the VTRs; if this happens, the system should try again and will most likely succeed the second time. At the
edit IN point, both VTRs should go into edit recording color bars and reference tone. You can tap F2 during
the edit to see if VTR-2 is indeed in RECORD, then tap F1 to go back to VTR-1.
25. After the edit completes, the system should stop the VTRs and increment the event number to #001. The
out point from event #000 should have been copied into the IN point of event #001 for both VTRs. This
process is called AUTO TAGGING, which we enabled earlier. Auto tagging eliminates the need to set IN
points for successive sequential edits.
26. Tap OUT twice, 3000 (should see 00:00:30:00), ENTER.
27. Route Black & Silence into both record VTRs.
28. Hold REC and tap PLAY. Black will be recorded until 01:00:00:00 where we will begin editing.
EDITING
1. Route VTR-3 into both record VTRs.
2. Event #002 should be showing, with 01:00:00:00 as the IN point for both record VTRs.
3. Hold HOME and tap F3. This brings VTR-3, our playback VTR, into the gang.
4. Tap F4 then F3. F4 exits the gang, then F3 selects only VTR-3.
5. Find an interesting scene on the playback tape (using Shuttle) and use Jog to park on the first frame to edit.
6. Tap MARK. This marks the IN point to that frame.
7. Tap OUT. The OUT point shows.
8. Shuttle and/or Jog to the frame after the last frame you want recorded. Tap Mark to mark the edit OUT point.
9. Double-tap F1, then tap F1. This reenters the gang and selects VTR-1 as the master. Always select the
primary record VTR as the master before executing an edit.
10. Hold REC and tap PLAY. The first time you do this, VTR-3 may fail to synch because its ballistics haven’t
been learned yet. Synchronization and the edit should succeed the next try.
11. After the edit completes, all VTRs will stop, the event number will increment and the OUT point of the edit will
be set as the IN point of the next edit.
Repeat steps 4-11 for as many edits as desired. If you want to perform non-sequential edits, just mark the IN point
on either record VTR and copy it to the other by holding ENTER and tapping the other VTRs F-key. Note that
because we were performing assemble edits on VTR-2, before executing a non-sequential edit on that VTR, you
must change its record mode to INSERT and only edit where there is already video recorded. If you don’t want the
event incremented after an edit, disable AUTO TAG in the RECORD SETUP menu.
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
(isolated recordings made directly from key cameras to be used to replace segments on the master where mistakes
were made or where there is a better camera angle available than that which was chosen during the production).
Often live-to-tape productions result in a finished product (the master) that goes to air without any post production,
however, clean feeds and isos are made just in case some fixing in post is needed.
In this example, we will produce a master from a program feed from the production switcher (vision mixer), a clean
feed from the switcher before the downstream keyer, and two isolated camera recordings. We also will be rolling in
prerecorded material from a fifth VTR that will be shown on an on-set monitor and directly via the switcher.
PREPARATION
1. An important factor when recording a multiple camera television production, is the proper preparation of the
record tapes. Matching timecode is required and the tapes must have the same color frame relationship
between the timecode and the recorded video, or horizontal shifts are likely to occur during post production
editing *. The easiest way properly to prepare record tapes is to Black & Code blank tapes at the VTR using
the VTRs internal color framing capability. If you don’t want to take the time (or don’t have the time) to do
this, you alternately may record a small amount of black at the beginning of each tape before assemble
editing. The VTC-4000 color framing logic will maintain the color frame sequence from this initial recording
throughout the editing process. To check if tapes are compatible: Load two or more tapes into VTRs. On
the VTC-4000, tap HOME, SETUP, UP/DOWN until you see COLOR FRM MODE, ENTER and make sure
you see ENABLED (if not, tap DOWN, ENTER). Select a gang with these VTRs (Double-tap an F-key and
