A scene that took two days to shoot plays for four minutes in the first assembly. Nobody laughs at the joke in the middle. The editor tries it with a shorter pause, then from a different angle, then cuts the joke entirely and moves a reaction shot forward. Now the scene works in ninety seconds. The editor is the person who turns hours of footage into the film the audience actually sees.
What an editor does
The editor works closely with the director and, later, with the producer. Work usually starts on the first day of the shoot. Footage arrives every day, the editor watches it (these are the dailies, or rushes) and assembles scenes in script order. This lets the team spot missing shots while the set and actors are still available.
After the shoot comes the editor's cut, then the director's cut, then rounds of notes from producers, financiers and sometimes a broadcaster or distributor. Test screenings can lead to more changes. The editor's work ends at picture lock, the moment the timing of every shot is final. After that, sound, music, colour and visual effects are finished against that locked version in post-production.
Responsibilities
- Watch the dailies and assemble scenes during the shoot
- Flag missing coverage or problems to the director while the shoot is running
- Shape the structure, pace and performances of the film across several cuts
- Work through notes from the director, producers and financiers
- Prepare cuts for screenings and test audiences
- Lay in temporary music and sound so the cut can be judged properly
- Hand over a locked picture with clean lists for the sound, colour and VFX teams
How the role touches the budget
Indirectly, but more than people think. The editor's own costs are mainly their weekly fee, the assistant editor and the cutting room with its editing systems. The bigger effect is time. Every extra week before picture lock means more weeks of cutting room rental and crew, and it pushes back every booking that follows. A cut that needs extra shoot days or new visual effects shots also lands on the budget, so the post-production supervisor keeps a close eye on the edit schedule.
How people become editors
The usual route is through the cutting room. People start as runners at a post house, become assistant editors and spend years learning both the software and how experienced editors think. Many cut short films, music videos or documentaries alongside that to build a reel. Some editors move up through TV, where the volume of work is higher.
In TV and commercials
In TV, editors often cut several episodes of a series, with different editors on different episodes and a strict delivery date per episode. Documentary editors build the story largely in the edit, from much more footage than a scripted drama. In commercials the editor often works at a separate edit house and cuts in days rather than months, with the agency and client in the room.
