TITLES: OPENING CREDITS

TITLES

OPENING CREDITS 
After researching the rules created by guild rules and other unions I realised that there are specific rules involving the order of the credits. Generally this is the order of the title sequence 

PRODUCTION COMPANY presents a NAME LASTNAME production a NAME LASTNAME film "TITLE" Lead Cast Supporting Cast Casting Director Music Composer Costume Designer Associate Producers Editor(s) Production Designer Director of Photography Executive Producer Producer Writer(s) Director 

If the writer and director are the same person, or the director was also a producer, hold his earlier credit and pair it with the more prestigious one (in this case "director"). so you would place "Written and Directed by" or "Produced and Directed by" or "Edited and Directed by" where the Director's credit goes. if your Dp was also your editor, you'd have "Editor and Director of Photography..." falling in the position where the DP credit goes. et cetera. 
CLOSING CREDITS Closing credits do not have any hard and fast rules that dictate how they need to be ordered. But there are conventions that have been established. If you intend to have no opening credits (something George Lucas left the DGA over) you basically put the Director, Writer and Producer credits first, then go down the line for the closing credits: 

Director Writer(s) Producer Executive Producer Lead Cast Supporting Cast Director of Photography Production Designer Editor(s) Associate Producers Costume Designer Music Composer Casting Director

PRODUCTION LOGO if you have an Animated Production Company Logo, place that at the very beginning, before your credits. it's the first thing we see. some studios/production companies will tag the logo on at the very end too. 
BREVITY Now, it's important to note that on a short film, many of the roles you see above were handled by one person. I've been to a few film festivals and there is nothing more likely to induce a collective groan, and lose a few fans in the process, than a tedious string of credits on a five minute film... especially if the same names keep popping up. and I'll tell you why. at festivals, shorts are programmed in blocks of 90 to 120 minutes. no one in the audience cares who did what. so waiting thru two minutes of white test scrolling against black is pretty miserable for everyone. it also does a disservice to your fellow filmmaker. shorts blocks thrive on momentum. I've seen people leave the theater over because of long credits. in particular, I sat through a 22 minute film followed by 6 minutes of very detailed credits. HALF the theater left before my film screened. half. 
The best advice I can give here is that if you were the writer, director, producer, cinematographer and editer... just go with the most important titles (in this case... "written and directed by...", dropping any credit for your editing or cinematography. Or maybe "a film by..." is enough. Didn't have a casting director and held scheduled the auditions yourself? skip it. And even if you had a crew of 20-30 people, move through those credits as quickly as possible.
