A Video Editor is involved in video production and the post-production of film making. Video Editors usually use non-linear editing software to accomplish the task of editing. A Video Editor is a technically inclined individual that makes creative video editing decisions.
Video Editing is the process of manipulating and rearranging video shots to create new work. Video Editing is usually considered to be one part of the post-production process — other post-production tasks include titling, colour correction, sound mixing, etc.
As a Film or Video Editor, you'll be responsible for assembling recorded raw material into a finished product that's suitable for broadcasting. The material may include camera footage, dialogue, sound effects, graphics and special effects.
The difference between Film and Video editors is the technology they use to edit their work. Film Editors may physically tape and splice scenes together through a lightbox. The process of a Video Editor is still tedious and time-consuming, it is a much more seamless process than analog film editing.
