In Z Vector, distortion is a great way to add dynamics to your visuals. Just as with animation controls, the distortion source can be either live audio analysis or synthetic beats (BPM/external clock based method). The L/H/N/B/4/8/16 controls work by creating dynamic, smoothly changing distortion waves.
The freq(uency) mode outputs FFT (i.e. the frequency composition of the audio signal). (Auto)corr(elation) mode, on the other hand, outputs a strong overall response for periodic audio signals. These two modes offer an alternative, more radical way to control the distortion effect as their output is applied to the 3D pixel grid directly for each frame (often with violent effects).
The center of distortion (relative to the shape and size of the pixel grid for both inputs) for all modes can be controlled with the X and Y controllers. Controls are also given for the shape, general direction as well as the scale and width of the distortion wave.
The balance controller can be used to mix the distortion effects from affecting only the background plane (which can be brought to fore / back using the aptly named controller on the input page) at value -100 to affecting only the foreground (everything else over the background plane inside the input mix – for example autofiltered people) at value +100. The default is a mix of both at controller value 0.
Congratulations! You’ve now successfully finished all three Basics level tutorial series. You should now have sufficient knowledge of almost all aspects of Z Vector that relate to creating visuals looks with the software and be able to apply them in live situations. For gaining more control over the software and the visuals, and to understand how you can make Z Vector work with your other tools and controllers, be sure to continue to the Intermediate tutorials (coming soon).
