Page 4: Introduction
VIDEO SERVER CONTROL USING VDCP PROTOCOL This version of the VTC-4000 system is optimized for control of videotape based recorders, however it is capable of controlling video servers in timecode only mode (clips must be loaded at the server, then transport functions can be controlled like a VTR). -
Page 5: Physical
25FPS or 24FPS are used. In addition to showing master VTR timecode, the top line of the VTC-4000 STATUS display shows a reference indicator in the 4th character position whenever reference is applied to the RM-4000. The reference indicator character is... -
Page 6: Operation
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. -
Page 7: Vtr Selection
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 7 of 27 VTR SELECTION The F1-F10 VTR Selection keys directly select any of the ten VTRs connected to the RM-4000 as the “current” VTR; the selected VTR is indicated by a solidly lit green (left hand) LED above the key. Commands are sent only to that VTR. -
Page 8: Synched Looping
VTRs continue to roll on their own, so another timeline operation may then be used. PERSONALITY REGISTERS The VTC-4000 is equipped with ten personality registers. There are many user adjustable settings in the system, most of which can be stored in personality registers. Saved personality configuration data are protected by an error detection value. -

F8, or subtracted with F7. COLD BOOT If for any reason, you wish to reset the VTC-4000 back to the factory preset configuration, a “COLD BOOT” may be performed. This operation erases all events, and some internal registers; personality registers are not affected. A cold boot is accomplished by unplugging the modular cable from the rear of the panel, and holding the MARK and PLAY keys down while plugging the cable back in. -
Page 10: Menu
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 10 of 27 MENU Many operational settings are adjustable by using the menu system. A separate MENU display is used so that VTR transport controls and status/timecode display are always active, even while navigating the menu. There are two exceptions to this: Some menu items use the KNOB, so it will not control speed while in such a menu item. -
Page 11: Set The Edit Duration
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 11 of 27 SET THE EDIT DURATION Tap the OUT (DOWN arrow) key while in the SET OUT mode to change the MENU display to the SET DUR mode. This allows you to define the edit length by DURATION rather than by an explicit OUT point. -
Page 12: Record Setup
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 12 of 27 RECORD SETUP Tap the HOME key followed by the SETUP key to enter the RECORD SETUP menu. The record mode in effect for the current VTR is shown on the upper MENU display line. Tapping VTR selection keys (F1-F10) show the current record modes for each VTR. -
Page 13: Gpi Edit Enable
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 13 of 27 A feature is available that prevents playback from rolling past the end of a hard recording, see RECORD END STILL. OPEN ENDED ASSEMBLE EDIT Same as ASSEMBLE EDIT (see below) except the DURATION is ignored, and recording continues until the STOP key is tapped. -
Page 14: Gpo Settings
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 14 of 27 GPO SETTINGS GPI EDIT ENABLE Enables/disables the GPI backspace edit feature per VTR (default is disabled). If enabled and the VTR is set for HARD RECORD, when the VTR's GPI input goes active (low) a record command is sent to the VTR, when the GPI goes inactive a Stop command is sent. -
Page 15: Menu Items
* The numeric keypad style is never erased even by a COLD BOOT or the INITIALIZE UNIT menu. Many aspects of the way the VTC-4000 works are adjustable by the user. Almost all of these settings are stored in registers called Personality Registers. Ten personality registers are provided, allowing different users to store their favorite configurations. -
Page 16: Forward Speed Limit
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 16 of 27 SAVE PERSONALITY Saves the current configuration in a personality register. Tap numeric keypad keys after selecting this item to show the names of the various registers. Tap ENTER when an unused register is seen (indicated by the name DEF for default). -
Page 17: Cueing Items
Version: 100505 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. -
Page 18: Time Code Items
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 18 of 27 CUEING EE MODE Causes the VTR to output its input video while cueing. This is useful for dubbing operations: black video input to the source VTR is output to black the record VTR’s tails after a dubbing pass while the source VTR is cueing for the next pass. -

Page 20: Miscellaneous Menu Items
Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 20 of 27 STOP KEY FUNCTION Changes the function of the STOP key from the Stop command to Jog still. The default is still. SHUTTLE FORWARD AND REVERSE LIMITS Specifies the maximum Shuttle speeds, expressed in multiples of Play speed. This feature allows Shuttle speed to be limited to that witch provides the best compromise between speed and recognizable picture. -
Page 21: Options
OPTIONS RS-232 OPTION The -RS option is an RS-232 interface that is used to control the VTC-4000 system remotely. VTR timecode and status, Menu display, and selected VTR information are accessible. Keystrokes can be simulated, and personality data can be downloaded and uploaded. The 9-pin-D connector on the BNA-1001-RS BUFNET/RS-232 adapter connects pin for pin to a 9-pin ‘D’... - Page 22 Version: 100505 VTC-4000 INSTRUCTION MANUAL Page 22 of 27 Simulate hold Home & F-key to add/remove gang slaves where n = a-j for slaves 1-10. G<CR> Mm Ss[s…]<CR><LF> Request Currently Selected VTR(s) where m is the master and s are one or more slaves. If any s entries, even if only same as m, system is in gang mode.

Page 23: The Switch Option
RS-422 ports can be connected to additional external controllers. Control of each device is switched between the VTC-4000 and the external controllers by holding F10 or F9 while tapping the F1-F6 keys. When control of a device is released to an external controller, the red (right) LED above the device’s F-key flashes at a medium rate. -
Page 24: Operation Examples
Page 24 of 27 OPERATION EXAMPLES These examples assume that the VTC-4000 panel and RM-4000 Remote Processor have been installed as described in the INSTALLATION section of this manual. All RS-422 ports operate identically and the actual ports used in these examples are unimportant and have been identified only for illustration purposes. These examples assume a routing switcher is used to connect signals from a test signal generator (for Black and Bars) and VTRs to VTRs. -
Page 25: Editing
EXAMPLE #2 - LIVE TO TAPE RECORDING This is a step-by-step example of using the VTC-4000 system to record a typical live-to-tape production. The end result of a television production should be a master (and an optional backup master), a clean feed (same as the master, but without titles in case spelling or other errors need to be fixed later), and one or more iso’s... - Page 26 3. When using the VTC-4000 system to record multiple camera shoots, it is not necessary to route timecode to the record VTRs and operate them in external regen mode. The VTC-4000 performs frame accurate edits, and if the IN points are the same, timecode will match.

F-key to select that VTR as the gang’s master. Make a test edit to check that everything is OK and to allow the VTC-4000 to learn the roll-up ballistics of the VTRs. Hold REC and tap PLAY. The record VTRs should all cue to the preroll point, and then synch for edit.
