Slit-Scan Video Experiment

This is a slit-scan video experiment created by Andrew Hazelden. Wildflowers were filmed rotating around on a lazy susan. The footage was then processed on my Mac using a custom SDL based program written in C-code. This technique is also known as Chronotopic Anamorphosis or Digital Peripheral Streak Photography.

Hey man, great job! Do you mind explaining how you achieved this effect?

[AndrewHazelden]

@BennnnJ Basically you take the same single scan-line from an entire sequence of video that records the 360° degree rotation around an object. Next a new frame is created that is the composite of all of the extracted scan-lines. Then you increment down one row and start again. You can scan horizontally or vertically. When you extract horizontal scan-lines you get a spiral effect and vertical scan-lines get the refracted look. You can also extract scan-lines with a time offset for a skew effect.

@AndrewHazelden Ahh, groovy.

@waylandbell I worked with a homemade c-code based program using the SDL graphics library. I had some problems however with SDL and 64-bit on the Mac. It is possible to do the same thing with a copy of After Effects or using the Processing language.
