11 EDITING
11-1 OUTLINE
Two electronic editing modes are available: insert editing and assemble editing. Signals from a video camera, on-
air signals and playback signals from another VCR can be used in either type of editing.

With assemble editing, scenes are added one after
the other in predetermined order. Video, audio, and
control signals are recorded simultaneously. To
ensure stable editing, CTL signals must be recorded
prior to the first edit point for a period exceeding the
preroll time (typically, about 30 seconds).

Insert editing allows you to insert new audio or video material between existing scenes that have already been recorded. You can choose different video and audio and combine them for insertion. CTL signals must be recorded continuously in the section where the new material is being inserted. Before editing, record CTL signals for a period exceeding the editing time.

*Since the full erase head operates during assemble editing, a non-recorded segment is produced after the postroll point. If assemble editing is applied in the middle of a recorded tape, the picture will be distorted after the postroll point.

• No. 009 <CAP RE-

Recording

●Color frame information is always recorded regardless of the setting of the front sub panel’s CF switches and menu switches (except during editing).

NTSC : 4-field color frame

PAL : 8-field color frame

●During recording, the CF indicator lights on the counter display.

●If you want to synchronize time code with color frame, set menu switch No. 421 <TCG CF FLAG> to “ON” or “AUTO”.

●To record CTL signals, record a black picture from the built-in signal generator or connect a camera or a standard TV signal generator and record the output signals.

●Editing is not possible from the very beginning of the tape. The first edit-in point must be registered after the preroll section.

●Audio signals are not output when color bar signal from the built-in signal generator are inserted for editing (including preview). Do not select the audio channel for insertion of the color bar signal from the built-in signal generator. It may not be possible to insert the signal properly on the audio channel.

LOCKING DIR.>

Selects the direction of

the color frame servo

lock.

• No. 387 <CF FLAG

REPLY>

Selects the field unit for

the color frame flag

transmitted from the 9-pin

remote control connector.

Playback

The color frame servo function can be set with the front sub panel’s CF switches and menu switches.

	Front sub panel switch setting
	• Set menu switch No. 008 <CAP LOCK (525)> or No. 008p <CAP LOCK (625)>
	to “SW SEL”.
	• Set the [CF] switch on the front sub panel to “ON”.

●Preroll time

It takes a few seconds for the tape to stabilize after tape running is started. To ensure that the tape is stable before it reaches the edit point, the tape must start running a few seconds before the edit-in point (prerolling).

Select the preroll time from 0 to 15 seconds with the recorder’s menu switch No. 320 <PREROLL TIME>. Use the remote control setting only when executing editing via a remote controller.

●CTL counter values based on the TIMER-1 PRESET command (44.00) from the editing controller can be preset only in the Non-drop Frame mode (NTSC).

●Program Playback speed can be varied between 90% and 110%. The range is always the same even if an external controller or other unit is connected that sets the range outside this limit.

Cautions

●The displayed image may be distorted when the editing mode is preset from an editing controller during editing or the mode is switched between EE and PB. This is normal. It is not a malfunction. The distortions appear in the editing output image but are not recorded.

●The V. Fade function may not function correctly when a tape with edited audio is played back. This is normal. It is not a malfunction.

●Noise may be recorded if all insert modes are canceled during editing with any of editing mode select buttons. This is normal. It is not a malfunction.

●Noise may be heard when editing is on or off in the Playback mode. This is normal. It is not a malfunction.

(See page 106.)

• No. 421 <TCG CF FLAG>

Turns the color frame flag

for the time code bit ON/

OFF. (See page 106)

 Color frame editing is still

possible even when

material that does not

contain color frame

information (have no 4-field

NTSC color frame

information or 8-field PAL

color frame information) is

inserted in a color frame-

recorded section. Once the

new material has been

inserted, color frame

editing can be performed

by re-editing. In this case,

the [CF] indicator on the

main unit lights.

	For PAL, select the 4 or 8-field color frame servo with the [4/8] switch.
	When the [CF] switch is set to “OFF”, the frame servo is activated.
	Menu switch setting
	• For NTSC, set menu switch No. 008 <CAP LOCK (525)> to “4FIELD”.
	• For PAL, set menu switch No. 008p <CAP LOCK (625)> to “4FIELD” or
	“8FIELD”.

Menu switch No. 008 <CAP LOCK>
SW SEL : Select with the front sub panel’s [CF] switches.
2FIELD	: Playback is performed with the 2-field servo system. Color framing is
	not executed.
4FIELD	: Playback is performed with the 4-field color frame servo system.
8FIELD	: Playback is performed with the 8-field color frame servo system (PAL
	only).

●[CF] indicator

If the front sub panel [CF] switches are set to any position except OFF, the CF indicator lights whenever a tape with color frame information is played back.

Editing precision during color frame editing

When the color frame servo function is used, the edit point may shift to maintain color frame continuity even though menu switch No. 393 <SYNC GRADE> is set to “ACCURATE”.
