6-1-1 Overview of Automatic
Editing
Automatic edit modes
The VTR provides the following two modes for automatic
editing:
Assemble mode
New scenes are added to the end of previously recorded
scenes.
CTL signals, time codes, video and audio signals on tape
in the player are recorded onto tape in the recorder VTR.
Insert mode
New scenes are inserted between previously recorded
scenes.
CTL signals on tape in the recorder VTR are not
overwritten. Video, digital audio, and time code signals
can be recorded separately.
Both of these two edit modes support DMC editing. In
insert mode, you can also use split editing.
Interpolation of time codes by the CTL counter
To use time codes as addresses of edit points, the time
codes must be recorded on the tape in ascending order.
As long as they are in ascending order, time codes do not
have to be continuous. The CTL counter automatically
interpolates data for editing even if there are breaks in the
continuity in the time codes.
Steps in automatic editing
The sequence of steps that are taken to do automatic
editing with two VTRs is as follows:

Editing precautions
Using an editing control unit
When using an editing control unit to control the VTR, set
the edit delay on the control unit so that CUT-IN and CUT-
OUT commands are sent to the VTR five frames ahead of
the actual edit point.
