VTC-4000 INSTRUCTION MANUAL Page 17 of 27

RECORD END STILL ADVANCE

Changes the advance time, in frames, when the record end protect feature is activated. Change this setting
if you don’t like where the auto stop feature stops the tape before the end of a crash recording.

PROGRAMMED STILL MODE

Causes the programmed still feature always to be enabled. Programmed still is a feature that causes normal
or slow motion playback to slow to a still at the current event’s OUT point. This feature is normally enabled
by holding HOME and tapping UP arrow. Even when this menu item is enabled, a VTR must be selected for
programmed still to work

RECORD END STILL

Enables/disables the record end protection feature (default is disabled). This feature prevents playback from
“rolling-off” the end of a hard recording which would cause picture breakup. When a hard recording is
stopped, the end point is stored in a record end protect register. Any events that are marked during or
directly after recording, are assigned the record end protect register for that recording. After cueing into a
hard recorded location, as normal or slow speed playback nears the end of the recording, the speed is
ramped down to a still frame. Each time an event is recalled and used, it’s record protect register is also
recalled and used. Any time a cue or preroll is executed that has a record protect register assigned,
subsequent marking or setting of other events, provided the timecode is between the beginning and end of
the recorded segment, also are assigned the record protect register for that recorded segment.

NOTE: In order for record end protect to work, the master VTR must not be changed during playback. If the
master and slaves’ timecodes are different, the playback master must be the same as the master that was
used during recording.

CUEING ITEMS

A submenu containing these items:

SYNC LOOP MODE
SCROLL EVENTS
COPY RANGE
ERASE RANGE
CUEING EE MODE
F7/F8 TRIM TIME (switch option only)

SYNC LOOP MODE

Enables/disables automatic looping. By double-tapping the PLAY key while this feature is enabled, a
continuous loop will occur between the preroll point and the OUT point. If in gang mode, all devices will be
synched during the preroll duration. See VTR SELECTION, SYNCHED LOOPING. Default is disabled

SCROLL EVENTS

Scrolls through events using the Knob.

COPY RANGE

Moves ranges of events between areas within event memory. You may want to keep a range of events in a
reserved area of memory for later use.

ERASE RANGE

Clears any range of events to zeros.
