DISCLAIMER:
I'm just a student doing what I enjoy the most which is editing videos.
Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research. Fair use is a use permitted by copyright statute that might otherwise be infringing."

The materials are used for illustrative and exemplification reasons, also quoting in order to recombine elements to make a new work. The original works were altered quantitatively or qualitatively and the video does not compete with the market for the original works. There were used small portions of the materials in a new context and expression for illustrative reasons only.

I do NOT own the video materials and all credits belong righteous owners. In case of copyrights issues before taking action, please contact me immediately.
