Section 10 – Operations related to timecode
10-2 – 1.00 – 06/97
To change between the two different time refer-
ence modes, perform the following procedure:
1) Select menu group 3 and press
ENTER
:
2) Select
and press
ENTER
.
3) You can use the
UP
and
DOWN
keys to select
either
(absolute) or (timecode).
The appropriate indicator by the tape counter
(either
ABS
or
TC
) will light.
10.1.4 Location point settings
10.2 Tape timecode mode
The following procedure allows you to select the
source for tape timecode (including ABS timings
used to synthesize SMPTE timecode. This synthe-
sized timecode is treated exactly as if a tape had
been striped with timecode).
1) Go to menu group 5, move the cursor to
, and press
ENTER
:
2) Use the
UP
and
DOWN
keys to choose between
the various options:
, ,
, and .
These options are all described individually below.
10.2.1 TcTrack setting
This is the one setting in this menu which does not
use the ABS conversion facility. You should only
use this setting if you have already striped the ded-
icated timecode track with timecode (either from
an external source or from the DA-98’s own inter-
nal generator).
If you have selected
in the menu
above, any timecode recorded on the tape will be
used as the tape timecode source.
10.2.2 ABS setting
If you have selected in the menu above, the
ABS subcode time from the tape will be used as
the timecode, with the start of the tape having a
timecode value of 00:00:00:00, as with the ABS
code itself.
The timecode frame rate used will be the frame
rate as selected in 10.3, “Selecting the frame
rate”).
10.2.3 ABS-Ofs setting
As with the previous setting, this converts the
ABS subcode timing to timecode, but allows you
to add an offset to the absolute value so that the
timecode does not start at the zero point.
When you select this option, the display will
change to allow you to enter an offset time:
NOTE
If you change an offset value (timecode or ABS), any
punch points, location memories, etc. will be invali-
dated. For example, if you change the offset to
00:30:00:00 (30 minutes) from 00:00:00:00 (no offset),
a punch point which was previously at 00:33:00:00 (33
minutes into the tape) will still have the same value
(00:33:00:00), but will now be only 3 minutes into the
tape.
NOTE
If you are using ABS timings as timecode, the hours,
minutes and seconds of the ABS time will correspond to
the converted timecode,
unless
the frame rate is set to
29.97 non-drop or 30 drop. In these cases, the difference
between ABS values and timecode values will be about
2 seconds per hour.
