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 1: When locking onto an external signal Reference time code TC IN GENLOCK IN SDI IN Reference video signal 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 screen on the MAIN OPERATION page. Set by referring to the connection example. Setting of the TC VIDEO SYNCHRO item Item TC VIDEO SYNCHRO Variable range Remarks 0 For setting to correct the time code 1 according to the delay of video signals. 2 0: Do not correct. 3 1: To delay the time code to be input according to the timing of the video images. 2: To forward the time code to be output according to the timing of the video images. 3: To delay the time code to be input and forward the time code to be output, respectively, according to the timing of the video images. ‹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).

When different settings are mixed, the image timing will not match. 68 Adjustments and Settings for Recording : Setting Time Data
