Editor

An editor is responsible for assembling raw material into a finished product suitable for broadcasting. The material they work with may consist of raw camera footage, dialogue, sound effects, graphics and special effects. This is a key role in the post-production process and the editor's skill can determine the quality and delivery of the final product. The editor may be part of a team and they will usually work closely with the director to achieve the desired end result. 
I will also have to work closely with the Cinematographer during the planning stages to make sure the shots are the right length so that the audience do not get bored. My job will begin as soon as the filming begins as I will have to make sure the director's vision can work as a film and will look good. 
In a horror film, the music has to be perfectly time otherwise it has no effect and also the shot types must be interesting e.g high angles, it will be my job to make sure both of these happen. It is important because if my job is not done properly, our horror film will look very unconvincing and the quality of the film will be compromised, I will also have to make sure the continuity is right. Editing has to be done perfectly otherwise the narrative of the film may not make sense and the themes can be changed.
