Insert recording offers the advantage of clean edits and the option of performing audio or video-only edits.
The editor can replace video, audio, or both without disturbing the tape's control track.
Videotape is blank when purchased, so before an this process can be made, the tape must have a control track recorded on it.
To do this, an assemble recording is made for the length of the videotape; this recording lays down a continuous, unbroken control track.
Such a process made on blank tape will not play back properly because the tape has no reference as to how to play the video.
Professional editing houses buy new videotape and have night-shift employees assemble record them to prepare them for use.
The assemble recording is usually a black picture with no audio, but it does have time code on it.
This black and coded tape is used as a record tape for insert recordings.
Therefore, when buying a record tape from a professional editing house, you will usually find that it already has the control track and time code on it.
To repeat, an assemble recording erases everything - all video, audio, and control track-and replaces it with totally new signals.
An insert recording replaces only those tracks (video, audio, or both video and audio) selected.
Insert recording is the method used by most professional editing companies.
The words insert and assemble are used in several ways in the video vocabulary.
An insert recording is done according to the method described above.
To insert an edit, however, means to place an edit between two other edits or to erase part of a previously recorded edit by inserting a new edit.
The insert edit is made using an insert recording.
