If u have interest, how do u go about learning the basics and finally reaching your dream?
You must go abroad and go to a Arts school. If not, you become an actor and learn from there.
No it's not necessary to go to an Art school or film school or have any degree or any other paper qualification. Talent, luck, and opportunity are all you need really.
You need connections to the media industry. Seriously. Then just ask whether you can tag along for, lets say, a video production. Small scale large scale doesn't matter. It'll be good if you have video editing or photography skills as well since video directors work with the video editors most of the time and camera angles can acquire from photography...
Most importantly, watch more good videos.
I heard of dozens who have no paper qualifications in Media and arts but become successful movie diectors. I wonder how.
