Credit should go to landru79, he keeps finding interesting things in Rosetta's raw data. I basically just tried to correct for Twitter's terrible video handling by re-tracing his steps :)

Go check landru79's Twitter feed, there are many more interesting comet images and videos (e.g. he combines multiple frames into color images):

BTW here are original ESA images:
