Preread Editing
Video and audio signals already recorded on the recorder tape can be used
as an edit source for insert editing. This type of editing is called “preread
editing”, as the VCR uses the preread heads to read the signals in advance
from the tape.
The video signals read out by the preread heads can be sent to a video
switcher, and combined with video signals from the player for recording.
The audio signals read out by the preread heads can be sent to an audio
mixer for mixing with audio signals from the player for recording, and can
be recorded either on the original channels or on other audio channels.
