Not sure if many people know about Vimeo.com; it’s a relatively recent video website. The users are few, but most of the works are original, in that they are made by the users themselves, mostly as independent film-making or photographic experiments like ‘timelaps’. Definitely higher in quality than YouTube and the likes.
There is also an HD section which offers high resolution videos.
Give it a look if you haven’t already. It’s so navigation-friendly.
