SHOOTING OPERATION

HEADER REC Function

When the REC/VTR trigger button is pressed while the STOP button is pressed, this function first records the color bar video and the test tone (1 kHz sine-wave) of the built-in signal generator at the beginning of the tape. Then it records the black video signal and the mute audio signal for the duration specified in advance. When the recording is completed, this device enters the Record- Standby mode. The time code value at the Record-Standby position becomes the time code specified in advance. (HEADER REC function)

•Settings related to the HEADER REC function, such as whether the HEADER REC function should be enabled, the HEADER REC execution duration, and the time code value setting when the HEADER REC recording is completed, etc., are made on the HEADER REC menu screen.

•The HEADER REC function is enabled when TCG SOURCE on the TC/UB/CLOCK menu screen is set to INTERNAL.

•The HEADER REC function is executed under the following circumstances: CAM/VTR button: Set to CAM mode.
