How do I upload movies for free to my website for watching movies and TV shows?


So, I want to make my own website for watching movies and TV shows but not in English but in my native language. So I was wondering is it legal to just upload videos from the openload server or some other server to my website without having to pay for an openload account or something or does openload just let me upload their videos for free. It might be a stupid question but I am really not familiar with this subject and if you have any tips for building my movie watching website what would be great. Thanks!!!
