Datamoshing just involves 'painting' the wrong image onto the motion. Put another way, the effect of video compressors that use this technique is 'painting' the state of the movie at one point in time onto the actual motion of the image for several frames, in a way that is mostly imperceptible.
Datamoshing involves deleting certain frames, or otherwise messing with their order, so that P- and B-frames reference the wrong I-frames, and such. Encoding chunks of an image like this can be much, much smaller that encoding the full image data. The idea of P- and B-frames is that often, small chunks of a video do not change from frame to frame, or can be approximated very closely as just a small amount of motion of a chunk form the previous frame. 15 Up to 15 minutes of footage provided Up to 2 minutes running time Color grading Sound design & mixing Motion graphics Subtitles. Frames that are coded in reference to other frames look at the motion vector displacements for small chunks of the frame ( macroblocks, &c.). In digital video compression, some frames are coded only with reference to themselves ( 'I-frames' or 'key frames,' &c.) and some frames are coded with reference to other frames ( 'P-frames' and 'B-frames').
The important thing to understand about datamoshing is that it leverages a technique that is common to many digital video compression algorithms. Learn how to Datamosh all by yourself All it takes is a couple programs, a couple hours, and a couple tabs of acid.
