7 rules about short films

Ater reading the article "7 rules for writing short films" ive learned that if your making ahort film it should only last from 15 seconds to 45 mnutes and if you're putting it into a festival it should be no longer than 10 minutes. i have also learned that certin scenes for example like car accidents or explosions take alot more time to shoot rather than you shooing someone walking and getting into a fight unless your an expert at shooting shorts and CGI and lastly ive learned that when making a short films its important not to have too much dialouge. I liked the way the article was set up starting from rule 1 and so on. i also liked the information it gave me about short films. What will the next best short film be?
