The video editor must make changes to scenes that don’t take away from the director’s vision, but that also help keep the viewer’s attention. Cuts made cannot detract from the story or confuse the audience by taking away scenes with critical information needed to understand the action.
The video editor must ensure that the final length of the film is reasonable, and in context with the genre and anticipated audience attention span. Cuts may be made on an autonomous basis, depending on the director's preferred level of involvement in the video editing process. In some cases, where great disparity exists between the director's vision and the video editor's decisions, a separate "director's cut" is made. The director's cut is the version that represents how the director would have edited the film.
Angles & POVs
The video editor may make decisions about which angles and points of view are used in scenes. The director will often shoot scenes from different angles so the video editor has a selection from which to choose.
In post-production, the video editor may incorporate CGI or other enhancement effects into the film in order to achieve a certain look or emphasis. Lighting, sound and other special effects may by utilized in collaboration with film engineers.
