Chapter 4 Adjustments and settings for recording (continued)

Example 2: When connecting a multiple number of units and using one of them as the reference unit

TC OUT

MON OUT (HD-Y)

In the unit, there is a video signal delay in the camera, which is required or the process of converting video images taken with the image-shooting element from the progressive signals to the interlace signals. Since time is required for making the 2:3 pull-down from the 24P frame, there is a video signal delay in the camera. When recording from a device that can record images without a delay and the unit is connected in parallel, it is necessary to synchronize the time code. To set this timing, open the <TC UB> screen from the VTR MENU page and set it in the TC VIDEO SYNCRO item.

<Note>

The system can be configured with multiple units by opening the <GENLOCK> screen from the SYSTEM SETTING page and setting the GL PHASE item to the connector using menu operations.

The phase of the time code can correspond to either the HD- Y output signals of the MON OUT connector or VBS output signals of the VIDEO OUT connector. However, the same value should commonly be set to the GL PHASE for all cameras. If different values coexist in the system, the shooting timing may not correspond to each other.
