To remove these frames we can hit delete on the keyboard, or Edit->Delete from the menu. Now we have a selection of the frames we want to remove, this selection can be seen as a blue rectangle on the timeline. Then to end the selection we press the ending point button (Button with a “B”). Then we advance to the next frame that is not a key frame using these buttons. To select our key frames, start at an I-frame and start the selection by clicking the starting point button (Button with an “A”). Sometimes you may have two consecutive I-frames/key frames. To skip through key frames we can use these buttons. Next we open our first converted video, scrub through and remove all key frames except the first frame. Repeat this process for the second video. This is now a compressed compatible video where we minimized the amount of I-frames/ key frames. Now save the file using File->Save from the menu. * If you are using version 2.5.X instead change the “maximum I-Frame” interval, under the frame tab, to a large value (or as many frames your video contains). Change the number of “B-Frames” to 0, and “GOP Size” to 500. From the video output drop-down, select the Xvid codec.Ĭlick configure to adjust settings.

Open the first video in AVIDemux using File->Open from the menu.

During this process we will also want to minimize the number of key frames in our converted video. You will also need two compatible videos of the same resolution to “mosh” together.įirst we want to compress the videos as an AVI using the Xvid codec. However, 2.6.X works fine for the basic datamoshing technique and is the only version I have found that works for recent versions of OSX. It is recommended to use version 2.5.X as this version allows for easier frame cut and paste operations.

AVIDemux is a free program that allows for video compression as well as frame by frame editing. To use this technique, you need a way to manipulate these frames. This post is an effort to guide through and simplify the process of datamoshing using free tools. The technique of datamoshing involves removing key frames and manipulating transition frames to achieve a unique glitch aesthetic. These frames contain information that has changed from the previous frame and are used to construct the next frame. Then we have the in between frames, also referred to as p-frames. These frames contain mostly new information, or information that cannot be compressed. Key frames, or I-frames, are frames that usually occur in the beginning of a new scene. Compressed video is made up of several kinds of frames. Datamoshing is a technique that manipulates the frames in a compressed video.
