How are short films made? What are their sources of funding?

Short films are made by a number of different individuals and companies. For example short films are made for ambitious and up and coming directors who want to make a name for themselves in the industry; so for these individuals the source of funding comes from their own pockets and they fund themselves. Another way these types of people make films and recieve funding is by going onto websites such as http://www.bbc.co.uk/filmnetwork/filmmaking/guide/before-you-start/funding#sources  to get donations and tips on ways to get funding for the short film.

Another source of funding for short films is companies who hire short film crews to create a promotional video for their product. A prime example of this is the use of live action video's for video games, the franchise 'Call of Duty' hired a film crew to create a promotional piece for their upcoming game, also using film stars to add more appeal. http://www.youtube.com/watch?v=zuzaxlddWbk
