Filmmaking (or, in an academic context, film production) is the process of making a film, generally in the sense of films intended for extensive theatrical exhibition. Filmmaking involves a number of discrete stages including an initial story, idea, or commission, through screenwriting, casting, shooting, sound recording and pre-production, editing, and screening the finished product before an audience that may result in a film release and exhibition. Filmmaking takes place in many places around the world in a range of economic, social, and political contexts, and using a variety of technologies and cinematic techniques. Filmmaking also takes place outside of the mainstream and is commonly called independent filmmaking. Since the introduction of DV technology, the means of production have become more democratized and economically viable. Filmmakers can conceivably shoot and edit a film, create and edit the sound and music, and mix the final cut on a home computer. However, while the means of production may be democratized, financing, traditional distribution, and marketing remain difficult to accomplish outside the traditional system. In the past, most independent filmmakers have relied on film festivals (such as Sundance, Venice, Cannes, and Toronto film festivals) to get their films noticed and sold for distribution and production. However, the Internet has allowed for the relatively inexpensive distribution of independent films on websites such as YouTube. As a result, several companies have emerged to assist filmmakers in getting independent movies seen and sold via mainstream internet marketplaces, often adjacent to popular Hollywood titles. With internet movie distribution, independent filmmakers who choose to forgo a traditional distribution deal now have the ability to reach global audiences.
