Datamoshing works by intentionally corrupting the video file's compressed data, which causes the video to display unexpected visual artifacts and glitches. The effect is often used to create a sense of motion or to add an element of abstraction or surrealism to a video.
In video compression, there are 2 types of frames:
The method of Datamoshing I'll be using is I frame Datamoshing which deletes an i frame from an mp4 file, causing the p frames to overwrite certain frames in the video with the data from other frames.
Though similar to Databending, Datamoshing is a result of glitchy compression whereas Databending is a result of the data itself being altered.
The tutorial above is slightly outdated so here's some amemdments for it to work on the newest version of avidemux.
Here's a video of me trying datamoshing:
