リニア編集（リニアへんしゅう）は、ビデオカメラで録画されたりスタジオ収録されたりしたビデオテープに記録された画像と音を選択し、整えて、修正する過程である。1990年代はじめにコンピュータによるノンリニア編集が登場するまでは、リニア編集は単に「ビデオ編集」と呼ばれていた。 ==沿革== ===編集前史=== ビデオテープの導入までの間、テレビは基本的に生のメディアであった。 The function of shot edits, were, in live television production, performed by switching from among two or more cameras. This was (and is) accomplished using a video switcher, an electronic device capable of handling two or more synchronized video inputs and combining them into a video output. A switcher can be used to perform cuts between video sources, or any number of longer transitions, such as wipes, fades and dissolves, with multiple sources. Actual live television is still basically produced in the same manner as it was in the 1950s (although transformed by myriad technical advances). However, the only way of airing the same shows again (and again...) before videotape was introduced was by filming shows using a kinoscope (essentially, a video monitor paired with a movie camera). However, kinoscopes (the films of television shows) suffered from various sorts of picture degradation, from image distortion and apparent scan lines to artifacts in contrast and loss of detail. Also, kinoscopes had to be processed and printed in a film laboratory, making them somewhat dicey for broadcasts delayed for different time zones. So, the primary motivation for the development of videotape was as a short- or long-term archival medium. Only after a series of technical advances spanning decades did videotape editing finally become a viable production tool on a par with film editing. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「リニア編集」の詳細全文を読む スポンサード リンク
