Trailer mashups also known as recut trailers, involve collecting multiple pieces of film footage from one or multiple movies and editing them to create a new trailer. Trailer mashups are often created for a movie that does not exist or to change the genre of an existing film. Trailer mashups existence and popularity can be credited to convergence culture and the Web 2.0 infrastructure, allowing films to be easily accessed and shared online on video sharing websites such as YouTube.
This channel conceptualizes a specific non existing film, it contains clips from existing productions to make with creativity and a lot of effort, a new vision of that idea. This is called a CONCEPT TRAILER. No copyright infringement intended. I don't own the material; I only make trailers for the fans and the people who are hyped for a movie.
