The term video editing can refer to:
Background
Video editing is the process of editing segments of motion video production footage, special effects and sound recordings in the post-production process. Motion picture film editing is a predecessor to video editing and, in several ways, video editing simulates motion picture film editing, in theory and the use of linear video editing and video editing software on non-linear editing systems (NLE). Using video, a director can communicate non-fictional and fictional events. The goals of editing is to manipulate these events to bring the communication closer to the original goal or target. It is a visual art.
Early video tape recorders (VTR) were so expensive, and the quality degradation caused by copying was so great, that 2 inch Quadruplex videotape was edited by visualizing the recorded track with ferrofluid and cutting with a razor blade or guillotine cutter and splicing with video tape. The two pieces of tape to be joined were painted with a solution of extremely fine iron filings suspended in carbon tetrachloride, a toxic and carcinogenic compound. This "developed" the magnetic tracks, making them visible when viewed through a microscope so that they could be aligned in a splicer designed for this task.
Improvements in quality and economy, and the invention of the flying erase-head, allowed new video and audio material to be recorded over the material already recorded on an existing magnetic tape and was introduced into the linear editing technique. If a scene closer to the beginning of the video tape needed to be changed in length, all later scenes would need to be recorded onto the video tape again in sequence. In addition, sources could be played back simultaneously through a vision mixer (video switcher) to create more complex transitions between scenes.
Editor in linear VCR suite
There was a transitional analog period using multiple source videocassette recorder (VCR)s with the EditDroid using LaserDisc players, but modern NLE systems edit video digitally captured onto a hard drive from an analog video or digital video source. Content is ingested and recorded natively with the appropriate codec which will be used by video editing software such as Sony Vegas, CyberLink PowerDirector, Avid Technology's Media Composer and Xpress Pro, Apple's Final Cut Pro (FCP), Adobe Systems's Premiere, and EditShare's Lightworks to manipulate the captured footage. High-definition video is becoming more popular and can be readily edited using the same video editing software along with related motion graphics programs. Video clips are arranged on a timeline, music tracks, titles, digital on-screen graphics are added, special effects can be created, and the finished program is "rendered" into a finished video. The video may then be distributed in a variety of ways including DVD, web streaming, QuickTime Movies, iPod, CD-ROM, or video tape.
Home video editing
Like many other technologies, the cost of video editing has declined by an order of magnitude or more. The 2" Quadraplex system cost so much that many television production facilities could only afford a single unit and editing was a highly involved process requiring special training. In contrast, nearly any home computer sold since the year 2000 has the speed and storage capacity to digitize and edit standard-definition television (SDTV). The two major retail operating systems include basic video editing software - Apple's iMovie and Microsoft's Windows Movie Maker.
There are also more advanced commercial products such as AVS Video Editor, Adobe Premiere Elements, AVID Express DV, CyberLink PowerDirector, Final Cut Pro X, Sony Vegas, Pinnacle Studio, Ulead VideoStudio, Roxio Easy Media Creator, muvee autoProducer, and Videopad.
Additionally, there are free, opensource video-editing programs. These include Avidemux, VirtualDub, Kdenlive, PiTiVi, Kino, Openshot and Cinelerra. A new free and collaborative video editing platform called WeVideo was introduced to the market in September 2011, which allows multiple users and editors for a unified video real.
Automatic video editing products have also emerged, opening up video editing to a broader commercial audience of amateurs and reducing the time it takes to edit videos. Muvee Technologies introduced their PC-based automatic video editing platform, autoProducer, in 2001. Other early solutions included Sony’s MovieShaker, which released its final version in 2002 and Roxio Cinematic.[1] In September 2011, Magisto introduced a cloud-based automatic video editing solution that uses proprietary intelligence technology to automatically analyze and understand user’s videos and edit them together with music and effects.[2]
