What kind of movies are film school applications looking for?
I recently applied to National Film and Television School (NFTS) UK and got rejected. What exactly are film schools looking for in their applications? Especially for whatever the equivalent of a graduate course for aspiring directors is in top film schools like American Film Institute (AFI), NYU Tisch, USC CA, UCLA, etc.? I'm specifically talking about their creative portfolio requirements, when they ask to submit short films you've worked on (or directed in this case as I'm an aspiring director).
Skill: are they looking for more professional and polished work or are they fine with amateurs and beginners? Especially in graduate courses as I've already finished an undergraduate course in something else and I think a graduate course would be better.
Budget: I'm sure they'd be fine with low budget productions but I'm just adding this as a box to be ticked.
Story: any particular kind of story or genre they're looking for in your experience?
Characters: Same as story.
Others: Any other advice you can think of on how to improve my application. Please be as detailed as you can.
Sorry if my questions seem stupid but I'm a huuuuge beginner so please cut me some slack. I really want to attach my work that I sent as part of my application but I feel that adding a flair tag as asked to by the rules would put people off from interacting with the post as they'd rightfully not want to watch some amateur's fumbling. I'll make a separate post with my work linked so people can critique it there if they wish.
If anyone has any work that has helped them or others get accepted to top film schools or even a good one, please link it in the comments so I can watch and learn.
