You don't file a dmca takedown against a video, you file against a URL. All you're claiming is that your copyrighted content is somewhere in that url. But even if you were filing against a video directly, it doesn't mean you're claiming ownership of the video. It could just be one song on the soundtrack, Or a still photo shown without authorization, Or one of the actor's tattoos (seriously) that is the subject of your claim.
