AE Scripts previewed a new plug-in for After Effects called Data Glitch:
"... it creates awesome realistic digital image glitches with total ease. Something you would see during a satellite transmission or a cable broadcast or from a damaged disk. Bad TV plugin is great for analog TV look, but this is 2010 and you hardly see anything that’s analog anymore. This plugin simulates a realistic digital glitch effect.In real-life most of the glitches occur due to problems in encoding/decoding and sometimes data corruption. This plugin does exactly that. It encodes the data, glitches the data and then decodes it similar to the real life situation."
Plug-in author Satya Meka has additional details at his website. In a Twitter message @aescripts said that "Data Glitch is completely expressionable. I created the demo in about 15mins by tying all the params to the audio:"
Update: another from Satya...
