datamosh

Datamoshing is a glitch art technique that involves intentionally corrupting video files to create abstract, distorted visual effects. It exploits the way video compression algorithms work, specifically the difference between keyframes and inter-frames. Keyframes are complete frames, while inter-frames predict motion and only store the changes.

When a datamosh effect is applied, the data representing these predicted changes is often mixed up or repeated, leading to unpredictable visual artifacts. This can manifest as repeating patterns, shifting colors, object fragmentation, and a general breakdown of the original image. The process typically involves editing video files at a low level, often using specialized software or scripts that manipulate the raw data streams.

The resulting aesthetic is often described as digital decay or a visual representation of data corruption. Datamoshing can be used to achieve a variety of looks, from subtle distortions to extreme, abstract transformations of the source material. It has found a niche in experimental video art, music videos, and visual effects where a unique, broken aesthetic is desired. The unpredictable nature of datamoshing means that each instance can be unique, making it a popular tool for artists seeking to break away from conventional visual styles.
