD-SDI, HDMI, DVI, computer graphics, component, composite and s-Video inputs for signals up 1080p & WUXGA.
  • HQV Video Processing - HQV (Hollywood Quality Video) processing represents the state-of-the-art in video processing technology, with the highest quality de-interlacing (with 3:2 & 2:2 pull down), 4D motion adaptive SD noise reduction and outstanding scaling performance for both standard-definition and high-definition signals.
