This is 'datamoshing'

i use pretty severe mp4 compression for the movies i keep on my computer, and when the processor gets taxed by some other app, this often happens momentarily to the playback.  i enjoy it every time.

le_sacre, RIGHT. That is the "technique". Sometimes I see it on cable or satellite TV for the exact same reason... always thought it was trippy... guess someone figured out how to make it happen on purpose...

I love how when the image pixelates and the other motion takes over, it's like, yes painted, with those pixels, until the processing catches up.

Who says there's not wonder in digital accidents?
