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 into the middle of previously recorded scenes. CTL signals on tape in the recorder VTR are not overwritten. Video, digital audio, cue 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.

Time codes recorded during automatic editing During automatic editing, time codes recorded on the tape always follow immediately after time codes recorded right before an edit start point, regardless of the setting of the [F6] (TCG SOURCE) and [F7] (TCG MODE) buttons of TC menu.

For details on the switch settings necessary for changing the time codes recorded, refer to “4-3 TC Menu” on page 4-18 and the 600 menus in the VTR SETUP menu.

Editing precautionsUsing 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.

Video signals output to a monitor

While in E-E mode or when playing back in edit mode, the V-sync phase of the video output is delayed 6H (on the DVW-A500/1 and 500/1) or 4H (on the DVW- A500P/1 and 500P/1) with respect to the external reference signal. You can also adjust the V-sync phase so that it is in sync with the external reference signal phase, but without affecting the video signal delay. Change the V-sync phase through 701. SELECTION OF VIDEO/SYNC DELAY in the VTR SETUP menu.
