You Tube, it has a bunch of video clips from all over the world and of subjects matter from everything u can think of.  there's a no nudity rule. but there are clips that push it tho. but the MISORA HIBARI clips, if u see it now it may not be there in a few weeks - copyright violations get removed, they are pretty active deleting stuff too. 

u can also find historically significant films and archival footage there too.
