Datamosh vs Glitch
データモッシュ / グリッチ
The image breaks apart, the colors slip out of register, and rectangular fragments scatter across the frame in both.
How to tell them apart. Glitch works in one still frame. Datamosh drags the previous picture along the motion until it melts and runs.
Datamosh
Deliberately breaking a video's keyframes so that the previous image is dragged along and dissolved by the next motion. The technique turns the inner workings of the compression algorithm into an aesthetic.

Refuses to hide error and corruption, exposing the fragility of the digital medium itself.
| Datamosh | Glitch | |
|---|---|---|
| Era | 2005– | digital |
| Family | Digital Image Techniques | UI Expression |
| Kind | Technique | Style |
| Cues | Melting, flowing frames / Macroblock debris / Motion vectors dragging pixels / Compression exposed | Channel shift / Block noise / Scanlines / Dropout |
| Best used for | Music video where the cut itself becomes the spectacle and dissolves · Showing clouded memory or consciousness through how the image breaks | Expressing uncertainty and system failure · A jolt of tension in music and video |
| Type | Let type read for a few frames before the melt, then release it | Partially corrupt a monospace or plain sans |
| Composition | Shoot both clips with matching motion to control the drag direction | Build the healthy composition first, then break part of it |
| Material | Set compression first and choose keyframe intervals as a creative call | RGB shift, compression noise, missing pieces |
| Caution | Melting the whole piece so nothing is ever recognizable, leaving no intact image for the collapse to work against. | Perpetual glitch loses meaning. Stage the difference between normal and broken. |
