Copyright does not have to be labeled. Because many video clips are for entertainment, not for commercial purposes, they are all for self-entertainment, so it is ok to label them or not, but if they are for commercial purposes, they need to be labeled, not only for labeling, but also for payment. Copyright is copyright, which refers to the rights (including property rights and personal rights) enjoyed by authors of literary, artistic and scientific works. Copyright is a kind of intellectual property, including natural science, social science, literature, music, drama, painting, sculpture, photography and film works.
