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.
