Part 1 of a how-to on datamoshing, the video glitch effect made by manipulating compressed video, for example by removing keyframes so that motion smears across frames.

HN people share it as the how-to for the datamosh effect, alongside the music videos and glitch art that made it popular.

Thank you very much! I'll try and see if I can get my hands on a projector again. Generative art != glitch art, but these might be of interest to some people as well, since there was thread about a week ago on PNG glitching, and I went down a rabbithole saving links. link link link ▶ this video

Because it's beautiful. The effect is known as datamoshing and has become popular in some contemporary video art. It got popular from a Chairlift music video and is achieved by removing keyframes from compressed videos. Check out this how-to for the non-Ruby way to do it: ▶ this video Here's the Chairlift video: link And here's some work (from Takeshi Murata) that I think directly influenced the datamoshing effect becoming popular: link link

Whoa, cool. Reminds me a bit of a video codec technique to exaggerate the motion frames and compression ala "datamoshing". Keyframes are removed which leaves only information from the previous frame to be updated by motion frames. Than update/motion frames are reiterated sequentially which creates an effect that just further saturates the previous frame and looks like a fluid melting effect. in use: link how to via ffpmeg: ▶ this video
