Datamoshing is a form of glitch art which occurs when ‘the I-frames or key-frames of a temporally compressed video are removed, causing frames from different video sequences to bleed together‘.
P-frame duplication in avidemux 2.5.4 on Mac OS X image I had thought it wasn't possible to install a version of avidemux that was old enough to use for datamoshing on Mac OS X. It turns out that that's wrong, and avidemux 2.5.4 works just as well as 2.5.6 for datamoshing on Mac OS X! A.dmg was never distributed for 2.5.6, but one was distributed for 2.5.4 and it's easy to get working on.

HOW TO DATAMOSH (See also: PART 2: ENTER THE P-FRAME and PART 3: THE DATAMOSH ACTUALLY HAPPENS)
They guy behind these videos seems to have popularised the technique with a Chairlift music video for Evident Utensil, but Sony would rather you didn’t see it.
(Shh, it’s on Metacafe.)
AviGlitch is a Ruby library claims to be the easiest way to datamosh a video file. (In this case, ‘easy’ seems to assume you understand the first thing about Ruby.)
Datamoshing videos can be a time-consuming process, automation can help. For Windows users AutoHotkey is free, open-source macro-creation and automation software that can handle some of the repetitive tasks involved in datamoshing.
The following script for AutoHotkey automates I-frame removal in Avidemux, normally a manual process described in this tutorial. The video above was datamoshed using this automation script.
Load AutoHotkey with the script below and then when it comes time to remove I-frames in Avidemux simply focus the slider below the video and press Control+F to trigger the AutoHotkey script. The script will send the appropriate key strokes to remove the next 10 I-frames while you pop out for a break.
These types of scripts could also be used to automate key strokes while hex editing images, consider a script which would move a certain number of characters across and then insert a character — that could glitch out an image quite nicely. Similarly one could experiment with automating photo editing processes by scripting with a program like AutoHotkey.
Some of these types of automation could be accomplished through the usage of a programming framework, or scripting language, but automating at the user interface level can remove a lot of overhead and restrictions.
