OPERATION
BASIC OPERATION
VTRs are selected by tapping corresponding VTR selection keys (F1-F10), or by double-tapping them for ganged
operations (see VTR SELECTION below). Separate keys control the basic VTR transport functions: Play, Stop,
Rewind, and Fast Forward. The SHTL key puts the VTR in high speed Shuttle mode at still speed; the Knob is
then used to vary the Shuttle speed. Still Shuttle is resumed anytime the SHTL key is tapped. The JOG key puts
the VTR in the Jog mode; tape moves at a speed relative to Knob rotation, and stops when the Knob is released.
The SLOW key puts the VTR in the Variable Play mode at still speed, 100% (Play) speed if entered from Play
mode or at the speed stored with the last used event. Turning the Knob changes the speed. The ENTER key
stores the slow speed along with the current event so that as events are recalled and used, the slow speeds stored
with them are recalled also.
EJECTING TAPES AND SCANNER CONTROL
When in the Stop or Jog modes, the STAND BY key spins the tape scanner down to prevent tape and head wear.
When the scanner is already down (STOP, READY OFF on the Status display), STAND BY spins the scanner up,
preparing for immediate playback. A double-tap of the STAND BY key ejects the tape cassette (if in Stop, Jog, or
Ready Off modes).
RECORD
First you must select a record or edit mode using the RECORD SETUP menu. Recording is then performed by
holding REC and tapping PLAY. If in the gang mode (see VTR SELECTION below), all ganged VTRs will roll for a
record operation. VTRs set to RECORD INHIBIT will roll for playback. All ganged VTRs will roll in synch for frame
accurate editing, except those set to HARD RECORD mode. VTRs set to HARD RECORD will go into record as
soon as REC/PLAY is hit while VTRs set to edit or playback modes are cued to the preroll point. To abort a
ganged edit in any mode (even if the involved VTRs are not selected), hold the REC key and tap the STOP key.
Auto-tagging will not occur if recording is aborted in this manner. Any VTR involved in a ganged edit can be taken
out of the edit by selecting that VTR and pressing STOP (make sure gang mode is not in effect); this VTR can now
be controlled independently while the edit continues with the remaining VTRs.
A record end protect feature is available that prevents playback from rolling past the end of a hard recording, see
RECORD END STILL.
Input video and audio can be selected to pass through the VTR (EE mode) by a single tap of the REC key. Any
other transport control key returns the VTR to Tape mode. The EE switch will not occur while in gang mode.
A GPI backspace edit mode can be enabled that allows hard recordings or open ended insert or assemble edits to
be controlled for each VTR via GPI contact closure.
PREVIEW (REHEARSE)
To rehearse an edit operation, double tap the REC key. The VTRs will roll as for record, except the selected
channels of the record VTR(s) will go into EE mode during the record period instead of entering edit mode. The
existing program material will remain unaltered.
LOCATING OPERATIONS (CUEING)
The VTC-4000 is equipped with a powerful autolocation capability. Five hundred tape locations per VTR may be
marked to VTR timecode or may be set explicitly using the numeric keypad. VTRs may be cued to any location,
with or without preroll. See EVENT MANAGEMENT for more information about locating.
SLOW MOTION
Tap the SLOW key to enter the Variable Play mode. If Slo-mo preset mode is enabled (see VP PRESET MODE),
the slow motion preset mode is entered instead. In VP PRESET MODE, a variable speed may be preset and is
shown on the display, tap SLOW for the preset speed to take effect.
