Glitch ============================================ A glitch is a fault or bug in a system. In the case of video and images it usually is caused by corrupted data, interference in the signal or software bugs. These faults can come up as displacements of pixels, colors or areas stretching/shrinking. In old tube like screens it can come up as a horizontal displacement or a specific distortion in one or more of the RGB channels. It's often used in Motion Graphics, and sci-fi scenes. .. note:: I've exaggerated the effects in this images so you can see more clearly what they do. In real uses you will probably want to be more subtle and use lots of masks. .. raw:: html
.. rubric:: Toolkit These nodes are designed to work together to create the overall effect. Think of them as building bricks. .. raw:: html

Can be used to simulate corrupted pixels. .. note:: You can use negative values in the scale settings, as well as in other nodes. This will push pixels the opposite way. ============================= ================================================= Inputs Description ============================= ================================================= Scale X Width of the distorted pixels Scale Y Height of the distorted pixels Fill How much of the area to fill Animation Offset Offset to animate the effect ============================= ================================================= ======================= ======================================================== Outputs Description ======================= ======================================================== Mask Black and white mask ======================= ======================================================== .. raw:: html

.. rubric:: Presets These nodes are built on the previous *toolkit* nodes. They are meant to be an example of how to use the toolkit nodes together. You can use these nodes as they are, but you will often find it more flexible to use the toolkit nodes directly in your compositions. .. raw:: html

Simple Glitch -------------------------------------------------------------------------------- .. image:: _static/glitch/simple.jpg A simple version of the glitch effect, aimed at getting better performance. It doesn't include any channel distortions. Includes Pixel and Pixel mask. ============================= ================================================= Inputs Description ============================= ================================================= Image Original image Large Distortion Scale Size for large pixel distortions Large Distortion Influence Intensity of large distortions Small Distortion Influence Intensity of small distortions Small Distortion Width Width of small pixel distortions Small Distortion Height Height of small pixel distortions Small Distortion Fill Fill of the pixel mask for small distortions Animation Offset Offset to animate the effect Mask Mask out areas of the effect ============================= ================================================= ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ======================================================== Complex Glitch -------------------------------------------------------------------------------- .. image:: _static/glitch/complex.jpg The full glitch. Includes distortions on individual RGB channels. Includes Pixel mask, Pixel, Bulge and Lines. ============================= ================================================= Inputs Description ============================= ================================================= Image Original image Influence on Red Channel Intensity of distort in the Red Channel Red Channel Distortion Amount of Red channel to cover with distortion Influence on Green Channel Intensity of distort in the Green Channel Green Channel Distortion Amount of Green channel to cover with distortion Bulge Influence Intensity of Bulge Bulge Position Position (in Y) of Bulge Bulge Blur Soften the bulge Large Distortion Influence Intensity of large distortions Large Distortion Scale Size of large distortions Line Stretch Influence Intensity of horizontal stretching Line Stretch Fill Amount of image to cover with stretching Animation Offset Offset to animate the effect Mask Mask out areas of the effect ============================= ================================================= ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ======================================================== Glitch (old) -------------------------------------------------------------------------------- .. image:: _static/glitch/old.jpg .. note:: This is the old glitch effect from Enhance v1. It doesn't use any of the **toolkit** nodes. Simulates the glitching effect of a corrupted video file. If you want to further customize, open the node group and tweak the values in the "Mask Creation" Frame. You can animate the Base offset property to animate the Glitch without affecting the displacement intensity, although it's recommended to do both. ========================= ======================================================== Inputs Description ========================= ======================================================== Image Original image Intensity Strength of the effect Displace 1 X/Y Width and Height of the first displacements Displace 2 X/Y Width and Height of the second displacements Displace 3 X/Y Width and Height of the third displacements Base Offset Offset to animate the effect Mask Mask out areas of the effect ========================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ========================================================
