Example: Developing effects with Visual Cortex System

This topic presents a process for development of a digital video effect as an introduction to one of many methods of keying, compositing, and colorizing. I will use the following modules along with an external video source, a glitch processor, and a video mixer:

  • LZX Visual Cortex
  • Teletect Visual Cortex Expander (not pictured)
  • LZX Doorway
  • LZX Fortress
  • LZX Curtain
  • LZX Memory Palace

The markings in CMY outline a system between each group. Each module is also a system individually. Consideration of system configuration can contribute to clarification of a system voice.

The following system extracts highlights for characterization with a video texture and the buffer. It is mixed in a WET/DRY configuration against a glitch processed track with a video mixer. The system is presented in a visual aim directed fashion as a patch below, and by linear step following the FAQ.


  • Do I need all of these modules to benefit from this thread?

The material is presented such that the user could recreate the basic functionality with an external source and the Visual Cortex only. The luma signal would bypass processing before the composite section. For users with some modules but not others, I have provided belay points in the process per module.

Building a DVE with Wet/DRY Glitch Processing

  1. Decoding and Keying an External Source
  • An external source is decoded into Channel A of the Visual Cortex. Note settings along indicated axis, disposition of LED indicators, and crossfader.

  • The luma output from VC’s input decoder is used to generate a key. (Note change in setting.)

  • The character of the keyer can be appreciated by changes of threshold and gain.

  1. Fill Key Foreground and Composite
  • ‘Highlight’ key is output to VC Composite input C, indicated on page 9 of Manual. Mix B. switch is on, confirmed by colorization.

  • A texture is output to foreground input of keyer, calibrated, and appreciated by hand in time lapse.

  1. Filtering Key for Edge Refinement and Softening
  • Highlight key with foreground texture is output to filter and presents edge highlights and softening.

  • The character of the filter at this range is appreciated by hand in time lapse.

  1. Colorizing and Compositing in Visual Cortex
  • Presentation of VC Channel B colorization:

  • Feedback is demonstrated by VC Expander RGB output to VC Channel B RGB input.


  • Colorization is applied to taste.


  • The external source is auditioned to appreciate the effect, here as 2fps timelapse:

  • Letterboxing can be eliminated and points of interest can be framed
    by cropping prior to montaging.

  1. Key to DVE with Buffer, Spatial Processing
  • The effect is matured in the buffer and by spatial processing. (Signal chain from above through Memory Palace, Warp Mode, RGB, Luma Key. Monitored in single color channel of VC.)

  • DVE is adjusted to taste. Modulation of MP Contrast, Width, Center, and Position characterize and block the effect.


  • VC composite section is reconfigured to utilize DVE as VC composite input. Modulation of spatial processor is auditioned.


  1. Colorization for Glitch Processing
  • Colorization is applied to taste.

  • Glitch processing is applied to VC Composite video output, appreciated here as 2fps timelapse with selects.

  1. WET/DRY balance with video mixer
  • A video mixer receives the composite video output of both VC and glitch processing and creates a balanced mix.


  1. Final review and Download


  • Layers of video can be combined to create textures and effects.
  • Keying and filtering can assist in constraining textures and effects to areas of interest.
  • Processing video in a WET/DRY configuration allows for balancing or performance control with a video mixer.


That was quite a ride!!! Awesome documentation of process.
