@dramas _ nocturnal how should one learn script/screenwriting? Is learning from Youtube good enough?
Based on my experience, learning from YouTube can't compare to real learning. I would recommend a seminar or short course, either online or in class. That way, you will learn more about how to develop the story and concept - plots, subplots, characters and characteristics, conflict, climax, and resolution. I believe that a good-quality script is more than just a story; it is how impactful the story can deliver. When you write a script, you don't have think much about the direction because there's a director to do that part.

I have some experience in videography, cinematography, video editing and should I say direction? In that way , I have written scripts as a form of ideating my videos.
It's good that you have the knowledge of the technical parts (the production and post production), so maybe you can really create something.
