9 – Operations related to timecode–Tape timecode mode
9.2
Tape timecode mode
The following procedure allows you to select the
source for tape timecode when
selected, as described above (including ABS timings
used to synthesize SMPTE timecode. This synthe-
sized timecode is treated exactly as if a tape had been
striped with timecode).

and
These options are all described individually
below.
9.2.1
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 are using the dedicated timecode
track with recorded timecode (either from an external
source, from the DA-98HR's own internal generator
or synthesized or assembled from ABS).
TcTrack
If you have selected
above, any timecode recorded on the tape is used as
the tape timecode source.
If no timecode has been recorded on the tape, the
tape counter shows all dashes
See 9.5, "Timecode input and output" and 9.3,
"Recording timecode" for details of how to use this
timecode setting.
9.2.2
ABS setting
This setting, and the settings following, synthesize
timecode from the ABS subcode.
ABS
If you have selected
ABS subcode time from the tape is used as the time-
code, with the start of the tape having a timecode
value of 00:00:00:00, as with the ABS code itself.
A negative ABS value in this mode is converted to a
"before midnight" time.
The timecode frame rate used is the frame rate as
selected in 9.4, "Selecting the frame rate".

NOTE
If you are using ABS timings as timecode, the hours, min-
utes 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 two cases, the difference
between ABS values and timecode values will be about 2
seconds per hour.
9.2.3
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 changes to
allow you to enter an offset time:

1 Use the Ó and Á keys to choose the field to
change (hours, minutes, seconds or frames)
and then use the § and ¶ keys to change the
value of that field.
You can also enter a time offset directly using
the function keys (4.4, "Using the function keys
as number keys").
The time you enter is the time at which the timecode
starts from the beginning of the tape. For instance, if
00:59:00:00
you enter an offset of
is positioned exactly 1 minute after the start, the
01:00:00:00
timecode is
9.2.4
ABS-13 and ABS-23 settings
These settings are useful if you are recording many
pieces on one tape. They automate the process of
providing a timecode "pre-roll" and starting each
piece at an easily-memorable timecode position.
The ABS-13 setting should be used to record pieces
of 10 minutes or less in length, and the ABS-23 for
pieces of 20 minutes or less.
With both of these settings, the start of the tape is
automatically set with an offset of
hh
where
is the number of hours.
