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.
There are two types of video editing, linear and nonlinear, analog and/or digital.
Linear video editing is a video editing post-production process of selecting, arranging and modifying images and sound in a predetermined, ordered sequence. Regardless whether captured by a video camera, tapeless camcorder, 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.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".
It is the simplest method to publish. It is only necessary to push play and rec buttons. It is the method used for homemade videos, since it is the only possible edition.
This type of editing allows you to assemble the basic pieces of your various video segments. During an assemble edit, all signals (video, audio, and control track) are recorded. This type of editing is done in chronological order, piecing together edits back to back on the edit master tape. Assemble edits establish the time code/control track on your tape. When you perform assemble edits, the beginning of the edit is very precise and clean, but the end is very rough and uneven—the time code/control track breaks at the end of every assemble edit.
It is the most professional edit mode since it allows to select the elements to record (audio video or - CH1 or CH2 -). This way we will be able to record new signals on the tape without harming the rest of signals. In the magnetic stripe the image is placed in the top area and audio, divided in two channels, is placed in the bottom area. Therefore, the CH2 near to the edge of the magnetic stripe, can be damaged more easily. That is why this channel of audio will be used for ambient sound
Non-linear editing is a video editing method which enables direct access to any video frame in a digital video clip, without needing to play or scrub/shuttle through adjacent footage to reach it, as was necessary with historical video tape linear editing systems. It is the most natural approach when all assets are available as files on hard disks rather than recordings on reels or tapes, while linear editing is related to the need to sequentially view a film or read a tape to edit it. On the other hand, the NLE method is similar in concept to the "cut and paste" technique used in film editing. However, with the appropriation of non-linear editing systems, the destructive act of cutting of film negatives is eliminated. Non-linear, non-destructive editing methods began to appear with the introduction of digital video technology. It can also be viewed as the audio/video equivalent of word processing, which is why it is called desktop video editing in the consumer space.
