If you do anything with it I’d love to see it!Įdit: The script was used to make this music video. It shouldn’t be too hard to use, details are in REAMDE.md.

On the bottom left is the image with sorted intervals.Īll the images in this article were generated using a pixel sorting script I wrote in python – source here.

On the bottom left is the image with the intervals filled in with random colors – each color represents a different interval.

Notice that the foam – too light – and the shadows – too dark – are outside the threshold.

The top right is the image with pixels outside the lightness threshold replaced with black, and the rest filled in with white.

The intervals are defined by regions of the image that are too light or too dark – the edges of these regions define the edges of the intervals. It was popularized (possibly invented) by artist Kim Asendorf (processing source code here). Pixel sorting is an interesting, glitchy effect which selectively orders the pixels in the rows/columns of an image. Kim Asendorf’s code simply applies this technique twice: first vertically, then horizontally. Pixel Sorting Introducing order in a disordered way can make for some great glitch art.

The pixels in each interval are rearranged so as to sort them with respect to some property, say, lightness.

The rows/columns of the image are split into ‘intervals’ (more on this later).

They propose using it as a technique for unsupervised classification, to be applied to images from remote sensing satellites. Neat! The earliest reference to pixel sorting I could find on the internet is this paper ( PDF) by scientists from Iraq’s Scientific Research Council. The processing script was cryptic and not very hackable, and I felt like something more lightweight was needed, so I wrote my own version in python – more info on GitHub.

AE Pixel SorterĪE Pixel Sorter lets you create and experiment with pixel sorting in After Effects with easeĪE Pixel Sorter was the first tool to bring the pixel sorting glitch effect available for motion designers and video editors within After Effects.Pixel Sorting Introducing order in a disordered way can make for some great glitch art. Have fun sorting!Īfter Effects Pixel Sorter is perfect for use in music videos, broadcast television, live performances, video games, and more. The core algorithm has been re-coded to make it faster and more intuitive, plus new additional creative and technical features. Version 2 of the plugin pushes this effect much further by allowing you to create more innovative visuals. Experimenting with Pixel Sorting just became so much easier!
