Features of the VTR unit
Digital system
The pictures are compressed by a component digital
recording system that uses the latest compression
technology while non-compression PCM recording
featuring excellent signal-to-noise ratio, frequency
band, waveform characteristics and reproduction of
detailed areas is employed for the sound. The result
is an even higher picture and sound quality.
Power saving management (SAVE REC) function
When this unit is used for recording, its playback
system circuitry is shut down. The output of signals to
the HD SDI OUT connector is also shut down when
the cable has not been connected so that the unit’s
power can be conserved while the unit is being
operated.
Scene-to-scene continuity
Simply by pressing the VTR START button or lens
VTR button, continuity between the scenes is
obtained at a precision of 0 to +1 frame.
Rec review function
The last 2 to 10 seconds of a recording are
automatically rewound and played back to enable the
user to quickly check what has been recorded.
Playback function
This function enables the playback picture (in black
and white) to be viewed on the viewfinder screen.
Color playback pictures can be output from the HD
SDI OUT connector.
Built-in time code generator/reader
The same or separate time code information can be
recorded on the dedicated sub-code track and video
AUX area, and played back.
External locking of time code
The built-in time code generator can be locked to an
external generator. A lithium battery is used as the
backup power supply of the built-in time code
generator to back up the memory data for about a
year even when no power is supplied to the unit.
Tape management information
This camera/VTR automatically stores as the tape
management information both the frame rate
information which indicates the shooting speed and
the active frame information which indicates the first
frame where the frame image was switched in the
user’s bit of the sub-code track area (this used to be
the LTC area).
Built-in DOLBY NR system
The cue audio recording circuitry contains a Dolby B
noise reduction circuit.
Audio functions
OA phantom power supply type of microphone
(optional accessory) with sharp directivity
characteristics can be attached. It can also be
detached from the unit for use as an interview
microphone.
OOther kinds of microphones can also be connected
and, using the model AJ-MH700P microphone
holder (optional accessory), attached to the unit.
NEWS REC function
This function especially supports shooting in the
context of news gathering or documentary filming to
ensure that no opportune shutter opportunities are
passed up.
In other words, by controlling the start key
acknowledgment time, the unit can continuously
record without the user having to interrupt the
recording: this safeguards against the failure to record
those precious moments—a failure that occurs when
recording is resumed after it has been shut down
temporarily.
RETAKE function
This function is for not leaving behind superfluous cuts
when a cut turns out to be no good during the
shooting of news, reports or art programs.
Users should remember to handle this function very
carefully.
If there is enough leeway in the shooting time and a
particular cut is clearly judged to be no good, the tape
is rewound to the start of the cut concerned and the
rec pause (rec standby) mode is established by
operating the MODE CHECK button and lens RET
button. Since recording is now commenced from that
point on the tape, the no-good cut will be deleted. In
order to prevent the cut prior to the no-good cut from
being deleted, a part of the no-good cut equivalent to
ten or so frames is left behind.
By cutting down on the time taken for copying onto the
work tape, for instance, this function is very effective
in achieving economical operation.
INTERVAL REC function
This function makes simple interval shooting possible.
It proves to be very effective when shooting programs
with a nature theme or art programs.
