Externally Locking the Time Code

The unit’s internal time code generator can be locked to an external generator. In addition, the external time code generator can be locked to the unit’s internal generator.

Example of connections for external locking

As the figure shows, connect both the reference video signal and reference time code.

For more information about the reference video signal and GENLOCK, see [Setting External Reference Signal and GENLOCK] (page 61).

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

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, set it in the TC VIDEO SYNCHRO item. The menu item TC VIDEO SYNCHRO is found in the <TC UB> screen on the MAIN OPERATION page.

Set by referring to the connection example.

‹Note

This setting is enabled during progressive shooting (when CAMERA MODE is 24P, 30P, 25P), and when the Scan Reverse function is operating. This setting is unnecessary during normal recording (when CAMERA MODE is 60i, 50i).

‹Note

If you make a system with more than one unit, use the same settings for all cameras for input and output. When different settings are mixed, the image timing will not match.
