Youtube is where you SHARE your videos, not making. You could upload your movie to dailymotion/vimeo and more.
I suggest to start with the basic, based on what you said, you DON'T know how to make videos. Get a free high quality screen recorder (If you want the movie to happen on the SM app/website and your friends roleplay) and a good video editor (If you want to hook the audience with special effect).
High quality and plot are important when you want to make a movie, if you can't speak English, just do it in Indonesian and add the English subtitle.
