Finland in timelapse by Riku Karjalainen

:D As long as the cut is not on the beat, it is are governed only by the video content and its own rules – and there are gazillions of those! My old professor was a former film editor and he made it clear to his students – even though we were not studying editing – how demanding a profession it is. And he was right, too! We are all just so used to watching well edited moving image that we don't even notice it's been assembled from bits and pieces – let alone how.

And yet it was only 100+ years ago when some film pioneer realized to his surprise that if you show a farmer fixing his eyes at something, then cut to a horse, the viewer thinks he is looking at the horse. Today everyone takes it for granted.
