Databending vs Datamosh
データベンディング / データモッシュ
Both sit in Digital Image Techniques, so the question is not what they belong to but how they behave. They are reached for with some of the same intent, which is where they get confused.
Databending
Databending edits image or sound files with tools not intended for their format, turning a decoder's misreading into the work; file structure, compression and edit position determine its bands and color shifts.
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.

|---|---|---|
| Era | 2000s– | 2005– |
| Family | Digital Image Techniques | Digital Image Techniques |
| Kind | Technique | Technique |
| Cues | Sections of an image displaced into horizontal bands / Separated color channels and unexpected saturation / Local compression blocks that leave the source visible / Row-like fractures repeating from the edit point | Melting, flowing frames / Macroblock debris / Motion vectors dragging pixels / Compression exposed |
| Best used for | Showing the fragility and format-dependence of digital files through the damaged image · Colliding source imagery with decoder error in video, covers and posters | Music video where the cut itself becomes the spectacle and dissolves · Showing clouded memory or consciousness through how the image breaks |
| Type | Add copy after bending, or displace only part of a duplicate headline along the same axis. | Let type read for a few frames before the melt, then release it |
| Composition | Preserve one identifiable point and use the fracture direction as a compositional axis. | Shoot both clips with matching motion to control the drag direction |
| Material | Duplicate the file, protect its header and edit only payload data through another format's editor. | Set compression first and choose keyframe intervals as a creative call |
| Caution | A glitch overlay is not databending. The way one format was deliberately misread must determine the result. | Melting the whole piece so nothing is ever recognizable, leaving no intact image for the collapse to work against. |
