Linear video editing
Résumé
Linear video editing is a video editing post-production process of selecting, arranging and modifying images and sound in a predetermined, ordered sequence. Regardless of whether it was captured by a video camera, tapeless camcorder, or recorded in a television studio on a video tape recorder (VTR) the content must be accessed sequentially.
For the most part video editing software has replaced linear editing. In the past, film editing was done in linear fashion, where film reels were literally cut into long strips divided by takes and scenes, and then glued or taped back together to create a logical sequence of film. Linear video editing is more time consuming and highly specialised and tedious work. Still, it is relevant today because of these reasons:
The method is simple and inexpensive.
Mandatory for some jobs: for example if only two sections of video clips are to be joined together in sequence it is often the quickest and easiest way.
If video editors learn linear editing skills it increases their knowledge as well as versatility. According to many professional editors who learn linear editing skills first they tend to become proficient all-round editors.
Until the advent of computer-based random access non-linear editing systems (NLE) in the early 1990s, linear video editing was simply called video editing.
Live television is still essentially produced in the same manner as it was in the 1950s, although transformed by modern technical advances. Before videotape, the only way of airing the same shows again was by filming shows using a kinescope, essentially a video monitor paired with a movie camera. However, kinescopes (the films of television shows) suffered from various sorts of picture degradation, from and apparent scan lines to artifacts in contrast and loss of detail. Kinescopes had to be processed and printed in a film laboratory, making them unreliable for broadcasts delayed for different time zones.
The primary motivation for the development of video tape was as a short or long-term archival medium.
