Another method I have used in the past is to go straight to the source instead of trying to emulate.
Encode your clip in question to various compressed formats (mjpeg, h264, etc), open those compressed files in a hex editor, and randomly experiment with find/replacing random strings of hex digits until you find something that looks cool, and then transcode it back to a non-corrupt data stream. This is sometimes referred to as "databending". "Data moshing" is basically manipulating compressed video by removing i-frames so that the motion estimation b frames continue to move macroblocks but have no image data to move and get corrupted. More sophisticated methods of "emulation" may be effective as well, though you have to be pretty smart. (Custom image processing code, using motion estimation techniques, or output of 3d software simulations) Here are some links that may be of interest: https://dl.dropboxusercontent.com/u/9054743/lofi%20Rosa%20Menkman%20-%20A%20Vernacular%20of%20File%20Formats.pdf https://vimeo.com/86204390 http://onoffar2.free.fr/HTML/divxp.htm https://launchpad.net/datamosher On Fri, Jul 10, 2015 at 11:44 AM, Peter Sidoriak <pe...@petersid.com> wrote: > We tried this on a Music Video I worked on.
