![]() ![]() An example of datamoshing when the i-frames of a video are removed. It almost looks as if the pixels have been projection-mapped or tracked onto the next shot. This typically results in pixels from a previous scene getting projected onto the next scene. The first is if the video’s i-frames get removed. There are two distinct pixel effects this can create (or sometimes a mix between the two). ![]() You also may have seen it occur while watching satellite TV during a thunderstorm, where there may be some interference with the video signal.Īs mentioned earlier, when errors occur with a compressed video’s i-frames or d-frames, datamoshing is the result. The first time I saw the effect (the unintentional version), I was watching a video on a handheld digital-TV receiver. Historically, this would be an undesirable visual effect because it obviously means an error has occurred with the video compression or video signal. ![]() Historically, datamoshing was an undesirable effect, caused by errors with video compression. This results in what we call the datamoshing effect. However, if the d-frames become corrupted, or if the i-frames get removed, the pixels onscreen will move in some extremely glitchy ways. The d-frames are much more efficient for video compression since they store only pixel movement data rather than an entire image. I-frames are essentially a complete image of a video frame, whereas d-frames are comprised of where pixels from an i-frame need to move to. Compressed videos contain i-frames and d-frames. In short, datamoshing messes with a video’s compression, causing the pixel information to become corrupt. ![]()
