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. ℹ️About GitHub Wiki SEE, a search engine enabler for GitHub WikisĪs GitHub blocks most GitHub Wikis from search engines.In short, datamoshing messes with a video’s compression, causing the pixel information to become corrupt. Thats all with FFglitch, you can even do lots of experiment with this alone. This is one comparison video you can watch: This is useful if you want to remove artifacts from the video (specially the green portions). A less value means less glitches, 1000 means a longer glitch. The two main settings of FFglitch modes are: Keyframes (Glitch Size) Just write the frames in the box and it will do the operations automatically. This is another powerful custom effect where you can spam or delete frames easily. You may need to learn javascript or python to understand the scripts. This is where you can experiment with your own scripts inside of datamosher-pro, the fluid and stretch mode in script format is given by default for reference. Some results I created with these effects: You can find more scripts here: DD_Glitch Assist Many other preset type effect like buffer, delay, invert-reverse, zoom, slice are normal script effects taken from Glitch Assist (An application that uses ffglitch). This effect is similar to bloom but gives more detailed results at any frame. Doesn't work that good but still glitchy. This effect takes the vector information from a secondary video file and applies it in top of the main video. Like here in the same car video where I deleted the frames from 90 to 120, What it does is simply remove the i frames. The Rise mode is more manual and lets you apply the shuffle transition only at one part. This is just simple motion vector operation.īoth are same but shuffle just randomly shuffles the parts of video(chunks of frames) and moshes them together. This mode plays with the average motion vector of a video. It generally plays with the motion vectors of the video, I don't want to go deep in this but you can do your own research on Basic Pack (taken from the ffglitch main page): Fluid Here comes one of the best tool for datamoshing and also for glitch art purposes.
