A short film is a film with a low running time. The Academy of Motion Picture Arts and Sciences defines a short film as "an original motion picture that has a running time of not more than 40 minutes including all credits".[1] Other film organizations may use different definitions, however; the Academy of Canadian Cinema and Television, for example, currently defines a short film as 45 minutes or less in the case of documentaries, and 59 minutes or less in the case of scripted narrative films.[2]
In the United States, short films were generally termed short subjects from the 1920s into the 1970s when confined to two 35 mm reels or less, and featurettes for a film of three or four reels. "Short" was an abbreviation for either term.
The increasingly rare industry term "short subject" carries more of an assumption that the film is shown as part of a presentation along with a feature film. Short films are often screened at local, national, or international film festivals and made by independent filmmakers with either a low budget or no budget at all. They are usually funded by one or more film grants, nonprofit organizations, sponsors, or personal funds. Short films are generally used for industry experience and as a platform to showcase talent to secure funding for future projects from private investors, a production company, or film studios. They can also be released with feature films, and can also be included as bonus features on some home video releases.
