Datamosh vs Glitch
データモッシュ / グリッチ
Datamosh comes from Digital Image Techniques and Glitch from UI Expression. One is technique and the other style. They are reached for with some of the same intent, which is where they get confused.
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.
Glitch

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. |
