4 RECORDING & PLAYBACK

4.1 Recording

4.1.1 STANDARD RECORDING PROCEDURE

Pressing the REC button on the front panel will automatically put the V1 into "RECORD READY"

mode or "INPUT MONITOR" mode, the red LED will go ON. This is useful for monitoring the input

audio and video before you record. To turn "INPUT MONITOR" OFF press STOP. A drive must be

formatted then initialized before it is ready for recording (See Section 2.1, Menu (08), "FORMAT " ).

To begin recording from "STOP" or "RECORD READY" modes, hold down REC and press PLAY,

both green and red LEDs will go ON simultaneously.

To begin recording from "PLAY" mode with the Edit Preset Video "ON", hold down PLAY and press

REC, both green and red LED will go ON simultaneously.(See Section 2.2, Optional Menu (02), "Edit

Preset"). To stop recording but keep playing, press "PLAY" or press "STOP" to stop everything.

4.1.2 OVERDUBBING VIDEO & AUDIO TRACKS

To overdub both video and audio on a section of your disk, you need to execute the Chase Command by

holding the OPTION key while pressing PLAY (See Section 4.2.1, "CHASE command").

♦ Use Optional Menu (02) Edit Preset and select Insert ON then select A1 ON, A2 ON and Video

ON.

♦ Both, the source machine and the V1, should be synchronized

to the same reference (House Sync)

and time code should be fed from the source machine into the TIME CODE IN of the V1.

♦ Execute the Chase command by holding down the OPTION key and pressing PLAY

♦ Place the V1 into "INPUT MONITOR" by pressing the REC button

♦ Begin playback of the source machine before the section that you want to overdub. The V1 will begin

playing as soon as it sees time code that matches what is on the current disk. Wait until the V1 LCD

shows PLAY with a black dot, this indicates that the V1 is playing in sync and chasing the time code

from the source machine.

♦ When you reach the point where you want to punch in, hold down PLAY and press REC to start

recording. Press PLAY or STOP to stop overdubbing.

4.1.3 OVERDUBBING/INSERT OF AUDIO TRACK(S)

This feature allows the insert/overdub of selected audio track(s) on existing recordings while the other

track(s) will be monitored at the same time. The insert/overdub feature is only supported on the Seagate

Ultra SCSI hard drives at a compression ratio of 8:1 2 fields or higher ratios, this feature can also be

used with other drives but in higher compression ratios. Users who want to use this feature with other

drives should test how low in compression they can go before committing to a compression ratio. PAL

users have reported that they can use this feature at 12:1 2 fields on a Jaz 1GB drive (The transfer to disk

in PAL mode is faster then NTSC). To use this feature:

♦ Use Optional Menu (02)

Edit Preset to select which audio track(s) you want to insert.

Provide the same House Sync to the source machine and the V1.

♦ Connect the time code out from the source machine into the TIME CODE IN of the V1.

♦ Begin playback of the source machine before the section that you want to insert on the V1.

♦ Hold down

OPTION and press PLAY (Chase Command) to engage synchronized playback with

the source, wait until the V1 LCD shows "PLAY" with a black dot (This indicates that the V1 is now

in sync with the source), then hold down

PLAY and press REC. The V1 will record the insert. Then

press STOP or PLAY to end the insert segment procedure.
