A step-by-step tutorial on datamoshing, demonstrating how to create glitch art by removing keyframes from compressed video files.
Learn how to Datamosh all by yourself! All it takes is a couple programs, a couple hours, and a couple tabs of acid.
UPDATE: The one-stop datamosh kit is outdated. Sorry, it's been over six years, and computers be changin.
You can still download ffmpegx on your own, but you'll still need to download the "binaries" for it too. It'll show you where to grab the binaries from when you open ffmpegx.
OR you can use another file conversion program, like MPEGStreamclip, or even Adobe Media Encoder/Premiere/After Effects. In fact, they're a bit easier to use than ffmpegx (and no pesky binaries)
NOTE TO PC USERS: Instead of FFmpegX, you can use VirtualDub (virtualdub.org). I've never used it, but I hear it's the bee's knees!
Now, for avidemux, you're going to need version 2.5.4 (none of the newer versions worked for me):
sourceforge.net/projects/avidemux/files/avidemux/2.5.4/avide…
Unfortunately if you try to open the program it won't open. But there's a fix! (This has been tested on OS X 10.10 Yosemite and below).
After you've copied avidemux into your Applications folder, right-click on it and choose "Show Package Contents." Then open up "Contents" then "Resources" then "lib"
In the "lib" folder, find and delete two files: "libxml.2.dylib" and "libiconv.2.dylib". Don't worry, this won't harm anything on your computer, it will just make avidemux work like it's supposed to.
And voila! Everything else should work like in the videos. Hope this helps!

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: link to 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: linklink
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: link to this video

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. linklinklinklink to this video
