IMDb title and credits creation for short film

Hi, 

two of my short films were part of Oscar qualifying film festivals. The second one won also an award at an IMDb qualifying festival. 

Is it possible to create titles for those short films on IMDb and get a directing and animaion credit or will it be denied? I´ve read that I need "suitable evidence" - is such a proof also a link to one of those festivals that shows my short film in their program?

Best
