You raise an important issue. Copyrights can be tough but keep in mind this is international, not US. What works in one country might not in others. If you're talking about you having a copyright on your material, don't expect a lot of privacy when you go online. Some countries don't recognize copyrights from other countries so it is something you have to work around.
I've found that for business videos (the world where I live) it is best to assume your content will be copied and design it accordingly.
Thank you for your comment. Nice to have you stop by.
