A lot of these clips can be found online and OP can probably even argue a case for the clips themselves as fair use. I'd say it's more of a problem with copyright of the song than the anime clips.

Just because OP has all of these clips doesn't mean they stole all the anime. I could download this video, isolate the clips I want, add a new track, and give you a new video if I wanted. And I don't own any of the anime. Not saying they didn't either, but it's not impossible to do this kind of stuff without having the material.
