RS422
VTR LOCATE OFFSET
Most VTRs require a certain amount of ‘run up’ time when synced to
external equipment. This field sets that time. When a value is set
here, locating to any position will automatically cause the system to
locate to a point slightly earlier than actually specified. In the above
example, if you locate to 1 minute, the Akai machine will actually
locate to 55 seconds.
NOTE: YOU MUST SELECT ONE OF THE SMPTE/EBU+RS422 OPTIONS AT A FRAME
RATE APPLICABLE TO YOUR AREA WHEN USING RS422 MASTER.
These options are available at all frame rates. SMPTE/EBU from the VTR is still connected
as usual and the ON-LINE key must be switched on. The Akai machine will receive timecode
information in playback from the LTC connection but, when working in slow motion, it re-
ceives timecode over RS422 making locking of the two machines tighter.
LAYBACK FUNCTION IN RS422 MASTER
LAYBACK is a process where you have material on the Akai system that you wish to ‘master’
onto a VTR or other such RS422 equipped machine (such as an RS422 DAT machine). For
example, you may receive a video tape with just dialogue on it. This is sync-transferred to an
Akai machine where it may be edited and tidied up if necessary and sound effects, music and
other ‘sweeteners’ can be added using the Akai system’s multi-track capabilities. Finally, the
whole thing is transferred back to the VTR.
To use the LAYBACK function, press LAYBACK (F1/F2). You will see this screen:
The parameters are:
LAYBACK TO TRACKS Here you may select which of the VTR’s tracks the material will be
recorded to. You may select VTR tracks 1, 2, 3, 4, 5, 6, 7, 8 (mono) or
1+2, 3+4, 5+6, 7+8 (stereo) or 1-4, 5-8 or 1-8.
TRACKS ENABLED
Here you may select whether the layback (i.e. the mixdown) will be
to the VTR’s analogue tracks or its digital tracks. You may also select
DIGITAL which will cause the layback to be recorded to
both the analogue and the digital audio tracks of the VTR.
The soft key functions when LAYBACK key is pressed are:
PREROLL
Pressing this key will cause the VTR to locate to the IN time minus
the amount set in the VTR LOCATE OFFSET field (if this parameter
is set to zero, then the default value of 5 seconds is used).
PREVIEW
This allows you to ‘rehearse’ the layback (i.e. it will go into E-E mode
at the IN point and will then stop at the OUT point). This function
allows you to check whether the edit will be successful or not.
LAYBACK
Pressing this will initiate the layback process (i.e. the VTR will play to
the IN point and will drop into record on the VTR. When the OUT
point is reached, it will stop).
NOTE: If tracks are accidentally enabled for record on the Akai system, they will be ignored
when using the LAYBACK function.
