Film editors can be broken down into several groups. There are the main editors that put together every scene of a film, assistant editors who will help out with the process, and special editors who may work on special effects, animations or titles for movies. Film editors are also involved with process of trailer and promotion material when a movie is released. There are many high-paying jobs in this field; just look at a list of movie credits and you can see the wide ranges of editors needed on a film.
Like film, television editors are needed to compile episodes, promos and previews for upcoming weeks. In many cases this can have a bigger workload than the film editor because there are so many episodes created every season. Commercials are another big part of television, and editors are needed to create every commercial seen in between the shows.
News editors are a lot different then editors for other television programming. News editors must work in a fast-paced environment and edit together multiple news packages everyday. Live editors are also needed to cut and create the live broadcasts much like sport's broadcasts or any other live programming.
The expansion of high-speed Internet has created the need for video editors. Editors can compile original footage for websites like youtube, or work for online editions of popular news websites like CNN. Video editors are also needed for the expanding base of online programming and Internet-only shows.
Instead of going out and finding an editing job, you work at your home. Running a self-employed editing business will allow you to choose the jobs you want and to edit in the the luxury of your home with your own equipment. You can offer big production services, smaller services, or a mix of both. News that you provide consumers with pro editing skills will spread by word of mouth, and soon you could have a large and profitable customer base.
