PREPARATIONS FOR OPERATION

Presetting and Recording of Time Code

The time codes from the internal time code generator can be recorded at the time of recording scenes.

The TC/UB/CLOCK menu screen differs depending on whether the FRAME RATE item on the VIDEO FORMAT

menu screen is “60/30” or “50/25”.

There are two ways to preset the time code.

Set from the TC/UB/CLOCK menu screen.

Set in the LCD screen without opening the menu screen. This section explains how to set from the TC/UB/CLOCK menu screen.

* See page 46 for instructions of setting from the LCD screen.

Menu and switch settings to set the time code preset are the same as the settings below.

Setting

To preset the Time Code, make the following settings.

„TC GENE. switch Set to REC or FREE.

REC

: The data preset in the time code generator

 

runs only during recording.

 

Use this setting if it is necessary to record

 

continual time codes across different scenes.

 

* However, approximately ±1-frame varia-

 

tions may occur in scene accuracy.

FREE

: The time code starts to run from the time it is

 

preset in the time code generator.

Use the DROP FRAME item to select the framing mode for the time code generator.

DROP

: The time code generator’s running method is

 

set the drop frame mode.

 

Use this setting when placing emphasis on

 

the recording time.

NON

: The time code generator’s running method is

DROP

set to the non drop frame mode.

 

Use this setting when placing emphasis on

 

the number of frames.

MEMO

Drop frame/Non-drop frame mode

In the NTSC system, the actual number of frames per 1 second is approximately 29.97 frames, but per time code 30 frames are processed. To compensate for this differ- ence, the mode called “drop mode” drops frame 00 and 01 for every minute not divisible by 10.

The “non-drop frame mode” is when no frames are dropped and the actual time shift neglected.

„TC/UB/CLOCK menu screen (FRAME RATE: 50/25) Whether or not user’s bit data should be recorded can be selected with the UB REC item on the TC/UB/CLOCK menu screen.

Presetting time code data

The time code and user’s bit data are preset on the TC/UB/ CLOCK menu screen.

1.Display the TC/UB/CLOCK menu screen.

Select the TC/UB/CLOCK item on the TOP MENU screen.

Time code (hour, min, sec, frame)

2.Set the time code (hours, minutes, seconds, frames).

1Rotate the SHUTTER dial to align the cursor (K) with TC PRESET, and then press the SHUTTER dial.

The first digit of the time code blinks. The blinking digit is the one to be set.

2When the SHUTTER dial is pressed, the blinking digit changes.

3When the SHUTTER dial is rotated, the value of the blinking digit changes.

When the SHUTTER dial is rotated upward, the value becomes higher. When rotated downward, the value becomes smaller.

4Repeat the procedure described in 2 and 3 above to set the desired value for all digits.

5After setting the frame digit, press the SHUTTER dial to make EXECUTE blink. The setting values are con- firmed when the SHUTTER dial is pressed again.

To cancel the setting, select CANCEL and press the SHUTTER dial.

3.When all the digits are set

Press the STATUS button to return to the normal screen

or

Rotate the SHUTTER dial to align the cursor (K) with the PAGE BACK item, and then press the SHUTTER dial to return to the TOP MENU screen.

Presetting user’s bit data

The user’s bit data are preset with the UB PRESET item on the TC/UB/CLOCK menu screen.

The method for setting is the same as the method for setting the time code described on the left.

The user’s bit can be specified using numerals or alpha- betic letters from 0 to F for each digit.

To record user’s bit data, set the UB REC item to ON (Only when set to FRAME RATE 50/25).

CAUTION

It is not possible to set all the digits of the user’s bit data to “F”.

Reading of the data during playback will not be possible for an all-F setting.

Zero-resetting the Time Code or User’s Bit Data

This is performed with the TC or UB PRESET item on the TC/UB/CLOCK menu screen. (Performed separately for the time code and the user’s bit data.)

1Rotate the SHUTTER dial to align the cursor (K) with the TC or UB PRESET item, and then press the SHUTTER dial.

2Rotate the SHUTTER dial to select ZERO PRESET as the setting value, and then press the SHUTTER dial.

MEMO

When a menu screen is not being displayed, you can zero reset the time code data by simultaneously holding down the USER2 button and the STOP button for about 1 sec- ond.
